1. Why am I using Betahistine Lupin?

Betahistine Lupin contains the active ingredient betahistine dihydrochloride.

Betahistine Lupin 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.

Betahistine Lupin tablets contain the active ingredient betahistine dihydrochloride, which work 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 normalize the way in which the nerves respond to outside influences.

Your doctor may have prescribed Betahistine Lupin for another reason. Ask your doctor if you have any questions about why Betahistine Lupin has been prescribed for you.

There is no evidence that Betahistine Lupin is addictive.
