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.
