What is memantine HCl ER and how does it work?
Memantine is an NMDA-receptor antagonist indicated for moderate to severe dementia of the Alzheimer's type. The extended-release capsule is taken once daily and works by moderating the activity of glutamate, a brain chemical that can overstimulate nerve cells when present in excess in Alzheimer's disease; the goal is to help slow the decline in day-to-day functioning, not to reverse or cure the disease.
The brand-name Namenda XR is no longer marketed in the US; memantine HCl extended-release capsules are available only as a generic from multiple manufacturers today.
Comparing generic pricing
Because Namenda XR is no longer sold as a brand, essentially everyone filling this prescription today is getting the generic. Even so, cash prices for the same generic capsule can differ a fair amount between pharmacies. Rx.com compares pricing across 60,000+ pharmacies so you can find the lower-cost option near you, which matters for a medication many patients take long-term.
- Ask your pharmacy about 90-day fills, which can lower the per-dose cost for a maintenance medication like this
- Compare cash pricing even with insurance, since some plans' copays are higher than the cash price
Alternatives and related dementia medications
Memantine is sometimes combined with a cholinesterase inhibitor such as donepezil for Alzheimer's disease, and immediate-release memantine tablets are another dosing option some doctors prefer. Any change to an Alzheimer's medication regimen should be made with the prescribing doctor, since abrupt changes can affect symptom control.
Safety information
The most common side effects reported with memantine HCl ER include headache, dizziness, and diarrhea. Patients with severe kidney impairment typically need a lower target dose, so tell your doctor about any kidney problems. As with any medication for a person with cognitive impairment, caregivers should watch for new or worsening confusion, and contact the prescribing doctor with questions about dosing changes.
