Tasmar Patient Information Including Side Effects

Brand Names: Tasmar

Generic Name: tolcapone (Pronunciation: TOLE ka pone)

What is tolcapone (Tasmar)?

When used with carbidopa and levodopa (Atamet, Parcopa, Sinemet), tolcapone increases levels of levodopa in the body.

Tolcapone is used together with carbidopa and levodopa to treat symptoms of Parkinson's disease, such as stiffness, tremors, muscle spasms, and poor muscle control.

This medication is usually reserved for use only in people who have used carbidopa and levodopa without success in treating their Parkinson's disease.

Tolcapone is usually given to people who are already taking carbidopa and levodopa but have not had successful treatment of symptoms.

Tolcapone may also be used for other purposes not listed in this medication guide.
