Memantine may not be covered through Medicare Part D
Memantine, a medication for the treatment of Alzheimer’s symptoms that recently became available as a generic drug, may not be covered through Medicare Part D. As open enrollment for Medicare Part D ends on Dec. 7, 2015, now is the time to explore your coverage. If you or someone you know is taking memantine, check with your plan, or contact your State Health Insurance Program (SHIP) through Medicare and ask to speak to a counselor. You may also want to consult with your physician about medication options.
