Reviews for Memantine

Leggy · Taken for 6 months to 1 year January 29, 2021

For Alzheimer's Disease: “My wife who has Vascular Dementia/ Alzheimer's Disease . She has tried this drug twice. First time she started on a low dose memantine and built up to 20mg. Her condition became worse over a period of time. I was not sure if this was a normal progression of her condition. We stopped the drugs and within two weeks she had settled down and things were more manageable. A year later we have tried the drug again on a low dose 5mg . The confusion became worse. So we have stopped them again. It is hard to know if there are any benefits from this drug in our experience.”

Namenda (memantine) for Alzheimer's Disease: “Mother-in-law has Alzheimer’s and it was severe to where she went into a memory care. Once she started Namenda within second week it was like she was back to her old self. She was able to get up her her self dressed like she had did prior to the alzheimers. It was truly unbelievable. This medicine has given us more time with our loved one. She was active psychosis delusional, hallucinating 24/7. Unbelievable. I can not say enough good things about this medication. She was tired the first week but that was good rather to rest than to be awake delusional. Thinking she is ready for a increase where she is getting her nighttime/early morning bad dreams back again. But it has been 2 years since she started this medication. Please everyone please give this medication time to work. It is a miracle medicine. Give it at least 2 weeks same time daily. I read reviews and it can be a mess just after a few days. The med is fully working yet please give it another chance and more time. amazing”

Namenda (memantine) for Alzheimer's Disease: “My mother has been taking Namenda for Alzheimer's for over a year now. She was first prescribed Aricept which made her more anxious/hyperactive & no noticeable positive impact. After 2 weeks of Namenda, there was noticeable improvement in her cognitive abilities. In fact, the light bulb finally went off & she realized she had Alzheimer's. She spent the next several days on the phone breaking the news to family and friends, who had known for over 2 years by that time. My opinion: Namenda keeps her in 2013 - in the present. Her logic, reasoning, problem-solving skills, short term memory, comprehension and communication skills are impaired from the disease, but she recognizes this and acknowledges her feelings of confusion.”

Namenda (memantine) for Alzheimer's Disease: “It was a wonderful drug for my mother, with dementia, at 77. They first prescribed Aricept, which caused nausea. Asking the doctor 'what other drug may work'? She recommended Nameda. It became a miracle. It did not rectify some of the mental losses, but she no longer experienced hallucinations (in jail; on a boat). It came at the end of the year when insurance wouldn't pay for the drug. So I waited for two weeks without drug to resume insurance at the first of the year. During this time she regressed mentally. As soon as I started it again, she improved-true testament. I was able to have my mom back for two years until stroke. I swear by Namenda for only my mother. I tell everyone. As with any drug, it may not work for others, but it was truly a God-send for my sweet mother. She and I were lucky.”

Namenda (memantine) for Alzheimer's Disease: “We started my Dad on Namenda and by day 2 he was more confused, lost and irritable than usual so my Mom stopped it. The Dr asked her to start again and the same day he experienced the same side effects so she stopped. Last week she decided to try it one more time to make sure. Dad was VERY confused and not easy to take care of. I guess he is just one of those people that can't take this medication. Too bad. It helps so many people.”

Namenda (memantine) for Alzheimer's Disease: “My father has significantly improved since taking Namenda and Aricept combined, as well as 24 caregiver support at home. We believe that the combination has helped dad's cognitive function not just by medication alone, but because he had companionship 24 hours a day. Dad was confused, always thought he was at work and wanted to go home. He forgot who we were and even made sexual moves towards people he would not have otherwise have when he did not have Alzheimers. The symptoms or behaviors he still has is occasional memory loss but very little, he is still paranoid and thinks people are stealing from him or going in his property when they are not, and he occasionally still sees people or animals that aren't there. But the confusion of who we were, where he was and the wandering and wanting to "go home" even when he was home is no longer an issue. My dad is only 73 and he was diagnosed last year with Alzheimer's.”

Namenda (memantine) for Alzheimer's Disease: “Horrible drug! No help at all and they wanted my dad to take more! He just passed away from surgery complications but after being off it he was NORMAL. The doctor had him on so many meds, this being one along with Zoloft. These mind altering drugs are BAD! Also avoid Haldol. If you have a loved one PLEASE get them off these, I don't buy into these did wonders for my mom or dad, probably written by the drug companies reps. Watch the World News EVERY OTHER AD is a drug ad. The less you take the better. I'm sorry we gave these to my dad.”

Namenda (memantine) for Alzheimer's Disease: “My sister has Moderate Frontal Lone Alzheimer’s. She was extremely agitated, angry and weepy. She was withdrawing into herself and had little awareness of her surroundings and had difficulty with dressing and toileting. Literally after the first day of Namenda 20mg it was like someone turned the lights on. It’s been 2 months now and she is aware and able to go for walks by herself; dress herself and play the piano. Her memory and executive function continue to be poor. Nothing short of a miracle. Not sure how long this will last.”

Namenda (memantine) for Alzheimer's Disease: “My PCP put me on Namenda to supplement my Aricept for Alzheimer's Disease . Seems to help my short term memory. However my memory lapses happen every 2 weeks or so and only for a short period. When it is working I can think clearly. I'm 62 and thankful for this medication.”

Namenda (memantine) for Alzheimer's Disease: “My mother has taken Namenda twice now. The first time she was so confuse after a week I stopped giving it to her. She has gotten worse over the years and for some reason her doctor had given me a new prescription for the same medicine. I tried it for two days and saw my mother become extremely confused so I stop giving it to her. I don't know why he insisted on Namenda after I told him it didn't work the first time.”

For Autism: “A life saver. I have autism. It is pretty bad autism. I saw help on day one. But it isn't a fix-it-all for me. Being able to understand nonverbal communication and verbal communication is huge improvements. This help me with social interaction. This help me with anxiety. Helps my expressive myself and respond better. Less meltdowns. Helps my cognitive functions Helps me think Helps my thought issue due to my autism and auditory processing disorder Helps me slow down my mind to pay attention more and can respond to changes and sensory problems. Not a full fix for me but huge help. I am more polite. I can talk about others interest not just my needs or wants or questions that I had trouble asking. Better behavior.”

Namenda (memantine) for Alzheimer's Disease: “My wife (74) has been taking Namenda since the first diagnosis of Alzheimers two years ago. She also takes any supplement that promises to help retain or improve memory. Her memory has stayed about the same or gotten a little worse in that time. She has also taken Aricept during the same period.”

For Alzheimer's Disease: “I haven't experienced this firsthand but I've been researching this drug thoroughly, and I am conflicted with it's efficiency. Of course, it will be a different reaction for everyone; not everyone is the same. And I don't know which is harder; treating for it and getting side effects, or not, and losing your memory. My heart goes out to every person who has to go through that, and their families as well.”

Namenda (memantine) for Alzheimer's Disease: “My mom has been on this medication for one year and her condition (Dementia) is getting worst. She's hallucinating, aggressive, and extremely confused. It's seems as if this medication is making things worst and speeding up the progress of the dementia. This drug should not be on the market. I will bring her to her Psychologist soon and I will be asking for this drug to be taken off her daily medication intake. Please say no to this drug.”

She is now 15, Magna Cum Lauda with goals of becoming a forensic pathologist. She is involved in choir, student counsel and has a number of friends. It has made an overwhelming difference in the quality of her life and her ability to better control her compulsive behaviors”

For Alzheimer's Disease: “Problem. Patient forgets recent events and the doctor told us it was due to insufficient blood supply to the brain. And prescribed Dement (memantine). Immediately (2 days) condition worsens to hallucinations and confusion. Took some two other vitamins from a pharmacist for 3 months. Patient was clearly getting better in fact even the recent memory was getting better, with the vitamins. Went back to the neurological doctor and explained every thing to him. He told us to reuse memantine and by the third day the negative side effects we were back. As of tomorrow it will be taken off”

For Autism: “I was first prescribed this for Asperger's syndrome at the age of 24. I've been on numerous types of medications since I was a teenager, but this is the first one that I've been on that has significantly helped. My quality of life is much better, I don't have as many ruminating, obsessive thoughts that make me miserable.”

Namenda XR (memantine) for Alzheimer's Disease: “My wife began the 4 stage process a couple of months ago, and I stopped it halfway through week 2 because she seemed to be getting more confused. We started again a month ago and are into the 2nd full dose, and I am very concerned that her condition is worse instead of better.”

Namenda XR (memantine) for Alzheimer's Disease: “My wife tried to add Namenda as a component of combination therapy but after continuous bouts of bronchitis we terminated Namenda and, as a result, she was (in short order) able to get rid of the bronchitis. Since Namenda had seemed promising (initially, before bronchitis), we were very disappointed that it seemed necessary to eliminate that component of her treatment. Although our neurologist had not previously seen a case in which bronchitis was a side effect of Namenda, he suggested we try Namenda XR. We are thrilled that she has been able to take Namenda XR without experiencing such a side effect and that Namenda XR appears to be providing desired benefits.”

For Autism: “I take 10mg twice daily for autism spectrum disorder. It stops the intrusive thoughts, rumination, and repetitive thinking which is a Godsend. It also reduces repetitive behaviour/stereotypes. I haven't noticed any side effects, maybe a little brain fog, but that has disappeared with continued use.”

For Alzheimer's Disease: “Both of my parents suffer (ed) from Alzheimer's. My mother died last summer, 8 years after her diagnosis and never took any medication except for Lorazapam. My Dad was diagnosed with Alzheimer's 6 months ago He began taking Ariecpt in November and Mamantadine in December. In five moths he has degenerated so rapidly that he is functioning at the same level as my mom was at in her last year of the disease. Every time the dose is increased he gets exponentially worse its noticeable almost daily. I am in the process of titration him off both. I wish I would have research it better. I thought that was the doctors job. This is the first online review I have written. Grateful to hear that I'm not imagining these side effects. Thanks”
