Cautions with other medicines

There are some medicines that may affect how your HRT works because they can sometimes cause irregular bleeding.

Tell your doctor or pharmacist if you're taking any other medicines, including:

• epilepsy medicines
• some antibiotics
• medicines for tuberculosis
• medicines for HIV

Mixing sequential combined HRT with herbal remedies and supplements

There are several different herbal products sold to help relieve menopause symptoms. These include evening primrose oil, soya, red clover, black cohosh, ginseng and St John's wort.

Herbal remedies containing St John's wort may affect the way your HRT works and make it less effective.

It's not possible to say that other herbal remedies and supplements are safe to take with HRT. They're not tested in the same way as pharmacy or prescription medicines. They're generally not tested for the effect they can have on other medicines.

Any herbal product may affect other medicines you're taking, so it's important to check with your doctor or pharmacist before starting to take them.
