Tasmar for Parkinson's
Tasmar® (tolcapone) is a prescription drug that is not typically the first choice of treatment for Parkinson's disease. This is due to the risk of potentially fatal liver failure that is sometimes caused by the medication. Tasmar is generally not used unless the available alternatives are ineffective or unsuitable for some other reason.
This medication is always used in combination with carbidopa-levodopa products (Sinemet®, Sinemet CR, or Parcopa®), as it is not effective at treating Parkinson's disease without the use of levodopa. Tasmar is useful for people who experience otherwise uncontrollable fluctuations in their symptoms, such as "wearing off" of their carbidopa-levodopa before each dose.
