About memantine

Memantine 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. You can find out more about medicines like memantine in the separate leaflet called Medicines for dementia.

Memantine is not a cure, but it can slow down the progression of the symptoms in some people. It works by reducing the amount of a brain chemical called glutamate. It is thought that this may help to slow down the damage to brain cells affected by Alzheimer's disease.

Memantine will be prescribed by a specialist doctor. It is prescribed for people with moderate or severe Alzheimer's disease, who for some reason cannot take the other medicines more usually prescribed for Alzheimer's disease. It will only be started for people who have a caregiver able to supervise the treatment. If you are the caregiver, please read this document on behalf of the person who is receiving memantine.

Before taking memantine

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

• אם יש לך בעיות בתפקוד הכליות שלך, או בעיות בתפקוד הכבד שלך.

• If you have ever had fits.

• אם אתה נוטל או משתמש בתרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• אם אי פעם הייתה לך תגובה אלרגית לתרופה.

How to take memantine

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

• Your caregiver will help you take your tablets/medicine exactly as your doctor tells you to. Take one dose every day.

• Your doctor will start you on a dose of 5 mg and then gradually increase your dose over the following few weeks. This allows your doctor to make sure that you have the dose that helps your condition but avoids any unwanted symptoms.

• You can take memantine at whatever time of day you find easiest to remember, but try to take your doses at the same time of day each day. It can be taken either with or without food.

• Doses of the oral liquid medicine must be measured using the dose pump which is supplied with the bottle. When you first open a bottle, attach the pump to the bottle and 'prime' it by pushing the head of the pump down five times. Throw away any solution that comes out of the bottle as you do this. The next time you use the pump, it will provide a dose of 5 mg every time you push it down fully. Measure out the correct dose on to a spoon or into a glass of water. If you are at all unsure of what to do or how to use the pump to measure out the correct dose, ask your pharmacist to show you.

• If you have been given soluble tablets, dissolve the tablet in half a glass of water and drink it straightaway. Alternatively, soluble tablets can be swallowed whole with a drink of water.

• If you have been given melt-in-the-mouth (orodispersible tablets), place the tablet on your tongue and allow it to dissolve before swallowing. Handle the tablets as little as possible and do not touch them with wet hands as they will start to dissolve.

• If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• It may take several weeks before memantine appears to take effect. Continue to take your doses every day until you are told otherwise by your doctor.

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

• There are several strengths of memantine tablet available - 5 mg, 10 mg, 15 mg, and 20 mg. Each time you collect a fresh supply, check the label on the box to make sure it is the strength of tablet you are expecting.

• If you make any major changes to your diet, please let your doctor know. This is because your dose may need adjusting if, for example, you change from a diet that includes meat, to one that contains only vegetables.

• If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking memantine. This is particularly important if you are going to need a general anaesthetic.
