Comtess (Entacapone) Tablets
What Is Entacapone?
When used with carbidopa and levodopa (Atamet, Parcopa, Sinemet), entacapone increases levels of levodopa in the body.
Entacapone is used together with carbidopa and levodopa to treat "wearing-off" symptoms of Parkinson's disease, such as stiffness, tremors, muscle spasms, and poor muscle control.
Entacapone may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
You should not use entacapone if you are allergic to it.
To make sure entacapone is safe for you, tell your doctor if you have:
- low blood pressure;
- liver disease; or
- a history of mental illness or psychosis.
You may have increased sexual urges, unusual urges to gamble, or other intense urges while taking this medicine. Talk with your doctor if this occurs.
People with Parkinson's disease may have a higher risk of skin cancer (melanoma). Talk to your doctor about this risk and what skin symptoms to watch for. You may need to have regular skin exams.
