TOLCAPONE - ORAL

(TOLL-cup-own)

COMMON BRAND NAME(S): Tasmar

WARNING: Rarely, tolcapone has caused a severe (sometimes fatal) liver problem (liver failure). Tolcapone should not be used if you have even mild liver disease. You should only use tolcapone if you are experiencing problems with your levodopa wearing off between doses. If you show no benefit from tolcapone after 3 weeks of using it, your doctor may choose to stop it.

Before and during treatment with tolcapone, you will have certain blood tests (liver function tests) every few weeks to monitor for liver problems. Keep all medical and lab test appointments. Tell your doctor immediately if you experience symptoms of liver problems (such as persistent nausea/vomiting, abdominal pain, dark urine, severe tiredness, loss of appetite, itchiness). If you experience liver problems from taking tolcapone, you should not take it again.

Your doctor may ask you to sign a consent form after telling you about the possible side effects of this medication.

USES: This medication is used with other medications (levodopa/carbidopa) to treat Parkinson's disease. Tolcapone belongs to a class of drugs known as COMT inhibitors. Many people taking levodopa for Parkinson's have problems with the effects of the levodopa wearing off between scheduled doses, causing symptoms to return or worsen. Tolcapone blocks a certain natural substance (COMT enzyme) that breaks down levodopa in the body. This effect allows the levodopa to last longer in the system so that it doesn't wear off before the next dose.

HOW TO USE: Take this medication by mouth with or without food, usually 3 times daily or as directed by your doctor. You will start on a low dose. Your doctor may increase your dosage after 3 weeks if he or she thinks that you will benefit from a higher dose.

Dosage is based on your medical condition and response to therapy.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not suddenly stop taking this medication unless instructed to do so by your doctor. Doing so may cause your Parkinson's symptoms to become much worse.

Tell your doctor if your condition persists or worsens (such as your Parkinson's symptoms are not controlled).
