Antifungal medicines - Interactions 

Interactions with other medicines 

When two or more medicines are taken at the same time, the effects of one of the medicines can be altered by the other. This is known as a drug-drug interaction. Some antifungal medicines can interact with other medicines.

Tell your GP or pharmacist what other medicines you are taking, including over-the-counter medicines, so they can decide whether an antifungal medicine is safe for you to take.

  • oestrogens – hormones found in some contraceptives
