|Type of medicine||Acetylcholinesterase inhibitor|
|Used for||Mild to moderate dementia associated with Alzheimer's disease|
|Available as||Tablets, modified release capsules, and oral solution|
Galantamine cannot cure dementia or Alzheimer's disease but it can slow down the progression of dementia and can help to ease the symptoms of memory loss, confusion and changes in behaviour. It works by increasing the amount of a natural chemical in the brain called acetylcholine which is known to be lower in people with Alzheimer's dementia.
Before taking galantamine
Before taking galantamine make sure your doctor or pharmacist knows:
- If you have liver, kidney or heart problems.
- If you have ever had a stomach ulcer.
- If you have asthma or any other problem which affects your breathing.
- If you have difficulty passing urine or have severe constipation.
- If you have recently had any surgery to your stomach, intestines or bladder.
- If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
- If you have ever had an allergic reaction to this or any other medicine.
- If you are pregnant or breast-feeding.
How to take galantamine
- Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
- Take galantamine exactly as your doctor has told you. It is usually started at a low dose and then increased slowly. This is to reduce the risk of unpleasant side-effects.
- Take galantamine with a snack or just after a meal.
- If you are taking the modified release form of galantamine (Reminyl® XL), swallow the capsules whole. Do not chew or open the capsules.
- Try to take your doses of galantamine at the same times each day to avoid missing any doses.
- Doses of the oral solution are measured using a pipette which is supplied with the bottle. Each 1 ml contains 4 mg of galantamine. If you are unsure how to measure out your dose, ask your pharmacist to show you. The solution can be taken mixed with any non-alcoholic drink.
- If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Make sure that you drink plenty of water while you are taking galantamine.
- Keep your regular appointments with your doctor so your progress can be monitored. Your doctor may want to increase your dose as you adjust to the new medicine.
- It may take several weeks before galantamine appears to take effect.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking galantamine.
- If you buy any medicines, check with a pharmacist that they are safe to take with your other medicines.
