Uses

USES: Memantine is used to treat moderate to severe confusion (dementia) related to Alzheimer's disease. It does not cure Alzheimer's disease, but it may improve memory, awareness, and the ability to perform daily functions. This medication works by blocking the action of a certain natural substance in the brain (glutamate) that is believed to be linked to symptoms of Alzheimer's disease.

How to use MEMANTINE EXTENDED-RELEASE - ORAL

HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking memantine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food as directed by your doctor, usually once daily. Swallow the capsules whole. Do not crush or chew the capsules. Doing so can release all of the drug at once, increasing the risk of side effects. If you have trouble swallowing the capsules whole, the capsule may be opened and the contents may be sprinkled on applesauce. Swallow all of the drug/food mixture right away without chewing. Do not prepare a supply in advance. The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. If switching from another form of memantine to the extended-release form, follow your doctor's instructions carefully. Do not switch forms of memantine without talking to your doctor first. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Tell your doctor if your condition worsens.
