The daily dose of Prograf should be divided in two intakes separated by twelve hours. The capsules should be taken immediately after taking them out from the blister packs with full glass of water on an empty stomach, or at least one hour before or 2-3 hours after a meal.

Drug interaction

Prograf may slow down metabolism of Cyclosporine (Neoral, Sandimmune, Gengraf) thus increasing its toxicity. As Prograf is metabolized by cytochrome CYP 3A4, a concomitant use of medications affecting or being metabolized by this cytochrome may change Prograf levels in the blood (for example testosterone, cortisone). Tacrolimus binds to proteins of blood serum and and may change (mutually) effects of the medications with high affinity to serum proteins such as peroral anticoagulants, diabetic drugs or NSAIDs. Concomitant use of Prograf with neurotoxic or nephrotoxic medication may increase toxicity (aminoglycosides, inhibitors of DNA gyrase, vancomycin, co-trimoxazole, NSAIDs, ganciclovir or acyclovir). Avoid co-administration of Prograf with potassium-saving diuretics of medicines which contain potassium to avoid hyperpotassemia (Dyazide, Maxzide, amiloride, Moduretic, and spironolactone, Aldactone). Effects of vaccination may be decreased and use of live attenuated vaccines should be avoided. Inform your doctor about all drugs and herbal products you are taking.
