WHAT YOUR MEDICINE IS
1. AND WHAT IT IS USED FOR
The name of your medicine is Betahistine Dihydrochloride 8mg or 16mg Tablets. Betahistine dihydrochloride is a type of medicine called a histamine analogue. It is used as a treatment for Meniere’s syndrome, a condition caused by the pressure of excess fluid in the inner ear. Betahistine dihydrochloride is thought to work by improving blood flow in the inner ear, which reduces the build up of pressure. It is this pressure in the ear which is thought to cause the vertigo (dizziness), tinnitus (ringing in the ears) and hearing loss suffered by people with Meniere’s disease
