Drug Interactions

Antacids, ferrous salts, bismuth subsalicylate, sucralfate and zinc salts reduce bioavailability of gatifloxacin. May increase digoxin plasma levels. Probenecid, cimetidine and loop diuretics increase gatifloxacin levels. NSAIDs may increase the risk of CNS stimulation and convulsions. Concurrent use of bepridil, cisapride, erythromycin, pentamidine, phenothiazines, or TCAs may prolong QT interval. Concurrent corticosteroid therapy may increase the risk of tendon rupture. Increased risk of hypoglycaemia when used with oral antidiabetic agents. May enhance hypoprothrombinaemic effects of oral anticoagulants. Potentially Fatal: Increased risk of adverse CV reactions when used with class IA or III antiarrhythmics e.g. disopyramide and amiodarone.

Contraindications

Hypersensitivity; children <18 yr; concurrent use of class IA or III antiarrhythmics, QT-prolongation drugs; diabetics; pregnancy, lactation.
