Hi !

Adding carbidopa to "levodopa "does not reduce the incidence of dyskinesias or psychosis. In fact, "carbidopa "can increase the intensity and the speed of onset of these effects.

"Carbidopa" inhibits decarboxylation of "levodopa" in the intestine and peripheral tissues, leading to more levodopa in the CNS.
