Before starting tibolone, tell your GP or pharmacist if you are taking medicines:
- that help to prevent blood clots, such as warfarin
- for epilepsy, such as phenytoin or carbamazepine
- for tuberculosis, such as rifampicin
Tibolone and herbal remedies
St John's wort may stop tibolone from working as well as it should.
It's not possible to say that other herbal remedies and supplements are safe to take with tibolone.
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 GP or pharmacist before starting to take them.
