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 Tasmar
Take this medication by mouth with or without food as directed by your doctor, usually 3 times daily. You will start on a low dose. Your doctor may increase your dosage after 3 weeks if your doctor 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 lasts or gets worse (such as your Parkinson's symptoms are not controlled).
See also Warning section.
Nausea/vomiting, unwanted/uncontrolled movements, diarrhea, headache, drowsiness, dizziness, lightheadedness, trouble sleeping, increased number of dreams, increased sweating, dry mouth, gas, and abdominal pain may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: easy bleeding/bruising, chest pain, fast/irregular heartbeat, fever, mental/mood changes (such as agitation, confusion, hallucinations), unusual strong urges (such as increased gambling, increased sexual urges), muscle pain/soreness/stiffness/weakness, pain/trouble with breathing.
Some people taking tolcapone have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with tolcapone even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

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 right away if you experience symptoms of liver problems (such as nausea/vomiting that doesn't stop, 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.
