Pfizer Inc's antipsychotic Geodon and generic versions of the drug can trigger a potentially fatal skin reaction, the U.S. Food and Drug Administration warned on Thursday.
A new warning has been added to the drug's label to describe the condition - known as Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) - which may start as a rash and spread all over. (1.usa.gov/1Gh2I8p)
Other symptoms include fever, swollen lymph nodes and organ inflammation.
Geodon, known generically as ziprasidone, is used to treat schizophrenia and bipolar I disorder by reducing hallucinations, delusions and other psychotic symptoms.
While no deaths have been reported, the regulator reviewed six cases in whom the signs and symptoms of D.R.E.S.S. appeared between 11 and 30 days after ziprasidone treatment was initiated.
Last year, 2.5 million prescriptions for oral formulations of ziprasidone were dispensed, the agency said.
Patients on the drug who have a fever with a rash and/or swollen lymph glands should seek urgent care, the regulator said, advising doctors to halt treatment if they suspect D.R.E.S.S.

This testimony may help anyone whose relation have Schizophrenia: My son of 28 years old is always confused, incoherent and childish in behaviour, repeating everything said to him. After years of treatment, using numerous Western medicine (Clozapine, Geodon, Seroquel, Risperdal, Zyprexa, Abilify) without any improvement. I found a better medicine that work effectively in all cases of psychosis. The medicine is liquid and herbal made. It may also improve victim's health as well and does have any negative effect, my son is now back to his work with beautiful kids. Do not be discourage.
