What is betahistine?
Betahistine is thought to work by improving blood flow to your brain and affecting nerve cells in your inner ear. It is used to treat symptoms such as dizziness, vertigo, loss of balance, ringing in your ears (tinnitus) and hearing loss associated with Meniere's disease.
It is unlikely to stop all these symptoms, but it may reduce how often these occur and their severity. Your doctor may advise you to try betahistine for 6 to 12 months to see if it helps to reduce your symptoms. If it does, it can then be continued.
- The usual dose of betahistine is half a tablet (8 milligrams) or one tablet (16 milligrams) taken 3 times daily. However, depending on your response. your doctor may tell you to take different doses.
- Always take your betahistine exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much betahistine to take, how often to take it and any special instructions.
How to take betahistine
- Take your betahistine tablets with a glass of water.
- Take betahistine at the same times each day.
- It is best taken with or after food, to prevent stomach upset.
- Limit or avoid drinking alcohol while you are taking betahistine.
- Keep taking betahistine every day. It usually takes 1 to 2 weeks before any response to betahistine is noticeable.
