How can this medicine affect other medicines?

It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.

You should not take any of the following medicines at the same time of day as your levofloxacin dose, as they can reduce the absorption of the levofloxacin from the gut and make it less effective. If you need to take any of these, their doses should be separated from your levofloxacin dose by at least two hours:

antacids (for indigestion) containing aluminium or magnesium

iron preparations

sucralfate (this is best taken at least two hours AFTER the levofloxacin).

If levofloxacin is used in combination with any of the following medicines there may possibly be an increased risk of seizures (fits):

theophylline

non-steriodal anti-inflammatory drugs (NSAIDs) such as indometacin, fenbufen, naproxen.

Levofloxacin may enhance the anti-blood-clotting effect of anticoagulants such as warfarin. As this may increase the risk of bleeding, your blood clotting time (INR) should be monitored more frequently if you are taking levofloxacin in combination with an anticoagulant.

Levofloxacin may increase the blood level of the immunosuppressants ciclosporin and tacrolimus. This could increase the risk of side effects on the kidneys from these medicines.

Other medicines containing the same active ingredient

There are currently no other medicines available in the UK that contain levofloxacin as the active ingredient.
