What does it do?

Amantadine is used to treat Parkinson’s disease and sometimes other conditions.

Before you start

• Tell your doctor if you have heart, blood pressure, kidney, stomach, bowel or mental health problems (such as depression).
• Tell your doctor if you have trouble peeing, glaucoma, tardive dyskinesia, eczema, or have ever had a seizure.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Other information:

• Amantadine can impair your ability to do tasks such as driving or using machines. Alcohol makes this worse. Discuss your risk with your health professional. (search NZTA - Are you safe to drive?)
• Do not stop taking amantadine suddenly without talking to your doctor first. Your doctor may reduce the dose gradually.
