What is Galantamine used for?
- Mild-to-moderate Alzheimer's disease (AD)
How Galantamine works
It's not known exactly what causes Alzheimer's disease. But, researchers suggest that people with Alzheimer's might have less acetylcholine activity in the brain. Acetylcholine is a chemical in the body that's important for sending signals through nerves related to memory and learning.
Galantamine is an acetylcholinesterase inhibitor. Though unclear how the medication exactly helps with Alzheimer's, it's thought to prevent the breakdown of acetylcholine.

Pharmacist tips for Galantamine
- Make sure you take galantamine with a full glass of water and stay hydrated throughout the day. This medication can make you dehydrated.
- Galantamine commonly causes stomach side effects, like nausea, vomiting, and stomach upset. Take each dose with a meal to help.
- Take galantamine exactly how your provider tells you to. Don't raise your dose on your own. Taking higher doses too quickly can lead to unwanted side effects.
- Let your provider know if you miss more than three days of galantamine in a row. You might need to restart the medication at a lower dose.
- Be sure to let your provider know if you have any planned procedures or surgeries that will require anesthesia. Galantamine can affect how well the medications used for anesthesia work.
Additional tips for the oral solution:
- Make sure to use the measuring device that comes with the solution to measure out your galantamine dose. Don't use kitchen spoons because this could cause you to take the wrong dose.
- After you've measured your dose, add it to a cup with 100 mL of a non-alcoholic liquid (e.g., water, juice). Stir well. Then, drink the mixture right away.
- Rinse the syringe after each use by inserting it in a glass of water and pulling and pushing the plunger.
- Store the galantamine solution at room temperature. Don't freeze it because this could damage the medication.

Nonsteroidal anti-inflammatory drugs (NSAIDs), which are commonly found in over-the-counter cold and pain medications, can also raise your risk of stomach bleeds. You might want to avoid taking these medications at the same time as galantamine. Talk to your provider if you have worsening upset stomach, heartburn, or indigestion.
