Galantamine is a treatment for mild to moderate Alzheimer’s disease that works by increasing acetylcholine levels in the brain to support memory and thinking. It is available as a tablet, capsule, or liquid, giving flexibility in how it is prescribed. Galantamine may provide modest benefits in cognition, behavior, and daily activities, though it does not stop disease progression. Common side effects include nausea, vomiting, diarrhea, loss of appetite, and dizziness, especially when beginning therapy. Despite its limits, it can play a helpful role in managing Alzheimer’s symptoms and maintaining quality of life.
