Looking for a memantine HCl coupon? Memantine hydrochloride is the low-cost generic version of Namenda and Namenda XR, prescribed to treat moderate to severe Alzheimer's-type dementia. Because it is available as a generic, memantine is already an affordable medication, but the cash price can still vary widely from one pharmacy to the next. Rx.com compares memantine prices across more than 60,000 pharmacies so you can find the best deal in your area. Enter your ZIP code above to see today's price near you.
What is memantine and how does it work?
Memantine hydrochloride is an NMDA receptor antagonist (a type of glutamate receptor antagonist). It is FDA-approved to treat moderate to severe dementia of the Alzheimer's type. In Alzheimer's disease, excess activity of a brain chemical called glutamate is thought to damage nerve cells. Memantine works by regulating this glutamate activity, which may help with memory, attention, reasoning, language, and the ability to carry out daily activities.
It is important to understand that memantine does not cure Alzheimer's disease and does not stop the disease from getting worse over time. It is often prescribed alongside a cholinesterase inhibitor such as donepezil (the two are also available together as the combination product Namzaric). Talk with your doctor about whether memantine is right for you.
How much does memantine cost without insurance?
Because memantine is available as a generic, it is typically one of the more affordable Alzheimer's medications, and you do not need insurance to use an Rx.com discount coupon. Even so, the cash price for the exact same prescription can differ significantly between pharmacies, which is why comparing prices matters. There is no manufacturer savings card for generic memantine.
Rx.com checks memantine prices at more than 60,000 pharmacies nationwide so you can compare and pick the lowest cash price near you. Enter your ZIP code above to see today's price and print or text yourself a free coupon.
Memantine vs. Namenda and other alternatives
Memantine is the generic name for the brand-name drugs Namenda (immediate-release) and Namenda XR (extended-release). The generic contains the same active ingredient and is usually much less expensive than the brand.
Because memantine works differently from cholinesterase inhibitors, doctors sometimes prescribe it together with drugs such as donepezil, rivastigmine, or galantamine. Memantine and donepezil are also combined in a single capsule sold as Namzaric. Your doctor can help you decide which option fits your treatment plan; you can compare prices for each of these on Rx.com.
Memantine safety and side effects
Memantine does not carry an FDA boxed warning and is not a controlled substance, with a low potential for abuse. The most common side effects are dizziness, headache, confusion, and constipation. Rare but serious effects can include hallucinations, seizures, and serious allergic reactions (including a severe skin reaction called Stevens-Johnson syndrome). If you notice a rash, blistering, or trouble breathing, seek medical care right away.
Memantine is cleared from the body mainly by the kidneys, so people with severe kidney impairment may need a lower dose. Certain conditions that make the urine more alkaline, such as renal tubular acidosis or severe urinary tract infections, can also raise memantine levels in the blood. This is general information, not medical advice. Tell your doctor about your kidney health and all medicines you take, and follow their guidance.
