Galantamine is a prescription drug used mainly for mild to moderate Alzheimer’s disease. It belongs to a class called acetylcholinesterase inhibitors, which means it helps keep a brain chemical called acetylcholine around longer. More acetylcholine can improve memory and thinking in people whose brain cells are losing function.
Doctors also sometimes prescribe galantamine for other types of dementia, but its main claim to fame is Alzheimer’s. If you or a loved one have been diagnosed with early‑stage Alzheimer’s, you’ve probably heard the name galantamine pop up during appointments.
Galantamine comes in tablets, extended‑release tablets, and oral solution. The usual starting dose for the immediate‑release tablet is 4 mg twice a day. After four weeks, the dose can be increased to 8 mg twice a day, and after another four weeks many patients move up to the full 12 mg twice a day.
Extended‑release tablets simplify the schedule: you start with 8 mg once a day, then may step up to 16 mg and finally 24 mg once daily. Your doctor will decide the best plan based on how you tolerate the medicine.
Take galantamine with food to reduce stomach upset. If you miss a dose, take it as soon as you remember—unless it’s almost time for the next dose. Don’t double up.
Most people feel fine, but some notice nausea, vomiting, loss of appetite, or diarrhea, especially when they first start. A few experience dizziness, headache, or trouble sleeping. These side effects often fade after a week or two as the body gets used to the drug.
\nIf you have a history of stomach ulcers, heart rhythm problems, or breathing issues, let your doctor know. Galantamine can interact with other medicines that affect the liver or the nervous system, such as certain antidepressants, antipsychotics, or other Alzheimer’s drugs. Always give your pharmacist a full list of what you’re taking.
Never stop galantamine abruptly; a sudden drop can worsen symptoms. If you need to stop, your doctor will taper you off slowly.
Galantamine is a prescription drug, so you need a valid prescription from a qualified prescriber. In the UK and many other countries, you can order it from registered online pharmacies that require your prescription to be uploaded.
Look for pharmacies that display their registration number (GPhC in the UK) and have clear contact information. Avoid sites that sell galantamine without asking for a prescription—those are likely illegal and could give you counterfeit medication.
Compare prices, but don’t pick the cheapest option if the pharmacy isn’t verified. Some reputable sites offer discount programs or bulk‑order savings that can lower the cost without compromising safety.
When you receive the medication, check the packaging for tamper‑evidence, correct dosage, and expiration date. If anything looks off, contact the pharmacy right away and don’t use the product.
Remember, galantamine works best when you stick to the prescribed schedule and keep regular follow‑up appointments with your doctor. Monitoring your response helps adjust the dose if needed and catches side effects early.
Overall, galantamine can be a helpful part of an Alzheimer’s treatment plan when used correctly. By understanding how it works, following dosing guidelines, watching for side effects, and buying from trusted sources, you can make the most of the medication while staying safe.
