Cautions with other medicines
There are some medicines that do not mix well with erythromycin. Tell your doctor if you're taking any of these medicines before you start erythromycin:
- antihistamine medicines, such as astemizole, terfenadine or mizolastine
- domperidone, an anti-sickness medicine
- medicines for mental health problems called pimozide or amisulpride
- migraine medicines called ergotamine or dihydroergotamine
- simvastatin, a cholesterol-lowering medicine
- tolterodine, a bladder weakness medicine
- anticoagulants like warfarin or rivaroxaban, which help to prevent blood clots – erythromycin can increase the risk of bleeding
Mixing erythromycin with herbal remedies and supplements
There's not enough information to say that complementary medicines and herbal remedies are safe to take with erythromycin. 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.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
