For TASMAR Patients


When you or a loved one is started on TASMAR® (tolcapone), there are a few things you should know. In this section, explore all the things you should know when you or a loved one begins TASMAR therapy.

TASMAR is usually prescribed when Parkinson’s patients are no longer getting an adequate response from other treatments, called wearing off. When this happens, the symptoms of Parkinson’s can reappear, including tremors, slurred speech, and difficulty walking, just to name a few. TASMAR can help improve these Parkinson’s symptoms.

TASMAR SHOULD NOT BE USED BY PATIENTS UNTIL THERE HAS BEEN A COMPLETE DISCUSSION OF THE RISKS AND THE PATIENT HAS PROVIDED WRITTEN INFORMED CONSENT (SEE PATIENT ACKNOWLEDGEMENT FORM).

WARNING: Because of the risk of potentially fatal, acute fulminant liver failure, TASMAR (tolcapone) should ordinarily be used in patients with Parkinson's disease on l-dopa/carbidopa who are experiencing symptom fluctuations and are not responding satisfactorily to or are not appropriate candidates for other adjunctive therapies (see INDICATIONS and DOSAGE AND ADMINISTRATION sections).

TASMAR therapy should not be initiated if the patient exhibits clinical evidence of liver disease or two SGPT/ALT or SGOT/AST values greater than the upper limit of normal. Patients with severe dyskinesia or dystonia should be treated with caution (see PRECAUTIONS: Rhabdomyolysis).

Laboratory Tests: Although a program of frequent laboratory monitoring for evidence of hepatocellular injury is deemed essential, it is not clear that periodic monitoring of liver enzymes will prevent the occurrence of fulminant liver failure. However, it is generally believed that early detection of drug-induced hepatic injury along with immediate withdrawal of the suspect drug enhances the likelihood for recovery. Accordingly, the following liver monitoring program is recommended.
