Reminder! Namenda Tablets Have Been Discontinued

by The GoodRx Pharmacist on August 15, 2014 at 11:33 am

Effective Friday, August 15, 2014, Namenda (memantine) 5 mg and 10 mg tablets have been discontinued. According to the manufacturer, Forest Laboratories, the discontinuation is not for safety reasons, but because the company is going to be focusing on their once-daily Namenda XR (memantine) capsules.

What strengths and forms of Namenda XR are still available?
Namenda XR is available as a once-daily capsule in 7 mg, 14 mg, 21 mg, and 28 mg dosages.

Will Namenda oral solution still be available?

Yes. Forest Laboratories will continue to make Namenda 2 mg/ml oral solution along with the XR capsules.

How do I switch from the tablets to the XR capsules?

You can switch from Namenda tablets to an equivalent dose of Namenda XR capsules the very next day. So that your therapy isn’t interrupted, the sooner your doctor can switch you, the better.

For example:

  • If you are currently taking the Namenda 5 mg tablet twice daily your dosage would change to the Namenda XR 14 mg capsule once-daily.
  • If you are currently taking the Namenda 10 mg tablet twice daily your dosage would change to the Namenda XR 28 mg capsule once-daily.

Are there any advantages to using the Namenda XR capsules?

Yes. First, Namenda XR capsules are taken once-daily. Once-daily dosing usually means that you are more likely to use the medication.

The second advantage is that the Namenda XR capsules can be opened and sprinkled on applesauce for ease of administration. If you have difficulty swallowing pills these XR capsules would be beneficial.

The bad news?
Namenda XR will be covered by a patent for longer than Namenda—so no generic version in the near future.
