Vancomycin and teicoplanin are glycopeptide antibiotics used to treat serious gram-positive infections like MRSA. Vancomycin is administered intravenously or orally to treat infections and dosed based on creatinine clearance, age, and weight. Teicoplanin can be given intravenously, intramuscularly, or orally once daily after a loading dose with dosing based on creatinine clearance, age, and weight. Both antibiotics require monitoring for nephrotoxicity and ototoxicity as side effects and have drug interactions with aminoglycosides and diuretics. They are supplied as powders for reconstitution and stored below 25°C.
