Ziprasidone is an atypical antipsychotic.
It works by blocking dopamine (D2) and serotonin (5-HT2A) receptors in the brain, helping to balance neurotransmitter levels. This action reduces symptoms of schizophrenia and bipolar disorder, such as hallucinations and mood swings. It also affects other receptors, contributing to its mood-stabilizing and antipsychotic effects.

Ziprasidone is available as oral capsules to take by mouth. These are available in a variety of strengths.
The use of Ziprasidone is meant for adults.
It can also be administered to children, but only under the specific advice and supervision of a doctor.
The use of Ziprasidone is contraindicated in patients with known hypersensitivity to the medication or any of its components.
It should also not be used by patients who are at high risk of experiencing torsades de pointes, a specific type of abnormal heart rhythm.
Ziprasidone may interact with medicines known to prolong the QTc interval, such as Class 1A and Class III antiarrhythmic medications (like amiodarone and dofetilide), certain other antipsychotics (like thioridazine), and specific antibiotics (like gatifloxacin).
The medicine should also be used cautiously with other centrally acting medicines like diazepam, as these may result in additive CNS effects.
An overdose of Ziprasidone can lead to severe complications like neuroleptic malignant syndrome, a life-threatening condition characterised by fever, confusion, severe muscle stiffness, and fluctuations in blood pressure. If you suspect an overdose, consult a doctor immediately.
In case of a missed dose, take it as soon as you remember. However, if it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule.
Most side effects are temporary and generally harmless and resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of any of the symptoms, please consult your doctor. Here are some tips to manage common side effects:
For symptoms like nausea and vomiting, try taking the medicine after meals.
If you experience dizziness or light-headedness, avoid sudden movements and rise slowly from a sitting or lying position.
Ensure you stay well-hydrated to help alleviate constipation.
