1. WHAT BETAHISTINE TABLETS ARE AND WHAT THEY ARE USED FOR
Betahistine Tablets contain 8 mg or 16 mg of the active ingredient betahistine dihydrochloride. Betahistine Tablets belong to a group of medicines known as histamine analogues, which means it closely resembles histamine - a chemical found naturally in the body.
Betahistine works by improving blood flow in the inner ear, which reduces the build up of pressure. It is this pressure in the ear that causes vertigo (dizziness), tinnitus (ringing in the ears), and hearing loss suffered by people with Meniere's disease.
2. BEFORE YOU TAKE BETAHISTINE TABLETS Do not take Betahistine Tablets if you
• are allergic (hypersensitive) to betahistine or any of the other ingredients of Betahistine Tablets (see list of ingredients in Section 6). An allergic reaction may include rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue
• have a phaeochromocytoma (a very rare tumour of the adrenal gland)
Take special care with Betahistine Tablets if you have
• had a peptic ulcer. Your doctor will monitor you closely during your treatment.
• asthma. Your doctor will monitor you closely during your treatment.
Taking other medicines
Please tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines, including medicines obtained without a prescription.
In particular, tell your doctor or pharmacist if you are taking any of the following medicines:
• Anti-histamines - these may (in theory) lower the effect of Betahistine Tablets. Also, Betahistine Tablets may lower the effect of anti-histamines.
• Monoamine-oxidase inhibitors (MAOIs) - used to treat depression or Parkinson’s disease. These may increase the blood level of Betahistine Tablets.
Pregnancy and breast-feeding
Do not take Betahistine Tablets if you are pregnant unless your doctor has decided that it is absolutely necessary for your treatment.
Do not breast-feed while using Betahistine tablets unless instructed by your doctor. It is not known if betahistine passes into breast milk.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Betahistine Tablets are not likely to affect your ability to drive or operate machinery, although the vertigo, tinnitus and hearing loss associated with Meniere’s syndrome (for which you are taking betahistine) can make you feel dizzy or be sick, and may affect your ability to drive or use machines. Make sure you know how this medicine affects you before you drive or operate machines.
Important information about some of the ingredients of Betahistine Tablets
Betahistine Tablets contain lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

Always take any tablets left over with you and also the box, as this will allow easier identification of the medicine.
