Brand Name: Razadyne
Galantamine is used for:
Treating mild to moderate dementia (eg, impairment of memory or judgment, abstract thinking, changes in personality) in patients with Alzheimer disease.
Galantamine is a cholinesterase inhibitor. It works by increasing the amount of a certain substance (acetylcholine) in the brain, which may help reduce symptoms of dementia in patients with Alzheimer disease.
Do NOT use galantamine if:
- you are allergic to any ingredient in galantamine

Contact your doctor or health care provider right away if any of these apply to you.
