Common side effects of Sinemet include upset stomach, nightmares, constipation, dizziness, dry mouth, headache and insomnia.

Your copay and deductible costs for any prescription drug can vary depending on what coverage stage you’re in.
|Deductible stage||Typical copay stage|
|Your deductible is the amount of money you must spend on covered drugs before your Medicare drug coverage starts paying its share of costs.
In the deductible stage, you’re responsible for the full cost of your prescription drugs.
Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $415 in 2019.
|After you meet your Part D deductible, you enter the initial coverage period.
During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.

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.
