What is galantamine?
Galantamine improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical called acetylcholine (ah see til KO leen). People with dementia usually have lower levels of this chemical, which is important for the processes of memory, thinking, and reasoning.
Galantamine is used to treat mild to moderate dementia caused by Alzheimer’s disease.
Galantamine may also be used for purposes other than those listed in this medication guide.

- seizures or epilepsy;
