Generic Sinemet is used to treat Parkinson symptoms such as muscle stiffness, tremors, spasms, and poor muscle control. This medication is also used to treat Parkinson symptoms caused by carbon monoxide poisoning or manganese intoxication.
The active ingredient in Generic Sinemet, Levodopa is converted to dopamine via the action of a naturally occurring enzyme called DOPA decarboxylase. This occurs both in the peripheral circulation and in the central nervous system after levodopa has crossed the blood brain barrier. Activation of central dopamine receptors improves the symptoms of Parkinson's disease.
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Generic Sinemet can be taken with or without food. Take your doses at regular intervals to keep a steady amount of the drug in your body at all times.
Do not crush, chew, or break an extended-release tablet. Swallow the pill whole. Breaking or opening the pill may cause too much of the drug to be released at one time.
The regular tablet can be broken or crushed if needed to make it easier to swallow.
To take the orally disintegrating tablet:
- Keep the tablet in its blister pack until you are ready to take the medicine. Open the package and peel back the foil from the tablet blister. Do not push a tablet through the foil or you may damage the tablet.
- Using dry hands, remove the tablet and place it in your mouth. It will begin to dissolve right away.
- Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. Swallow several times as the tablet dissolves.

These things can make it harder for your body to digest and absorb carbidopa and levodopa.
