Cautions with other medicines
Some medicines can affect the way that flucloxacillin works and increase the chance of you having side effects.
Check with a pharmacist or your doctor if you're taking any other medicines, including:
- methotrexate, an anti-inflammatory medicine for arthritis and similar conditions
- warfarin, a medicine to prevent blood clots
- medicines to treat gout including probenecid and sulfinpyrazone
- voriconazole, a medicine used to treat fungal infections
- other antibiotics
These are not all the medicines that may cause problems if you take them with flucloxacillin. For a full list, see the leaflet inside your medicine packet.
Important
Tell your doctor if you've recently had, or are due to have, an oral typhoid vaccination. Flucloxacillin can make it less effective.
Mixing flucloxacillin with herbal remedies or supplements
There's not enough information to say that herbal remedies and supplements are safe to take with flucloxacillin. 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.
