Taking flucloxacillin with other medicines and herbal supplements

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.

Tell your doctor if you've recently had, or are due to have, an oral typhoid vaccination. Flucloxacillin can make it less effective.
