Taking betahistine with other medicines and herbal supplements

Some medicines and betahistine affect each other and can increase your chance of side effects.

Tell your pharmacist or doctor if you're taking:

• medicines called MAO inhibitors, used to treat depression or Parkinson's disease
• antihistamines for allergies such as hay fever

There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to take with betahistine. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.

Tell your doctor or pharmacist if you're taking any other medicines, including herbal medicines, vitamins or supplements.
