IMPORTANT DRUG INFORMATION

16-April-2003

Dear Healthcare Provider,

Janssen Pharmaceutica Products, L.P., would like to inform you of important changes regarding RISPERDAL (risperidone). The RISPERDAL prescribing information has been updated with the addition of the following information:

WARNINGS
Cerebrovascular Adverse Events, Including Stroke, in Elderly Patients with Dementia
Cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, were reported in patients (mean age 85 years; range 73-97) in trials of risperidone in elderly patients with dementia-related psychosis. In placebo-controlled trials, there was a significantly higher incidence of cerebrovascular adverse events in patients treated with risperidone compared to patients treated with placebo. RISPERDAL has not been shown to be safe or effective in the treatment of patients with dementia-related psychosis.

This update is based on data from 4 placebo-controlled trials conducted in elderly patients with dementia (N=1230). Additional information on these and other clinical trials conducted in elderly patients can be obtained by calling 1-800-JANSSEN (800-526-7736). We remind you that, like all other antipsychotics, RISPERDAL is not indicated for the treatment of dementia.

Janssen Pharmaceutica Products, L.P., remains committed to providing you with the most current product information available for the management of your patients. Please refer to the enclosed package insert for full prescribing information. As always, we request that serious adverse events be reported to Janssen at 1-800-JANSSEN (526-7736) or to the FDA MedWatch program by phone 1-800-FDA-1088, by fax
(1-800-FDA-0178), or by email (www.fda.gov/medwatch). For additional medical information about RISPERDAL or any other Janssen product, please call 1-800-JANSSEN (526-7736) from 9AM to 5PM EST, Monday through Friday.

Sincerely,

Christine Cote, MD
