These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What side effects may I notice from taking tolcapone?

Side effects that you should report to your prescriber or health care professional as soon as possible:

  • abdominal pain
  • anorexia or loss of appetite
  • confusion
  • fainting spells or lightheadedness

  • dizziness
  • drowsiness
  • dry mouth
  • fatigue
  • headache
  • increased sweating
  • muscle cramping
  • nausea
  • upset stomach

What should I watch for while taking tolcapone?

Tolcapone may also increase the side effects caused by levodopa-carbidopa such as nausea or restless movements. If you notice an increase in or the appearance of certain side effects that occurred only while you were taking levodopa-carbidopa, contact your physician. The dose of levodopa-carbidopa may need to be lowered.

Visit your prescriber or health care professional for regular checks on your progress. Your health care professional will need to frequently monitor blood tests to check the effects of tolcapone on the function of your liver. In rare cases tolcapone has caused liver injury. Your health care professional will monitor you closely and will want any unusual side effects reported to them as soon as possible. It may be several weeks before you feel the full effect of tolcapone. Continue to take your medicine on a regular schedule and do not stop taking except on your prescriber's advice.

You may get dizzy or have difficulty controlling your movements. Do not drive, use machinery, or do anything that needs mental alertness until you know how tolcapone affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can increase possible dizziness; avoid alcoholic drinks.

If you are going to have surgery, tell your prescriber or health care professional that you are taking tolcapone.

Tolcapone may make your mouth dry. Chewing sugarless gum, sucking hard candy and drinking plenty of water may help. Visit your dentist regularly.
