This medication is used to treat certain mental/mood
disorders (such as schizophrenia, bipolar disorder). Ziprasidone belongs to
a class of drugs known as atypical antipsychotics. It works by helping to
restore the balance of certain natural substances in the
brain.
This section contains uses of this drug that are not
listed in the approved professional labeling for the drug but that may be
prescribed by your health care professional. Use this drug for a condition
that is listed in this section only if it has been so prescribed by your
health care professional.
This drug may also be used in combination with other
medication for depression.

This drug may rarely make your blood sugar rise, which
can cause or worsen diabetes. Tell your doctor right away if you have
symptoms of high blood sugar such as increased thirst/urination. If you
already have diabetes, check your blood sugar regularly as directed and
share the results with your doctor. Your doctor may need to adjust your
diabetes medication, exercise program, or diet.

- fainting
- seizures
- signs of liver damage (such as nausea/vomiting that doesn't
stop, loss of appetite, stomach/abdominal pain, yellowing
eyes/skin)
This medication may increase serotonin and rarely cause
a very serious condition called serotonin syndrome/toxicity. The risk
increases if you are also taking other drugs that increase serotonin, so

Ziprasidone may cause a condition that affects the heart
rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely
fatal) fast/irregular heartbeat and other symptoms (such as severe
dizziness, fainting) that need medical attention right
away.
The risk of QT prolongation may be increased if you have
certain medical conditions or are taking other drugs that may cause QT
prolongation. Before using ziprasidone, tell your doctor or pharmacist of
all the drugs you take and if you have any of the following
conditions:
- certain heart problems (heart failure, recent heart attack,
slow heartbeat, QT prolongation in the EKG)
- family history of certain heart problems (QT prolongation in
the EKG, sudden cardiac death)
Low levels of potassium or magnesium in the blood may
also increase your risk of QT prolongation. This risk may increase if you
use certain drugs (such as diuretics/"water pills") or if you have
conditions such as severe sweating, diarrhea, or vomiting. Talk to your
doctor about using ziprasidone safely.
This drug may make you dizzy or drowsy. Alcohol or
marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use
machinery, or do anything that needs alertness until you can do it safely.
Avoid alcoholic beverages. Talk to your doctor if you are using marijuana
(cannabis).
Before having surgery, tell your doctor or dentist about
all the products you use (including prescription drugs, nonprescription
drugs, and herbal products).
This medication may make you sweat less, making you more
likely to get heat stroke. Avoid doing things that may cause you to
overheat, such as hard work or exercise in hot weather, or using hot tubs.
When the weather is hot, drink a lot of fluids and dress lightly. If you
overheat, quickly look for a place to cool down and rest. Get medical help
right away if you have a fever that does not go away, mental/mood changes,
headache, or dizziness.
Older adults may be more sensitive to the side effects
of this drug, especially drowsiness, dizziness, lightheadedness,
uncontrolled movements, and QT prolongation (see above). Drowsiness,
dizziness, and lightheadedness can increase the risk of
falling.
During pregnancy, this medication should be used only
when clearly needed. Babies born to mothers who have used this drug during
the last 3 months of pregnancy may rarely develop symptoms including muscle
stiffness or shakiness, drowsiness, feeding/breathing difficulties, or
constant crying. If you notice any of these symptoms in your newborn
especially during their first month, tell the doctor right
away.
Since untreated mental/mood problems (such as
schizophrenia, bipolar disorder, depression) can be a serious condition, do
not stop taking this medication unless directed by your doctor. If you are
planning pregnancy, become pregnant, or think you may be pregnant,
immediately discuss with your doctor the benefits and risks of using this
medication during pregnancy.
It is unknown if this drug passes into breast milk.
Because of the possible risk to the infant, breastfeeding is not
recommended while using this drug. Consult your doctor before
breastfeeding.
Drug interactions may change how your medications work
or increase your risk for serious side effects. This document does not
contain all possible drug interactions. Keep a list of all the products you

The risk of serotonin syndrome/toxicity increases if you
are also taking other drugs that increase serotonin. Examples include
street drugs such as MDMA/ "ecstasy," St. John's wort, certain
antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such
as duloxetine/venlafaxine), among others. The risk of serotonin
syndrome/toxicity may be more likely when you start or increase the dose of
these drugs.
Taking MAO inhibitors with this medication may cause a
serious (possibly fatal) drug interaction. Do not take any MAO inhibitors
(isocarboxazid, linezolid, metaxalone, methylene blue, moclobemide,
phenelzine, procarbazine, rasagiline, safinamide, selegiline,
tranylcypromine) during treatment with this medication. Most MAO inhibitors
should also not be taken for two weeks before and aftertreatment with this
medication. Ask your doctor when to start or stop taking this
medication.
Many drugs besides ziprasidone may affect the heart
rhythm (QT prolongation), including amiodarone, dofetilide, moxifloxacin,
pimozide, procainamide, quinidine, sotalol, tacrolimus, thioridazine, among
others.
Tell your doctor or pharmacist if you are taking other
products that cause drowsiness such as opioid pain or cough relievers (such
as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or
anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such
as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine,
diphenhydramine).
Check the labels on all your medicines (such as allergy
or cough-and-cold products) because they may contain ingredients that cause
drowsiness. Ask your pharmacist about using those products
safely.
