Galantamine is prescribed for people who have dementia which is associated with Alzheimer's disease. It is used to help the symptoms which affect thinking, such as memory loss and confusion.

Galantamine is not a cure, but it can slow down the progression of the symptoms in some people. It works mainly by increasing the level of a natural chemical called acetylcholine. This is a chemical which allows nerve cells in the brain to communicate with each other, and it is known that people with dementia have low levels of it. The symptoms of dementia can be improved by increasing the levels of acetylcholine.

Galantamine will be prescribed by a specialist doctor. If you are a caregiver, please read this leaflet on behalf of the person who is receiving galantamine.

Before taking galantamine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking galantamine it is important that your doctor knows:

  • If you have liver or kidney problems.

  • If you have problems with your heart or if you have been told you have an irregular heart rhythm.

  • If you have any problems with your breathing, such as asthma or chronic obstructive pulmonary disease (COPD).

  • If you have difficulty passing urine or have severe constipation, or if you have recently had any surgery to your stomach, intestines or bladder.

  • If you have ever had a gastric (stomach) or duodenal ulcer.

  • If you have ever had fits (convulsions).

  • If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

  • If you have ever had an allergic reaction to a medicine.

  • If you are pregnant or breastfeeding.

How to take galantamine

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about galantamine and will provide you with a full list of side-effects which you may experience from taking it.

  • Your caregiver will help you take the medicine exactly as your doctor has told you to. It is usually started at a low dose which is then increased slowly. This allows your doctor to make sure that you have the dose that helps your condition but avoids unwanted symptoms. You may find it helps to swallow your doses with a drink of water.

  • If you are taking tablets or liquid medicine, it is usual to be prescribed two doses to take each day. Ideally you should take your doses with, or soon after, your breakfast and your evening meal. Taking galantamine with food helps to prevent unwanted side-effects.

  • If you have been prescribed capsules to take, you will be prescribed one dose to take each day. This is because these are modified-release capsules, which means that they release the medicine they contain slowly over the course of the day. Modified-release capsules have the letters 'XL' after the brand name on the pack. Swallow the capsule whole without chewing or opening it. Take your dose in the morning, with or straight after your breakfast.

  • If you have been given the oral liquid medicine to take, you will be supplied with a pipette or dose syringe to measure out your doses. Each 1 ml of medicine contains 4 mg of galantamine. If you are unsure how to measure out your dose, ask your pharmacist to show you. Add your dose to any non-alcoholic drink, and drink it straightaway.

  • If you forget to take a dose at the usual time, leave out the missed dose but make sure that you remember to take your next dose when it is due. 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 to avoid becoming dehydrated.

  • Your doctor will want to check your progress every few weeks to make sure the dose is right for you and that you are getting benefit from this treatment. Try to keep these regular doctor's appointments.

  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking galantamine. This is because galantamine may affect the amount of any anaesthetic you may need.

  • If you buy any medicines, always check with a pharmacist that they are safe to take with your other medicines. Some medicines can interfere with the way galantamine works.
