Additional information
If you are 65 years or older, you may experience more side effects while taking Sinemet. This may cause your urine, sweat and saliva to appear dark red, brown or black. This is normal and should not be a cause for concern.
Sinemet can make you feel very sleepy. Some people who take it have fallen asleep while doing important activities such as driving. This can happen for up to 1 year of starting the drug. If you feel the side effects of becoming especially sleepy, do not drive or do other important tasks.
If you have any fever, muscle cramps, stiffness, dizziness, headache, confusion or abnormal heartbeat, call your doctor. Sinemet can sometimes cause a more serious condition called neuroleptic malignant syndrome, which can cause these symptoms.
