Taking anastrozole with other medicines and herbal supplements

There are very few medicines that affect the way anastrozole works in the body.

However, do not take hormone replacement therapy (HRT) or any other medicines that relieve menopause symptoms. These may contain ingredients similar to the hormone oestrogen and could stop anastrozole working as well as it should.

Do not take any herbal remedies or supplements for menopause symptoms while taking anastrozole. These may stop anastrozole working as well as it should.

There's not enough information to say that other complementary medicines, herbal remedies and supplements are safe to take with anastrozole. 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 remedies, vitamins or supplements.
