Consumer Medicine Information
What is in this leaflet
This leaflet answers some of the common questions people ask about Betahistine GH. It does not contain all the information that is known about Betahistine GH. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking Betahistine GH against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What Betahistine GH is used for
Betahistine GH is used to treat a disorder of your inner ear. This disorder may include one or more of the following symptoms in one or both ears:
- ringing in your 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 Meniere’s Syndrome.
Betahistine GH tablets contain the active ingredient betahistine dihydrochloride. Betahistine 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 will have explained why you are being treated with Betahistine GH and told you what dose to take.
Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
This medicine is only available with a doctor’s prescription. Your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.
Betahistine GH is not addictive.
