things neither normally heard nor seen. This medication will reduce or
stop these experiences and help you remain outside the hospital.
-
This medication cannot "cure" the illness, but it can take
away many of the symptoms or make them milder. It is important to take
this medication as directed, even when you begin to feel better. It is
necessary to continue taking this medication in order to keep feeling well.
When taken regularly, this medication usually requires up to six weeks
before the full effects are noticed.
-
This medication does not produce euphoria (a high feeling)
and is not addictive.

PROBABLE HEALTH CONSEQUENCES OF NOT
TAKING THIS MEDICATION
-
If you elect not to take this medication, it is important
for you to understand the potential consequences. The symptoms of psychosis
will not get better; in fact, they could worsen.
-
When suffering from the symptoms of psychosis, you may "hear
voices" or have strange and untrue ideas.
-
You may get excited for no apparent reason, or spend a lot
of time off by yourself, or in bed, sleeping during the day and staying
awake at night.
-
You may neglect your appearance, and may become difficult
to communicate with--saying things that make no sense, or barely talking
at all.
-
These symptoms may lead to difficulty with your job, or relationships
with your family and friends, or day-to-day functioning.
-
Left untreated, psychosis also could lead to thoughts or
attempts of harming oneself or others.
ALTERNATIVE TREATMENTS
-
Other antipsychotic medications: "typical neuroleptics" such
as chlorpromazine or haloperidol, or "atypical neuroleptics" such as risperidone.
-
"Depot" injectable typical antipsychotic medications.
-
Electroconvulsive therapy.
-
Support groups, as an adjunct to medication, are often helpful
in providing support, education, and guidance; however, they do not
replace medication.
PROPER USE OF THIS MEDICATION
-
While you are on clozapine, you must be carefully monitored
because clozapine can cause a severe reduction in your body's ability to
make white blood cells (agranulocytosis). This happens in 1 or 2 people
out of every 100 who receive clozapine. If this happens, it could result
in your body not being able to fight off infection. This could lead to
a severe infection, getting very sick, being put into a general hospital
and possibly death.
-
For this reason you will have a blood test every week while
you are taking clozapine. This test is designed to detect any changes in
the number of your white blood cells BEFORE any problems occurs.
If you do not get your blood drawn, medications will not be prescribed.
-
If you need to travel or if you cannot keep an appointment,
other arrangements can be made. After you stop taking clozaril, we will
continue to draw your blood once weekly for four weeks to make sure everything
is okay. You can also help monitor your white blood cell counts by informing
your doctor of any signs of infection, which you might have. It is most
important to call right away if you have a fever, or feel like you are
getting "the flu", have a sore throat, notice unusual bleeding, or notice
you are getting little sores or ulcers on any part of your body or in your
stomach.
-
Take with food to lessen stomach upset.
-
Do not take more of this medicine and do not take it more
often than your physician has prescribed.
-
Store medicine away from heat and direct light. Keep out
of the reach of children. Do not store in the bathroom medicine cabinet
since heat and moisture may cause medicine to break down.
SIDE EFFECTS
-
Drowsiness--this is usually a problem only during
the first few days when you start taking the medication or when you adjust
the dose. Most of the time, this tiredness goes away as you adjust with
time. Until you adjust to this medication, be very cautious driving or
performing tasks that require alertness or coordination.
-
Dizziness, lightheadedness, reduced blood pressure--may
occur when you get up too quickly or change positions rapidly. This occurs
most frequently when clozapine is first started or after the dose is increased.
This can be avoided by rising or changing positions slowly.
-
Increased in heart rate, blood pressure--can cause
your heart to beat faster than normal or your blood pressure to go up.
While this is not usually dangerous, it can sometimes be a problem in certain
people who already have heart problems. If you notice your heart beating
faster or differently, it is important to tell your doctor.
-
Drooling--can cause some people to drool or have a
very wet mouth. If this becomes a problem for you discuss it with your
doctor.
-
Weight gain--may occur in some patients while taking
this medication. If this is not desired, exercise and dietary restriction
may be helpful.
-
Temporary high fever--in the first several weeks of
taking clozapine you may experience a high fever for a day or two. Often
this fever may just be bothersome and not dangerous. However, the fever
could be a sign of a blood problems, so it is very important that you tell
your doctor as soon as possible.
-
Seizures, convulsions--Clozapine can cause seizures
or convulsions in some patients. The changes of having a seizure while
taking clozapine get higher as the dose goes higher. Because a person passes
out during the seizures caused by clozapine, you should avoid driving,
working with machinery or similar dangerous activities until your dose
of clozapine has stay the same for several weeks. If you have a seizure,
notify your physician.
-
Neuroleptic Malignancy Syndrome--A rare but potentially
fatal side effect that has occurred with antipsychotic medications symptoms
includes very high fever, muscle stiffness and confusion, irregular heartbeat
and sweating. If these symptoms occur seek immediate medical attention.
Individuals who have had a heatstroke maybe at greater risk for this condition.
PRECAUTIONS
-
Do not drink alcoholic beverages while taking antipsychotics.
-
Do not stop taking this medication before checking with your
doctor. Because people respond to medicines in very individual ways, you
and your physician may have to go through a trial period to find the right
drug and dosage that work best for you.
-
Before taking this medication, tell your physician what prescription
and non-prescription medications you are taking (or have taken recently).
Do not begin taking prescription or non-prescription medication without
consulting your physician.
-
Female patients: notify your doctor if you think you are
pregnant, if you want to become pregnant, or if you are breastfeeding while
taking this medication.
-
Avoid direct exposure to sunlight while taking this medication,
because this medication may cause your skin to be more sensitive to sunlight
than it is normally. If you must be out in the sun, wear protective clothing,
including a hat, and sunglasses. Apply a sun block product that has a skin
protection factor (SPF) of at least 15.
-
This medication will often make you sweat less, causing your
body temperature to increase. Use extra care not to become overheated during
exercise or hot weather while you are taking this medicine, since overheating
may result in heat stroke.
-
Smoking increases the metabolism of this medication leading
to unpredictable or diminished drug effects. It is best not to smoke; but
if you do smoke, frequent monitoring of the medications clinical effects
is necessary.
