IMPORTANT DRUG INTERACTIONS

Potentially hazardous interactions with other drugsAntibacterials: metabolism accelerated by rifampicin; metabolism possibly inhibited by erythromycinAnticoagulants: efficacy of coumarins may be alteredAnti-epileptics: metabolism accelerated by carbamazepine, barbiturates, phenytoin and primidoneAntifungals: increased risk of hypokalaemia with amphotericin – avoid concomitant use; metabolism possibly inhibited by itraconazole and ketoconazole. Antivirals: concentration possibly increased by ritonavirCiclosporin: rare reports of convulsions in patients on ciclosporin and high-dose corticosteroids; increased half-life of deflazacortCytotoxics: increased risk of haematological toxicity with methotrexateDiuretics: enhanced hypokalaemic effects of acetazolamide, loop diuretics and thiazide diureticsVaccines: high dose corticosteroids can impair immune response to vaccines; avoid concomitant use with live vaccines
