About betahistine

Maladie de Ménière is a condition of the inner ear. It typically causes attacks of dizziness with a spinning sensation (vertigo), hearing loss and noises in the ear (tinnitus). The attacks can vary in severity, and in how often they occur. It is thought that a build-up of fluid in the inner ear causes the symptoms. Treatment can help to ease and prevent symptoms.

Betahistine is thought to work by increasing the blood flow around the inner ear. This reduces the amount of fluid in the inner ear and prevents symptoms from developing.

Before taking betahistine

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 betahistine it is important that your doctor knows:

• Si vous êtes enceinte ou si vous allaitez.

• Si vous avez déjà eu un ulcère à l'estomac.

• Si vous avez de l'asthme.

• If you have a tumour on your adrenal gland, called phaeochromocytoma.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.

• Si vous avez déjà eu une réaction allergique à un médicament.

How to take betahistine

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

• Take betahistine exactly as your doctor tells you to. It is usual to take one 16 mg tablet three times a day at first. Once your symptoms are under control, your doctor may then reduce your dose to one 8 mg tablet three times a day. You will find the directions for taking the tablets on the label of the pack to remind you about what the doctor said to you. Where possible, take betahistine tablets with something to eat, such as a snack or straight after a meal.

• Swallow the tablet with a drink of water. Try to take your doses at the same times of day each day, as this will help you to remember to take the tablets regularly.

• If you forget to take a dose, do not worry, just remember to take the next dose when it is due. Do not take two doses together to make up for a forgotten dose.

Tirer le meilleur parti de votre traitement

• If you are a driver, you must stop driving when Ménière's disease is diagnosed. This is because you may have sudden attacks of a spinning sensation (vertigo) with little warning. The Driver and Vehicle Licensing Agency (DVLA) will allow driving again when your symptoms are well controlled. Taking betahistine will not affect your ability to drive.

• If you take betahistine every day it is unlikely to stop all attacks, but it may reduce the number and/or the severity of your attacks. Your doctor may advise a trial of betahistine for 6-12 months to see if it helps to reduce your symptoms. If it does, it can then be continued.

• Some people with Ménière's disease claim their symptoms improve with a low-salt diet, regular exercise, stopping smoking, and cutting out caffeine and alcohol. Although there is little evidence to prove that diet and lifestyle can help, these may be worth trying.

• If you buy any medicines, check with a pharmacist that they are suitable to take with betahistine. Betahistine may not be as effective if it is taken alongside a medicine containing an antihistamine.

Can betahistine cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.

The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
