Patient Information
Carbidopa is used with levodopa to treat Parkinson's disease. Parkinson's disease
is believed to be related to low levels of a chemical called dopamine (DOE pa meen)
in the brain. Levodopa (Dopar, Larodopa) is turned into dopamine in the body.
Carbidopa is used with levodopa to prevent the breakdown (metabolism) of levodopa
before it can reach the brain and take effect. Carbidopa is only effective if it is
taken with levodopa. It has no effect if it is used alone. Carbidopa is used with
levodopa to treat the stiffness, tremors, spasms, and poor muscle control of
Parkinson's disease. These medications are also used to treat the same muscular
conditions when they are caused by drugs such as chlorpromazine (Thorazine),
fluphenazine (Prolixin), perphenazine (Trilafon), and others.
