1. what betahistine is and what it is used for

Betahistine is a type of medicine called a “histamine analogue”.

Betahistine is used for:

Meniere’s disease – the signs of this include:

  • feeling dizzy (vertigo)
  • ringing in the ears (tinnitus)
  • hearing loss or hearing difficulty

How this medicine works

This medicine works by improving blood flow in the inner ear. This lowers the build up of pressure.

2. what you need to know before you take betahistine

  • if you are allergic to betahistine or to any of the other ingredients of this medicine (listed in section 6)
  • if you have a pheochromocytoma, a rare tumour of the adrenal gland

Warnings and precautions

Talk to your doctor or pharmacist before taking Betahistine.

  • if you have or have had a stomach ulcer (peptic ulcer)
  • if you have asthma
  • if you have nettle rash, skin rash or a cold in the nose caused by an allergy, since these complaints may be exacerbated.
  • if you have low blood pressure
  • Betahistine dihydrochloride is not the appropriate treatment for the following forms of vertigo:
  • attacks of benign positional vertigo,
  • dizziness related to a disease of the central nervous system.
  • if you are pregnant or planning to become pregnant
  • if you are breast-feeding

If you suffer from any of the above conditions, consult your doctor about whether you may take Betahistine tablets.

These groups of patients should be monitored by a doctor during treatment.

Use in Children and adolescents

Betahistine is not recommended for use in children and adolescents (below 18 years of age)

Other medicines and Bethisitine

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines:

Anti-histamines – This is because in theory betahistine may not work properly. Also, betahistine may lower the effect of anti-histamines.

Monoamine-oxidase inhibitors (MAOIs) – used to treat depression or Parkinson’s di­sease. These may increase the exposure of betahistine.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Betahistine.

Taking Betahistine with food and drink

Betahistine can be taken with or without food. However, Betahistine can cause mild stomach problems (listed in section 4). Taking betahistine with food can help reduce stomach problems.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

It is not known whether betahistine dihydrochloride affects the unborn child.

Do not take betahistine dihydrochloride tablets if you are pregnant unless your doctor has decided that it is absolutely necessary. Ask your doctor for advice.

Driving and using machines

Betahistine is not likely to affect your ability to drive or use tools or machinery.
