Namenda (memantine) : Namenda (also known as memantine) is a medication for treatment of advanced dementia. Namenda has several significant side effects. One important side effect of Namenda is insomnia and agitation, sometimes accompanied by paranoia or other signs of psychosis. This is especially likely to occur when the drug is not completely cleared from the body, a situation that could occur in individuals whose kidney function is impaired. Namenda does not have a regulatory approval for treatment of bipolar illness or depression. I am not aware of any clinical trials, case reports or any other clinical data showing that it could be of any benefit to patients with bipolar illness or depression. ...Read more

Holiday maybe: What is Adderall intolerance for you? Do you mean intolerable adverse effects? If so you should discuss other treatment options with your doctor. Namenda (memantine) is marginal at best for adhd, & is more helpful for people with learning disabilities.You may have unrecognized/untreated comorbid conditions such as depression, anxiety, ocd, or learning disabilities that are complicating treatment tolerance. ...Read more

Which alzheimer's drug is most effective: Aricept or namenda (memantine)?

Early vs later stage: Both relieve symptoms of the disease & focus on neurotransmitters key to memory and learning.

I take Namenda (memantine) 10mg once a day but have not noticed an improvement, just noticed that it has gotten worse. It has been a month, when does it kick in?

I take Namenda (memantine) 10mg once a day but have not noticed an improvement, just noticed that it has gotten worse. It has been a month, when does it kick in?

Step-by-step: The mfg suggests a weekly step up over a month from once a day 5mg thru twice a day 10mg. So, your dose is only half that. Also, it is intended for Alzheimer's not vascular - so, it might not be the best for you depending on your condition. Your doctor is the best person to discuss this all with. It's follow-up to the prescribing. Best! ...Read more

I stopped taking namenda (memantine) a few days ago because of confusion problems, how long do the effects last after stopping? I now take Donepezil 5mg

Good change, I hope: The half-life of Namenda (memantine) is no more than 80 hrs. This should mean that it will be unlikely to still have and effects in a week to 10 days. But your doctor or a pharmacist may explain it better. The new drug should not have that side effect, but watch it and discuss risks w/ the doctor too. Best wishes for good results! ...Read more
