KARDOPAL (SINEMET) INDICATIONSLevodopa is converted to a chemical called dopamine (DOE pa meen) in the brain. Symptoms of Parkinson's disease may be caused by low levels of dopamine in the brain.
Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect.
The combination of carbidopa and levodopa 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.
Carbidopa and levodopa may also be used for other purposes not listed in this medication guide.
KARDOPAL (SINEMET) INSTRUCTIONS
If you are already taking levodopa (Larodopa, Dopar), you must stop taking it at least 12 hours before you start taking carbidopa and levodopa.
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.
Carbidopa and levodopa 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.
The regular tablet can be broken or crushed if needed to make it easier to swallow.
To take the orally disintegrating tablet (Parcopa):
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.
To be sure this medicine is helping your condition and is not causing harmful effects, your blood will need to be tested often. Your heart, liver, and kidney function may also need to be tested. Visit your doctor regularly.
This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using carbidopa and levodopa.
