Gocovri is an antiviral medicine that blocks the actions of viruses in your body.

This medicine should not be used in place of getting a yearly flu shot. The Centers for Disease Control recommends an annual flu shot to help protect you each year from new strains of influenza virus.
Gocovri is also used to treat Parkinson's disease and "Parkinson-like" symptoms such as stiffness or tremors, shaking, and repetitive uncontrolled muscle movements that may be caused by the use of certain drugs.

How should I take Gocovri?

You may take Gocovri with or without food. You may need to take this medicine only at bedtime. Follow your doctor's instructions.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

To make swallowing easier, you may open the capsule and sprinkle the medicine into a spoonful of applesauce. Swallow the mixture right away without chewing. Do not save it for later use.

What happens if I miss a dose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of Gocovri can be fatal.
Overdose symptoms may include confusion, agitation, behavior changes, hallucinations, severe headache or pounding in your ears, muscle stiffness, problems with balance or walking, trouble breathing, fast heartbeats, or seizure.
What should I avoid while taking Gocovri?
Do not receive a nasal flu vaccine while using Gocovri, and for at least 48 hours after your last dose. The vaccine may not work as well during this time, and may not fully protect you from disease.
Do not drink alcohol. Dangerous side effects could occur.
Avoid driving or operating machinery until you know how this medicine will affect you. Gocovri may impair your thinking or reactions. Some people taking this medicine have fallen asleep during normal daytime activities such as working, talking, eating, or driving. You may fall asleep suddenly, even after feeling alert. Be careful if you drive or do anything that requires you to be alert.
Avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications) without your doctor's advice. Taking a stimulant together with Gocovri can increase your risk of unpleasant side effects.
