Across 68 first-hand reports, people mentioned a side effect 11 times (about 16 per 100 reports). The most common: vivid dreams, poor sleep, tolerance. User reports show what people notice — they can't tell you whether Galantamine is safe for you.
“Yes, unfortunately I was tired all the time. It was like getting no sleep in spite of the fact that i was in fact sleeping every night. The clarity of perceptions and beauty of lucid dreams are unparalleled by 'real life'.”
“Once in a while I also take...Galantamine. I found this improved my sleep, but you might get crazy dreams”
“I’ve had success with dream recall taking galantamine but quickly developed a tolerance.”
Conclusion: ChEIs, memantine, and GV-971 all can slow the progression of AD but have different effects on respective assessments. Donepezil and GV-971 were relatively well tolerated.
Conclusion: Here we show the significant effects of all available acetylcholinesterase inhibitors on cognitive function in patients with AD. However, further studies are needed to draw valid conclusions about the effects of acetylcholinesterase inhibitors on functional outcomes and adverse events.
Conclusion: Indirect comparisons also favored donepezil over galantamine with regard to behavior. Across trials, the incidence of adverse events was generally lowest for donepezil and highest for rivastigmine.
