There are three types of Parkinson's disease, each with its own side effects: dopamine agonists carbidopa/levodopa and COMT inhibitors, states Everyday Health. Dopamine agonsits, which mimic the dompamine that the nerves in the brain are supposed to produce, can cause chest and abdominal pain, trouble sleeping or particularly vivid dreams, and risky behavior. Some of this risky behavior includes compulsive gambling and can be harmful. Those who are experiencing it need to contact a medical professional and have the dosage changed or the medication discontinued.

Sinemet, a medication that include the drugs of carbidopa and levodopa, can cause involuntary movements and writhing, states Everyday Health. However, this side effect doesn't usually manifest for a few years and can be mild in some patients. After prolonged use, the drug can be less efficient, requiring dosage changes or the addition of another medication.

COMT inhibitors can cause diarrhea and even liver failure in patients who use it, notes Everyday Health. Those using this medication need to get their blood monitored regularly to ensure that the liver is still functioning well.
