About Ziprasidone

Ziprasidone is an atypical antipsychotic. The capsules are labeled for adults with schizophrenia, for manic or mixed episodes of bipolar I disorder, and for long-term bipolar I treatment added to lithium or valproate; it is not established in children. Schizophrenia treatment usually starts at 20 mg twice a day, adjusted up to 80 mg twice a day; mania starts at 40 mg twice a day, raised to 60 or 80 mg twice a day on day two. Food can up to double absorption, so the capsules are taken with a meal and swallowed whole. The injection treats acute agitation in schizophrenia at 10 mg every two hours or 20 mg every four hours, up to 40 mg a day, and capsules replace it as soon as possible.

The boxed warning says older adults with dementia-related psychosis treated with antipsychotics have a higher risk of death, and ziprasidone is not approved for them. It prolongs the QT interval, so it must not be used with a history of QT prolongation (including congenital long QT syndrome), after a recent heart attack, with uncompensated heart failure, or with other QT-prolonging drugs such as dofetilide, sotalol, quinidine, thioridazine, pimozide or certain fluoroquinolone antibiotics. Low potassium or magnesium is corrected first in people at risk, it is stopped if the QTc stays above 500 msec, and dizziness, palpitations or fainting call for a heart check. DRESS (drug reaction with eosinophilia and systemic symptoms) and other severe skin reactions can be fatal, so a rash with fever or swollen glands needs prompt care. Other warnings include neuroleptic malignant syndrome, tardive dyskinesia, weight and blood sugar changes, low white cell counts, seizures, raised prolactin, prolonged erections and overheating. Sleepiness is common, and in mania so are movement effects, restlessness and dizziness.

A January 2025 label update added serotonin syndrome to the warnings and made MAO inhibitors a contraindication: it is not combined with one, including linezolid or intravenous methylene blue, or started within 14 days of stopping one, and an MAO inhibitor for a psychiatric condition waits at least three days after ziprasidone stops; generic labels have followed. Babies exposed late in pregnancy can have movement or withdrawal symptoms after birth. The Orange Book lists Geodon capsules and Geodon for injection as marketed and Geodon oral suspension as discontinued.

Taking Ziprasidone

How to take it

Twice a day with a meal, swallowed whole; do not open, crush or chew the capsules. Get up slowly, avoid overheating and dehydration, and do not drive until you know how it affects you. The injection is given only by a health professional.

If you miss a dose

Take it as soon as you remember, unless it is almost time for the next dose; then skip the missed dose. Do not take a double dose.

Storage

At room temperature, away from light, heat and moisture, out of reach of children. Use a take-back program rather than flushing it.

Interactions to know about

It is not combined with other QT-prolonging drugs or with MAO inhibitors, and other serotonin-affecting medicines add to the risk of serotonin syndrome. Carbamazepine lowers its levels and ketoconazole raises them; it adds to the effect of blood pressure medicines and works against levodopa and dopamine agonists. Avoid alcohol.

This summarizes the official prescribing information. Your prescriber’s and pharmacist’s instructions, and the leaflet that comes with your medicine, take priority.

Why the cash price for Ziprasidone differs from pharmacy to pharmacy

Generic ziprasidone capsules come from several manufacturers, so quotes differ mostly by the pharmacy’s fee and markup, and a prescription that names Geodon and blocks substitution is filled at the brand price. Twice-daily dosing makes a month’s supply a larger count. The injection is given by a health professional, so it is not part of a take-home fill.

Ways to pay less for Ziprasidone without insurance

• Ask for generic substitution, and make sure the prescription does not block it.
• Ask whether ziprasidone is on the pharmacy’s flat-price generic list, and compare more than one pharmacy.
• Make sure each dose is one capsule of the right strength, for example one 60 mg capsule rather than a 40 mg plus a 20 mg.
• Ask for a ninety-day supply once your dose is stable; it is not a controlled substance.
• Upload the prescription to Script Unlock so licensed pharmacies can quote their cash price. You pay the pharmacy directly.
