FAQ
Common questions about galantamine
Below you’ll find answers to a few commonly asked questions about galantamine.
What brand names are available for galantamine?
Currently, there isn’t a brand-name drug available for galantamine. Galantamine is a generic version of the brand-name drug, Razadyne. But this brand-name product is no longer available.
A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared to brand-name drugs.
You can learn more about this by talking with your doctor or pharmacist.
How does galantamine work? And how long does it take to start working?
Galantamine’s mechanism of action (how it works) is to stop the breakdown of a substance called acetylcholine (ACh). ACh helps your brain with processes involving memory and thinking. While the cause of Alzheimer’s disease isn’t clear, low levels of ACh in the brain seem to play a role in dementia. By blocking its breakdown, galantamine increases levels of ACh in the brain. This may help ease the symptoms of mild to moderate dementia. But it won’t cure Alzheimer’s disease or stop its progress.
Galantamine starts working as soon as you take it. But it can take up to 4 weeks to see its full effect on symptoms. Doctors usually wait this long before increasing the dose, if necessary.
If you’d like to know more about this, talk with your doctor or pharmacist.
Uses
Uses of galantamine

Use for dementia in people with Alzheimer’s disease
Doctors may prescribe galantamine oral tablet and extended-release oral capsule for treating mild to moderate dementia of Alzheimer’s disease. It’s used for this purpose in adults. It’s usually prescribed as a long-term treatment.
With Alzheimer’s disease, people experience a decline in their mental abilities. This is called dementia. It affects their thinking, memory, and behavior. The symptoms are usually mild in the beginning. As the disease progresses, these symptoms will start to interfere with daily living.
Galantamine can help reduce dementia symptoms. But Alzheimer’s disease is progressive, meaning it will get worse with time. Galantamine can’t stop this process, and the drug may become less effective over time.
