Drug-Drug interaction

Risk of nephrotoxicity is ↑ by concurrent use of aminoglycosides, amphotericin B, cisplatin, or cyclosporine (allow 24 hr to pass after stopping cyclosporine before starting tacrolimus).Concurrent use of potassium-sparing diuretics, ACE inhibitors, or angiotensin II receptor antagonists ↑ risk of hyperkalemia.The following drugs ↑ tacrolimus blood levels: azoleantifungals, bromocriptine, calcium channel blockers, chloramphenicol, cimetidine, clarithromycin, cyclosporine, danazol, erythromycin, lansoprazole, magnesium/aluminum hydroxidemethylprednisolone, omeprazole, nefazodone, metoclopramide, protease inhibitors, and voriconazole.Phenobarbital, phenytoin, caspofungin, sirolimuscarbamazepine, and rifamycins may ↓ tacrolimus blood levels.Vaccinations may be less effective if given concurrently with tacrolimus (avoid use of live-virus vaccines).Concomitant use with astragalus, echinacea, and melatonin may interfere with immunosuppression.St. John's wort may ↓ tacrolimus blood levels.

Route/Dosage

Topical (Adults) Apply 0.03% or 0.1% ointment twice daily. Discontinue when signs/symptoms of atopic dermatitis resolve.
Topical (Children ≥2–15 yr) Apply 0.03% ointment twice daily. Discontinue when signs/symptoms of atopic dermatitis resolve.

Potential Nursing Diagnoses

Risk for infection (Adverse Reactions)

Implementation

  • Do not use continuously for a long time.
  • Topical: Wash their hands before applying. Apply a thin layer of ointment twice daily to affected skin. Use smallest amount of ointment needed to control the signs and symptoms of eczema.

    • Advise patient to stop using the ointment when the signs/symptoms of atopic dermatitis (itching, rash, redness) go away.
    • Advise patient to limit sun exposure during therapy.
    • Advise patient of the risk of using topical tacrolimus during pregnancy.
