SINEMET ( 25mg of Carbidopa and 250mg of Levodopa ) is a controlled-release tablet that may be given to help
relieve the muscle stiffness, tremor, and weakness caused by Parkinson's
disease. It may also be given to relieve Parkinson-like symptoms caused
by encephalitis (brain fever), carbon monoxide poisoning, or manganese
poisoning.SINEMET ( 25mg of Carbidopa and 250mg of Levodopa ) contains two drugs, carbidopa and levodopa. The
drug that actually produces the anti-Parkinson's effect is levodopa.

to work more efficiently.

but are not a permanent cure.

Cardiovascular or lung disease (severe)
Endocrine (glandular) disorder

twitching, jerking, or writhing--sooner and at a lower dosage than
levodopa alone or even regular Sinemet. If such involuntary movements
develop while you are taking SINEMET ( 25mg of Carbidopa and 250mg of Levodopa ), you may need a dosage reduction.

stomach acid can interfere with absorption of the medication.
