Dizziness, drowsiness, weakness, nausea, vomiting, runny nose, and cough may
occur. If any of these effects persist or worsen, notify your doctor or pharmacist
promptly.
Remember that your doctor has prescribed this medication because he or she has
judged that the benefit to you is greater than the risk of side effects. Many
people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects
occur: severe/persistent dizziness, fainting, mental/mood changes (e.g., agitation,
anxiety, depression, suicidal thoughts), feelings of restlessness, mask-like
facial expression (pseudoparkinsonism), shakiness (tremors), muscle spasm/stiffness,
numbness/tingling, trouble swallowing, vision problems, difficulty walking.
Seek immediate medical attention if any of these rare but very serious side
effects occur: chest pain, jaw/left arm pain, slow/fast/irregular heartbeat,
seizures.
This drug may rarely cause a condition known as tardive dyskinesia. In some
cases, this condition may be permanent. Tell your doctor immediately if you
develop any unusual uncontrolled movements (especially of the face, mouth, tongue,
arms or legs).
This medication may rarely cause a very serious condition called serotonin syndrome.
The risk may increase when this medication is used with certain other drugs
such as "triptans" used to treat migraine headaches (e.g., sumatriptan,
eletriptan), certain antidepressants including SSRIs (e.g., citalopram, paroxetine)
and SNRIs (e.g., duloxetine, venlafaxine), lithium, tramadol, tryptophan, or
a certain drug to treat obesity (sibutramine). Before taking this drug, tell
your doctor if you take any of these medications. Seek immediate medical attention
if you develop some of the following symptoms: hallucinations, unusual restlessness,
loss of coordination, fast heartbeat, severe dizziness, unexplained fever, severe
nausea/vomiting/diarrhea, twitchy muscles.
Medications used for a similar purpose to ziprasidone may infrequently cause
a serious (rarely fatal) nervous system disorder called neuroleptic malignant
syndrome (NMS). Seek immediate medical attention if you notice any of the following
rare but very serious side effects: confusion, fever, fast heartbeat, muscle
stiffness, increased sweating.
In rare instances, this medication may increase your level of a certain chemical
made by the body (prolactin). For females, this increase in prolactin may result
in unwanted breast milk, missing/stopped periods, or difficulty becoming pregnant.
For males, it may result in decreased sexual ability, inability to produce sperm,
or enlarged breasts. If you develop these symptoms, tell your doctor immediately.
For males, in the very unlikely event you have a painful or prolonged erection
lasting 4 or more hours, stop using this drug and seek immediate medical attention,
or permanent problems could occur.
A very serious allergic reaction to this drug is unlikely, but seek immediate
medical attention if it occurs. Symptoms of a serious allergic reaction may
include: rash, itching, swelling, severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects
not listed above, contact your doctor or pharmacist.
