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 kidney or mental health problems, heart failure, angle-closure glaucoma, or have ever had a seizure.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take amantadine regularly as directed with a glass of water. You can take it with or without food.

Do not stop taking amantadine suddenly without talking to your doctor first. Your doctor may reduce the dose gradually.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.
