Pramipexole is used alone or with other medications to treat Parkinson's disease. It can improve your ability to move and decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. It may also decrease the number of episodes of not being able to move ("on-off syndrome").

This medication is also used to treat a certain medical condition (restless legs syndrome - RLS) that causes an unusual urge to move the legs. Symptoms usually occur at night along with uncomfortable/unpleasant feelings in the legs. This medication can decrease these symptoms and thereby improve sleep.

Pramipexole is a dopamine agonist that works by helping to restore the balance of a certain natural substance (dopamine) in the brain.

Some people taking pramipexole have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with pramipexole even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
