Catechol-O-methyl transferase (COMT) is a medication that deactivates levodopa prior to it being absorbed in the bloodstream to get to the brain. This medication can increase the benefit of levodopa, reducing "off" times and lengthening "on" times. They are generally well tolerated, though they may exaggerate some levodopa-related side effects, particularly dyskinesia. Additional side effects may include:
Discoloration of Urine
