Namenda XR, also known as memantine hydrochloride, is indicated for the treatment of moderate to severe dementia associated with Alzheimer's disease.

It functions as an N-methyl-D-aspartate (NMDA) receptor antagonist, which means it works by reducing the actions of certain chemicals in the brain that may contribute to the symptoms of Alzheimer's disease.


  • Before starting Namenda XR, read the Patient Information Leaflet provided by your pharmacist. This leaflet contains important information about the medication and its usage.
  • Namenda XR should be taken by mouth with or without food, as directed by your healthcare provider. It is usually taken once daily.
  • The capsules should be swallowed whole and should not be crushed or chewed. Crushing or chewing the capsules can release all of the drugs at once, increasing the risk of side effects.
  • If you have trouble swallowing the capsules whole, you may open the capsule and sprinkle the contents on applesauce. Swallow the entire mixture without chewing. 
  • The dosage of Namenda XR is based on your medical condition and response to treatment. Your healthcare provider may start you on a low dose and gradually increase it to reduce the risk of side effects. Follow their instructions carefully.
  • If you are switching from another form of memantine to the extended-release form (Namenda XR), follow your healthcare provider's instructions.
  • To ensure the most benefit from Namenda XR, take it at the same time each day.
  • If your condition worsens while taking Namenda XR, inform your healthcare provider.


  • Do not prepare a supply in advance.
  • Do not switch forms without consulting your healthcare provider first.
