More antipsychotic medications are available
than ever before. The good news about this is that there are
more treatment options to choose from, and more people may
find a medication that works better for them. But having more
choices also means more decisions to make. This web page
presents the pros and cons of changing medications to help you
make a well-informed decision together with your doctor about
which antipsychotic is best for you.
The Basics of Antipsychotic Therapy
Before talking about changing medications, it is
important to be aware of basic information concerning
antipsychotic medication. These basics are true for ALL the
antipsychotic medications—old and new.
It is well established that antipsychotic
medications are necessary for a person who has a diagnosis of
schizophrenia or a similar kind of psychotic condition. So, if
you have been diagnosed with schizophrenia or a similar
psychotic disorder, the question is not whether you need to
take an antipsychotic medication. The question is whether you
are taking the medication that’s best for you or whether you
should consider changing your medication.
How Do Antipsychotic Medications
Help?
- Antipsychotic medications treat psychosis—this means
they control psychotic symptoms such as hallucinations and
delusions.
- Antipsychotic medications are very helpful in keeping
psychotic symptoms from coming back.
- Antipsychotic medications help people stick with other
kinds of therapy.
- Antipsychotic medications make it easier to handle the
stresses of daily living, such as going to school or going
to work.

What Kinds of Problems Can Antipsychotics
Cause?
You probably already know that antipsychotic
medications are far from perfect. Listed below are some of
their drawbacks.
- Antipsychotics do not cure schizophrenia. Rather,
they tend to control the symptoms or keep them from
coming back (relapse prevention).
- Most of the time, medications are not 100% effective in
controlling all the symptoms a person has. Most people still
have to put up with some symptoms of their illness.
- All antipsychotic medications have side effects. Some of
these side effects can make people uncomfortable. Sometimes
antipsychotic medications can make people look “medicated,”
which can be embarrassing. Other side effects can even be
dangerous. Fortunately, newer medications called atypical
antipsychotics have fewer side effects and work to control
the symptoms of schizophrenia at least as well as the older
conventional medications.
If you’d like to know more about the symptoms of
schizophrenia or how antipsychotic medications work, please
refer to the TRUST brochures Understanding
Schizophrenia and Managing Schizophrenia for more
information. The goal is to get the most good (benefit) from
your medication with the fewest possible side effects.
Is Your Medication Doing a Good Job? Give It
a Report Card!
The first step in deciding about switching
medications is to ask yourself how well the medication you are
taking now is working for you. It may help to give your
medication some grades, just like on the report card shown
here.
|
Sample Report Card for Current
Antipsychotic Medication |

don’t need to be in the hospital I can do many of the
things I want to do
|
A- |

Controls my symptoms (e.g.,
hallucinations, delusions) Examples: Keeps down
the voices in my head I want to be around friends and
family |
B |

Side effects don’t bother
me Examples: I don’t feel stiff I don’t
feel “slowed down” or tired My hands don’t shake I
don’t feel restless I have not gained weight I
don’t have sexual difficulties I can go about my
daily life
|
B+ B+ B B+ A- B- A-
|
Use the “report card” below to grade your
medication. Give your medication an “F” if it doesn’t help at
all or causes terrible side effects. Give it an “A” if it
really helps and has very few bothersome side effects. Grades
of D, C, and B fall in between. If you don’t know for sure,
just put a question mark (“?”) instead of a grade. Feel free
to add to the report card any symptoms and side effects that
are especially important to you.

If you are not happy with the grades you gave
your medication, check with your doctor or treatment team to
try to figure out whether the problem is from the medication
or from something else. Also check whether there are some easy
things the doctor can do to improve your medication report
card.
This report card is just a starting point. If
you give your current medication bad grades, this doesn’t mean
that you should stop or change your medication. It means that
you should TALK WITH YOUR DOCTOR about what’s wrong and
possible ways that you might be able to do better. For
example, if the report card shows that your medication is
falling short, it may be that the dose is not right, that you
may not be taking it properly, or that something else (like
alcohol or illegal street drugs) is keeping your medication
from working. The next section gives some reasons why your
medication might not be working as well as it could.
Top
Getting the Most From Your Medication
OK, you’ve done a report card on your
medication. If it got straight A’s, congratulations! It means
that your medication is working. But, just as most people
don’t get straight A’s in school, it’s more likely that your
medication didn’t get straight A’s. If it didn’t get good
grades in every area, you and your doctor need to figure out
why. You can then decide what, if anything, can be done to
improve the situation and whether it’s worth trying to make it
better.
For antipsychotic medications to do their job
properly, they have to be given and taken in the right way.
Other things that can affect the way antipsychotic medications
work are listed below:
- Diagnosis. It is important to match the
medication with the diagnosis. Since you are reading this
web page about antipsychotic medications, it is assumed that
this kind of medication is appropriate for your illness. If
you have any questions about your diagnosis, ask your doctor
or treatment team.
- Drinking and Drugs. Avoid drinking alcohol and
using illegal street drugs. They can prevent your
antipsychotic medication from doing a good job. Even just
“once in a while” drinking or drug use can make your
symptoms worse. If you are drinking or using drugs, it is
very hard for your doctor to know what problems are being
caused by the drugs or alcohol and what problems are being
caused by your illness or by the medication not working
well.
- Medicine (antipsychotic medication) choice. There
are many different antipsy-chotic medications, and they are
not all the same. You will hear more about the different
medications later in this web page.
- Dose (of the antipsychotic medication). How much
medication you are taking (the dose) is very important. For
many people, higher doses control symptoms better. But
higher doses can also cause more side effects.
- Duration. This means how long you’ve been taking
the medication. It usually takes some time for antipsychotic
medications to work. For example, when you switch from one
antipsychotic to another, it can take a couple of months to
find out how well the new medication will work.
- Compliance. For your medication to work, you need
to take it! The medical word for this is compliance.
Even if the medication isn’t perfect, chances are you’ll
have more problems if you stop the medication on your own.
If you feel like stopping the medication, be sure to talk to
your doctor and discuss your feelings. Maybe you and your
doctor can work something out!
Overview of Antipsychotic
Medications
The following tables list the brand names and
generic names of some of the most commonly prescribed
antipsychotic medications in the United States today. You’ll
notice that the antipsychotics are listed in two groups.
Newer antipsychotic medications: The
first group contains the newer antipsychotics. These
medications are sometimes called atypical
antipsychotics. Atypical means something different or unusual.
These medications usually don’t cause the same kinds of side
effects, particularly movement problems, that the older
antipsychotic medications do. The atypicals also seem to work
better on negative symptoms.

|
Geodon |
ziprasidone |
|
Risperdal® |
risperidone |
|
Seroquel® |
quetiapine |
|
Zyprexa® |
olanzapine |
Older antipsychotic medications: The other type
of antipsychotic is called a conventional (typical)
antipsychotic. These medications have been around for a long
time. The oldest one (Thorazine®) has been used since the 1950s. All
the conventional antipsychotics have similar effects on brain
chemistry.

available in long-acting injections (shots), called “depot”
therapy, which are given once or twice a month. Injections can
be helpful for people who have trouble taking pills every
day.

How Are the Atypical Medications
Different?
The older, conventional antipsychotics are more
likely to cause a variety of neurologic side effects that
often make people feel uncomfortable. Because the atypical
medications are less likely to cause the same kinds of side
effects, particularly movement problems, many people feel more
comfortable when they take the atypical medications. While the
newer medications aren’t perfect, their better side effect
picture may make them much easier to take for many people.
What Are the Differences in Side Effects
Between the Atypical and Conventional Medications?
- Atypical medications are less likely to cause
neurologic side effects called extrapyramidal symptoms
(EPS). One of the things doctors know for sure is that
the atypical antipsychotics cause fewer EPS, which affect
normal body movement. EPS include tremor (shakiness), tight
muscles, and joint stiffness. Some kinds of EPS can make
people have very unpleasant sensations, such as feeling
“like a zombie” physically, or they can cause feelings of
restlessness known as akathisia. While EPS can still happen
on the atypical medications, they are much less common and,
when they do happen, they are usually not as bad as with the
old medication.
- With atypical medications, patients are less likely
to need to take side effect medications to counter these
EPS. The medications that are used to treat EPS are
called anticholinergics (an example of this kind of
medication is benztropine [Cogentin ®]). Although anticholinergics are
very good at reducing EPS, they can cause side effects of
their own! Anticholinergics can make it harder to remember
things, or make it harder to pay attention. Being able to go
off of anticholinergic medication may help your memory and
concentration. Anticholinergics can also cause other side
effects like blurry vision, dry mouth, constipation, and
trouble urinating. Be careful—going off of
anticholinergic medication too quickly can cause withdrawal
problems! Don’t stop taking your anticholinergic without
discussing it with your doctor. Most of the time, you should
go off of it SLOWLY!
- The atypical medications may be less likely to cause
tardive dyskinesia (TD) than the conventional
medications. TD is another kind of movement disorder
side effect. TD can cause unusual kinds of mouth, tongue, or
hand movements. It often looks like a kind of wriggling or
writhing. TD usually happens after someone has been on
antipsychotic medication for a long time. Sometimes these
movement problems are permanent. The atypical antipsychotics
appear to be less likely to cause TD.
- Most of the atypical medications do not cause
significant prolactin problems. Prolactin is a hormone
in the bloodstream that comes from a part of the brain known
as the pituitary gland. Some antipsychotic medications can
raise the level of prolactin in the bloodstream. In both men
and women, high prolactin levels can cause sexual problems.
High prolactin levels can stop a woman from having menstrual
periods and can even cause milk to leak from her breasts. In
men, high levels of prolactin may cause enlarged breasts and
a lower sex drive. The good news is that most of the
atypical antipsychotic medications do not increase prolactin
levels enough to cause side effects.
- The atypical antipsychotics cause less sedation or
none at all. The daytime drowsiness caused by the older
medications can be very bothersome. For many people this
side effect goes away after a while. But for other people,
it may not. Some of the newer atypical medications don’t
cause any drowsiness.
What Kinds of Side Effects Do the Atypical
Medications Have?
By now you may be thinking, “If everything’s so
great about the atypical medications, there must be a catch.”
Well, you’re right! All antipsychotic medications,
including the atypical medications, do have side effects. So
it’s not realistic to think that you won’t have any side
effects after you change medication. It’s realistic to hope
that the new medication may not have as many side effects, or
that the side effects may not be as bad. The kinds of side
effects that can happen with the atypical medications are
discussed below.
- The atypical medications can still cause EPS and
TD. While EPS occur less often with the atypical
medications, they haven’t completely disappeared. You can
still have EPS when you take the atypical medications—and
this is more of a problem with some of the atypical
medications than with others. But remember that EPS are much
less likely to happen on the atypical medications. The same
is true for TD. It can still happen, but it is much less
likely with the atypical medications than with the older
ones.
- Some of the atypical antipsychotics can cause
sedation (sleepiness). Both the conventional
antipsychotics and the atypical antipsychotics can make
people feel tired and sleepy. But some of the atypical
medications are much less sedating than other atypical
medications or than conventional antipsychotics.
- Most of the atypical antipsychotics can cause weight
gain. For some people who are underweight, weight gain
can be a good thing. However, most of the time weight gain
is a problem. Unfortunately, most of the atypical
medications cause more weight gain than many of the older,
conventional medications, so some people will gain more
weight when they try an atypical medication. This is more of
a problem with some of the atypical medications than it is
with others. If weight gain is a concern for you, you can
ask your doctor about differences in weight gain caused by
different medications.
It has to be remembered that atypical
anti-psychotics are not all the same. Each one has different
potential side effects. It is also important to remember that
different people experience different side effects.
Top
Switching Medications
What Are Reasons to Switch?
The basic reason to switch medications is that
you or your doctor hopes that the new medication will
be better for you than the one you are taking now. For
example, your doctor might recommend changing antipsychotic
medications to try to find a medication that might be more
helpful in reducing the symptoms of your illness. Or the
doctor may want to try to find a medication that is safer for
you or has fewer bothersome side effects. Of course, you may
not be used to thinking about your problems as “symptoms” or
“side effects,” and that’s OK. Be sure that you and your
doctor talk about these problems and have realistic
expectations.
There are three ways that a new medication might
do a better job for you:
- It might do a better job of keeping you stable and
preventing relapses (keeping you from getting sick again).
- It might do a better job of controlling the day-to-day
symptoms you may have—those that stay with you even if you
are stable and are not relapsing.
- It may have fewer distressing side effects than the
medication you’re taking now.
It is a lot easier to predict what may happen to
your side effects than what will happen to your symptoms if
you change medications. Therefore, on this web page, more time
will be spent discussing how changing medication may change
your side effects.
What Medication Should I Switch To? Old or
New?
Most of the time, the doctor will recommend that
you try one of the atypical antipsychotics. There are only a
few situations in which an older antipsychotic medication
would be recommended first. Your doctor might decide to stay
with the older conventional antipsychotics:
- If you need to be on a long-acting depot medication
(none of the atypical medications are yet available in
long-acting injections).
- If you’ve been on one of the older medications before
and did well and want to go back on a medication that you
know worked for you.
What Benefits Are Possible When You
Switch From an Older Conventional Antipsychotic to an Atypical
Antipsychotic?
- Your EPS are likely to get better. As discussed
earlier, the atypical medications cause fewer EPS than the
older medications and are probably less likely to cause TD.
Therefore, many doctors recommend that their patients try
one of the atypical medications if they want to change
medications. If you have EPS on your older conventional
antipsychotic, the chances are good that your EPS will go
away or get much better on the atypical medication. If you
are changing medications because of EPS, keep in mind that
it will take some time for the EPS to get out of your
system. In fact, if you stop your side effect medications
too soon, EPS can get worse because of withdrawal effects.
It’s uncomfortable if EPS suddenly develop, so most doctors
recommend continuing side effect medications for a while
until the old medication is completely out of your system.
Usually, EPS symptoms get better after about a month on the
atypical medication alone.
- There is less risk of getting TD. Doctors aren’t
100% sure, but there is some research that shows that the
atypical medications are less likely to cause TD.
- Your negative symptoms might get better.
Schizophrenia and other psychotic disorders can cause people
to have negative symptoms. These symptoms are called
“negative” because they refer to a loss of things that
should be there, such as normal emotions and energy. If
someone has negative symptoms, he or she may not have much
energy or motivation and may not be interested in doing
things or interacting with other people socially. One of the
most important differences between the older conventional
antipsychotics and the atypical medications is that the
atypical antipsychotics often do a better job of improving
negative symptoms. Many people with schizophrenia find that
their negative symptoms aren’t quite as bad on the atypical
antipsychotics as when they were on an older medication. It
is important to remember that even the atypical medications
may not totally work for negative symptoms. What might
happen is that your negative symptoms might improve from a
grade C to a grade B. For example, although you may not feel
like running a marathon, you may find that you have more
energy.
- Your positive symptoms might get better.
Schizophrenia and other psychotic disorders also cause
people to have positive symptoms. In this case the
term “positive” refers to distortions in perception and
thinking that occur in people with schizophrenia that others
do not experience. Positive symptoms are often called
psychotic symptoms. They include symptoms like
hallucinations (seeing, hearing, feeling, smelling, tasting
something that doesn’t exist) and delusions (false beliefs
not shared by others). Some people may find that the
atypical antipsychotic medications do a better job of
treating positive (psychotic) symptoms than the older
medications. There is no guarantee that this will happen,
and sometimes the older medications do a better job with
positive symptoms.
- Your cognitive symptoms might improve. When
compared with conventional antipsychotics, the atypical
medications may improve your ability to speak clearly, to
concentrate, and to plan ahead.
- Your mood or outlook might improve. If you are
depressed, your mood or outlook might improve. The atypical
medications seem to be better at improving depressive
symptoms, which are quite common among patients with
schizophrenia.
Top
Switching From One Atypical Antipsychotic
to Another Atypical Antipsychotic
The atypical antipsychotics are different not
only from the conventional antipsychotics, but also from each
other. In addition, the atypical antipsychotics do not work
equally well for all people with schizophrenia. They often
have different effects in different people. So if you are
currently taking one of the newer antipsychotics, use the
report card to see how well it is helping you. If it turns out
that you still have symptoms that bother you or problems with
side effects like weight gain or sedation, you may want to
talk to your doctor about switching to another atypical
medication.
A cautionary note about switching FROM
clozapine TO another antipsychotic
If you are on clozapine, you should know that
many doctors believe that it is harder to switch from
clozapine to another antipsychotic drug because there are more
risks. So if you are taking clozapine and think you would like
to switch to another antipsychotic, please talk to your doctor
about what kinds of problems may occur.
What Are Some Reasons to Stay on My
Current Medication?
There are a number of good reasons for staying
on your current medication. You should stay on your current
medication:
- If you are satisfied with how well you’re doing now
- If none of the side effects from your current medication
really bother you
- If you’ve already changed medications and are doing
better
- If you prefer getting your medication in long-acting
injections (depot therapy)
- If you aren’t willing to go through the hassle of
switching medication (see “The hassle factor” below)
- If you are very worried about the uncertainties of
trying a new medication
- If your doctor thinks you’re better off staying on your
current medication
- If your partner or family member doesn’t want you to
change medication
- If you are about to go through a stressful situation
that would make switching difficult at this time, for
example, starting school or a new job
What’s the Downside of Changing
Medications?
Any major change in your treatment will have its
downside. In medical terms, these are known as risks. The
risks of changing medication can be thought of as
short-term problems and long-term risks.
Short-term problems happen in the first few months after
switching medication and should stop being a problem after
you’ve been on the new medication for a few months. The
long-term risks have to do with the fact that no medication is
guaranteed to be better. It is always possible
that the new medication won’t work well for you or will cause
troublesome side effects.
- The hassle factor. Changing medications can be a
hassle. If you’ve been on your current medication for a
while, you’re used to your medication routine. When you
change medications, it usually means extra visits to the
clinic, pharmacy, or doctor.
Switching often means taking doses of the new
medication while you’re tapering down on your old
medication. You’ll have to be willing to deal with all
the hassle for a while and maybe find someone to help you
deal with it if it is a problem. Just remember that if you
try a new medication and it works for you, pretty soon
things should settle down again and you’ll become used to
your new routine!
Another possible hassle is that your doctor might
need to get some medical tests. You may need medical
tests or you may not need them, depending on the medication
and your own medical history. Your doctor will talk to you
about these issues and review them with you before you
switch.
- The idea of switching can make people nervous.
It’s normal to feel anxious when you try something new. When
people are used to their medication protecting them from
psychotic symptoms, the idea of making a change can make
them very nervous—it can feel like giving up your safety
net. Some people have terrible memories of their last
psychotic episode (relapse or “nervous breakdown”) and have
learned that taking their medication regularly keeps their
symptoms from coming back. You may feel anxious about the
idea of changing medications because you’re worried about
symptoms coming back. There are no guarantees that the new
drug will work better. However, by switching, you may
improve the control of your symptoms or minimize or
eliminate troublesome side effects.
- Sometimes symptoms can come back for a while.
Many people worry about the possibility that their symptoms
may get worse if they change their medication. This is a
realistic concern. Probably the biggest risk in switching
antipsychotic medications is that your symptoms could get
worse. Old symptoms that have been controlled by your
current medication could reappear. Sometimes it might feel
like the changes in medication are shaking up your whole
system. Fortunately, doctors have learned that these kinds
of flare-ups are usually temporary, if they occur at all.
When they do occur, they usually go away with time and
further medication adjustments.
- You may have to deal with new side effects.
Sometimes there are new side effects that occur. Some of
these side effects may show up soon after you start the new
medication, but then go away on their own. The best thing to
do about these temporary side effects is to try to stick
with the medication and wait for the side effect to go away.
For example, a new medication may cause sleep problems at
first. You may feel sleepy during the day or have trouble
sleeping at night (insomnia) for a little while after you
start the new medication. These kinds of effects usually go
away in a few weeks.
Other side effects may not be as likely to go
away. Weight gain is an example of one problem that may
not go away quickly. It turns out that weight gain is more
of a problem with most of the atypical medications than with
most of the older ones. If you are already overweight or
have a medical condition that can get worse if you gain
weight (like diabetes), ask your doctor about how you can
prevent gaining any more weight when you switch medications.
Just keep in mind that not everyone gains weight when they
switch to an atypical medication. Also, some of the newer
atypical antipsychotics cause less weight gain than others.
- There is always the chance that you might be
disappointed. When you switch medications, you and your
doctor hope that you will do better—either by having fewer
symptoms or fewer side effects. This is where the long-term
risks of switching come in. Unfortunately, there isn’t
any guarantee that an atypical medication will work better,
or even as well, for your symptoms. There is a chance
that you might need to go off your new medication because it
isn’t working. Of course, before that happens, your doctor
will want to make sure that you have been taking enough of
the medication for a long enough time. Remember that it
takes some time for any antipsychotic medication to work.
The doctor may also need to change the dose to see if this
will help. Don’t stop your medication on your own, even
if you don’t think it is helping. Talk to your doctor
about what is happening and what might help you do
better.
Overall, the atypical antipsychotic
medications may be safer than the older ones because EPS can
cause serious problems. Atypical antipsychotic medications
cause fewer EPS.

Making the Decisions
Things to Think About
Making decisions about things that affect your
future is tough. People struggle with these kinds of decisions
in all areas of life: Where should I live? Should I go back to
school? Should I change jobs? Of course, no one can make the
decision for you, but there are things to consider when making
a decision about changing medications.
Think about your goals in life. Are there
symptoms or side effects that are keeping you from reaching
your goals?
Think about your ability to accept some risk and
uncertainty. Are you someone who might be willing to take some
chances or are you someone who hates uncertainty?
Finally, think about your priorities right now.
If you decide to switch medications, you will need to make
switching a priority in your life until you’ve gotten used to
the new medication.
Partnering With Your Doctor
It is important for you and your doctor to
consider all parts of your situation and to reach a decision
together.
Be sure to give your doctor all the information
you can about what is going on with your illness and your life
at the moment. For example, let your doctor know if you are
planning any big changes in your life that might make it hard
for you to focus on switching, such as going back to school or
starting a new job. Listen carefully to what your doctor has
to say, too. He or she may have information you have not
thought about or concerns you have not considered. If the
doctor says that now is not the right time for you to switch
medications, be sure you understand why. You and your doctor
can then make a plan for the future. For example, if you are
in the middle of a big change in your life, such as moving,
you and the doctor may decide it would be better to wait for a
while before switching. Or if you have just recently recovered
from a relapse or have only been on your current medication
for a short time, the doctor may suggest waiting a little
longer before trying a different medication.
Getting Ready to Switch
Let’s assume that you and your family have
already met with your doctor and treatment team and have
decided that it’s time to change your medication. You’ve
discussed the pros and cons of each medication and picked the
one you’re going to switch to.
Now it’s time to make the switch! It’s
impossible to know ahead of time exactly how your body and
brain will react to going off your old medication and starting
the new one. While you’re going through this switch, you
need to make it the most important thing in your life—your top
priority. Remember that it only has to be a top priority
for now. You can usually get back to your other priorities in
a few months—you may have to think about postponing other
goals, but not canceling them altogether. Avoid letting other
things get in the way of making a successful switch. The good
news is that most of the short-term problems of switching can
be managed.
Before you make the switch, you and your doctor
will probably make a switching plan that is sometimes called a
“medication crossover.”
Top
Making the Switch
What Is a Medication Crossover?
Your doctor will probably recommend staying on
your old medication for a while rather than going off it “cold
turkey.” Most of the time, you’ll start switching by taking
the new medication along with your old medication. Your doctor
will probably have you slowly raise the dose of the new
medication, while slowly lowering the dose of the old
medication.
This process of overlapping medications is
called a medication crossover. It means that you will
be taking two antipsychotic medications at once for a while.
This is to give the new medication time to “sink in” while the
old one is still working for you. Other reasons for doing a
medication crossover are that it makes it less likely you’ll
have withdrawal reactions from going off your old
medication too quickly and less likely you’ll get bothersome
side effects from your new medication. After a while, the
doctor can decrease your old medication a little at a time.
The hope is that you will be able to stop taking your old
medication and just take the new one without having any
increase in symptoms.
How Long Will It Take for the New
Medication to Work?
There is a delay between the time when you start
a new antipsychotic medication and the time when benefits
start to happen. Generally, it takes about 4 to 6 weeks
after you get to an adequate therapeutic dose for most
antipsychotic medications to begin to help. However, it can
sometimes take as long as a couple of months for some
conditions and some medications. It is as if your brain
chemistry doesn’t really “figure out” that it is receiving a
new medication until then. Unfortunately, this is less true
for side effects— you will often feel the side effects of a
medication before its benefits.
After Switching Medication—Now
What?
In general, it’s best to be cautiously
optimistic when you are trying a new medication—but don’t fall
into the trap of being overconfident that the medication will
work for you. Unless you’ve been on the medication before,
there’s no way to know for sure if a particular medication
will work for you. Another trap is expecting too much from a
new medication. Sometimes a good result will be a
reduction in symptoms rather than having them go away
completely. So if you expect 100% symptom control, you’ll be
disappointed. On the other hand, if you’re sure nothing is
going to work, it’ll be a lot harder to stick with the
medication plan. You might give up too early and miss out on
benefits you might have gotten later on.
How Can I Tell If the New Medication
Is Working?
It is helpful to know ahead of time what you
want the new medication to do. You may want the new medication
to control your symptoms better or you may want it to have
fewer side effects. You can monitor yourself to see if there
has been any change in the level of your target symptoms or
side effects. Be aware that early signs of improvements are
often subtle—they may just appear as a reduction in the
intensity of a symptom or side effect.
It is also important to be cautious about
jumping to conclusions too soon. Everyone has good days and
bad days, and this is true for symptoms as well. It can be
easy to misinterpret a few good days to mean the new
medication is working, or to misinterpret a few bad days to
mean that the new medication is not working. That’s jumping
the gun. It’s more accurate to watch for trends in symptoms
over longer periods of time. It is like the changing of
seasons—you can’t tell from any single day that winter is
changing to spring. Rather, it’s the trend in temperature over
time that really matters!

What If the New Medication Doesn’t Work
for Me?
If the new medication just isn’t working, there
are other things you and your doctor can try. While you are
bound to feel disappointed, don’t become discouraged.
Remember, there are other options that you haven’t tried! Here
are some of the strategies that your doctor might recommend if
a new medication has not worked as well as you hoped it
would:
- Adjusting the dose
- Adding other medicines
- Going back to the medication you were on before trying
this one
- Trying another one of the newer atypical antipsychotics
- Trying one of the older antipsychotics
- Trying a long-acting depot injection if taking oral
medication has been a problem
- Trying clozapine (Clozaril®)
The pros and cons of these options will not be
dealt with here, but you and your partner or family should
discuss them with your doctor or treatment team.
If the new medication has helped your symptoms
but has caused some new side effects, you will need to
consider the pros and cons of staying on the new medication or
trying another new medication.
Be sure to give yourself credit for trying a new
treatment. It takes courage! Even though you didn’t get what
you hoped for, you’ve shown your commitment to trying to get
better. Don’t become discouraged. The next medication you try
may work much better for you.
Coping With Getting Better
You may find that the switch has worked well for
you. You may find that you are doing better in a number of
different ways. You may have more energy, your thinking and
concentration may be better, or you may feel less scared
because of frightening or strange thoughts. Congratulations!
These improvements can help you get more out of your life.
Remember, though, that change can bring new
challenges and stresses. And getting better can be
stressful.
Be aware that you may have some setbacks from
doing better. For example, if you have more energy and start
to get busier, you’ll experience more stress. You may have no
trouble handling this and it will be smooth sailing. But
sometimes stress can bring out the symptoms of
schizophrenia.
The best advice to people who get a lot better
very quickly is to take your time and not rush!
Adapting to an improvement in symptoms is a big challenge in
itself. Give yourself time to adjust and don’t try to take on
too many new things all at once. It is better to move
gradually. Also, try not to be too disappointed if setbacks
happen, and be ready to accept help from others if you need
it.
Final Thoughts
The atypical antipsychotic medications that are
now available are helping many people do better in ways that
were simply not possible with older antipsychotic medications.
But the only way to see whether an atypical medication will be
better for you is to try it. To make sure that you get the
most out of a new medication, you need to give it a chance to
work. This means taking enough of the medication for a long
enough period of time.
Going over the pros and cons of switching
medication can be a very important experience, no matter what
you decide. You’ll learn more about yourself, your goals in
life, and what’s good and bad about the antipsychotic
medication you’re taking now. You’ll also learn about other
options and what’s good and bad about them. May you have very
good luck in finding the very best treatment for you!
