Generic Name: pramipexole (pram i PEX ole)
Brand Name: Mirapex, Mirapex ER
What is pramipexole?
Pramipexole 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.
Pramipexole is used to treat symptoms of Parkinson's disease (stiffness, tremors, muscle spasms, and poor muscle control). Pramipexole is also used to treat restless legs syndrome (RLS).
Only immediate-release pramipexole (Mirapex) is approved to treat either Parkinson symptoms or RLS. Extended-release pramipexole (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.
Pramipexole may also be used for purposes not listed in this medication guide.
What is the most important information I should know about pramipexole?
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.
What should I discuss with my healthcare provider before taking pramipexole?
You should not use pramipexole if you are allergic to it.
To make sure pramipexole is safe for you, tell your doctor if you have:
low blood pressure;
kidney disease; or
problems controlling your muscle movements.
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.

How should I take pramipexole?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
If you are taking immediate-release pramipexole (Mirapex) you should not take extended-release pramipexole (Mirapex ER) at the same time.
The dose and timing of pramipexole in treating Parkinson's disease is different from the dose and timing in treating RLS. Follow the directions on your prescription label. Ask your pharmacist if you have any questions about the kind of pramipexole you receive at the pharmacy.
Pramipexole can be taken with or without food. Take the medication with food if it upsets your stomach.
Do not crush, chew, or break an extended-release tablet (Mirapex ER). Swallow it whole.
If you are taking this medication for RLS, tell your doctor if your symptoms get worse, if they occur in the morning or earlier than usual in the evening, or if you feel restless symptoms in your hands or arms.
Do not stop using pramipexole suddenly, or you could have unpleasant withdrawal symptoms. Follow your doctor's instructions about tapering your dose.
Store at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking pramipexole?
