What Is Galantamine?

Galantamine is a prescription medicine given to treat memory loss and thinking problems associated with mild and moderate Alzheimer's disease.

The most important thing to keep in mind is that Galantamine is not a cure for Alzheimer's disease. However, it can help improve memory, attention, and the ability to handle everyday tasks for a period of time.

Inside our brains, nerve cells rely on chemical messengers to send signals back and forth. One key chemical is called acetylcholine, which helps support memory and thinking skills. People with Alzheimer's disease have lower levels of this chemical. Galantamine works by slowing down the breakdown of acetylcholine in the brain, helping boost its levels to ease symptoms.

Things to Tell Your Doctor Before Starting Treatment

Before your loved one starts taking Galantamine, you must share their complete health history with your doctor. Certain medical conditions can interact poorly with this medicine.

Health Condition Why Your Doctor Needs to Know
Asthma or lung problems This medicine can sometimes make breathing difficulties worse.
Heart disease or slow heartbeat Galantamine can lower your heart rate even further, making heart monitoring vital.
Kidney or liver disease Your body processes and clears medicines through these organs, so doses may need adjustment.
History of seizures or fits This treatment may slightly increase the risk of having seizures.
Stomach ulcers or gut issues The medicine can increase stomach acid production and worsen ulcers.
Trouble passing urine Galantamine can affect normal bladder control and muscle function.
Known allergies Let your doctor know if you have ever reacted badly to Galantamine or other drugs.
Pregnancy or breastfeeding Safety during pregnancy and breastfeeding has not been established.

How to Use Galantamine Properly

Galantamine comes as a liquid medicine known as an oral solution. Follow your doctor's dosing instructions very carefully.

  • Take with food: Take the medicine during a meal or right after eating with a full glass of water to help prevent stomach upset.
  • Stick to a schedule: Take your prescribed dose at the exact same times every day and never skip doses.
  • Do not stop suddenly: Even if your loved one feels better, do not stop giving this medicine without talking to your doctor first.
  • Missed doses: Take the missed dose as soon as you remember. If it is almost time for the next scheduled dose, skip the missed one and stay on your normal schedule. Never take two doses at the same time. If you miss taking doses for more than three days, contact your doctor before starting again.
