What is Mirapex ER?

See also: Gocovri

Mirapex ER has some of the same effects as a chemical called dopamine, which occurs naturally in your body. Low levels of dopamine in the brain are associated with Parkinson's disease.

Mirapex ER is used to treat symptoms of Parkinson's disease (stiffness, tremors, muscle spasms, and poor muscle control). This medicine is also used to treat restless legs syndrome (RLS).

Only immediate-release Mirapex ER (Mirapex) is approved to treat either Parkinson symptoms or RLS. Extended-release this medicine (Mirapex ER) is approved only to treat Parkinson symptoms.

Parkinson's and RLS are two separate disorders. Having one of these conditions will not cause you to have the other condition.

Mirapex ER may also be used for purposes not listed in this medication guide.

Important Information

Tell your doctor if you have ever had:

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.
