Memantine comes as a tablet, a solution (liquid), and an extended-release (long-acting) capsule to take by mouth. The solution and tablet are usually taken once or twice a day with or without food. The capsule is taken once a day with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. To help you remember to take memantine, take it at around the same time(s) every day. Take memantine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release capsules whole; do not chew, divide, or crush them. If you are unable to swallow the extended-release capsules, you can carefully open a capsule and sprinkle the contents on a spoonful of applesauce. Swallow this mixture immediately without chewing it. Do not save this mixture to use at a later time.
If you are taking the oral solution, follow the manufacturer's directions to measure your dose using the oral syringe that is supplied with the medication. Slowly squirt the medication from the syringe into a corner of your mouth and swallow it. Do not mix the medication with any other liquid. After you take your medication, follow the manufacturer's directions to re-seal the bottle and clean the oral syringe. Ask your pharmacist or doctor if you have any questions about how to use this medication.
Your doctor will probably start you on a low dose of memantine and gradually increase your dose, not more than once every week.
Memantine helps to control the symptoms of Alzheimer's disease but does not cure it. Continue to take memantine even if you feel well. Do not stop taking memantine without talking to your doctor.
