What Betahistine Sandoz is used for
Betahistine Sandoz is used to treat a disorder of the working of your inner ear. This disorder may include one or more of the following symptoms, in one or both ears:
- Ringing in the ears (tinnitus)
- Loss of clear hearing
- Problems with balance (vertigo)
These symptoms may also be associated with nausea, vomiting and headache. Often these symptoms together are referred to as Méniere's Syndrome.
Based on animal studies, the active ingredient of Betahistine Sandoz tablets, betahistine dihydrochloride, works by improving the blood flow of the inner ear and restoring it to normal. It also acts on the nerve endings in the inner ear to normalise the way in which the nerves respond to outside influences.
Your doctor may have prescribed Betahistine Sandoz for another reason. Ask your doctor if you have any questions about why Betahistine Sandoz has been prescribed for you.
There is no evidence that Betahistine Sandoz is addictive.
This medicine is available only with a doctor's prescription.
