Contraindications
Hypersensitivity. History of acute severe allergic reaction to any other β-lactam active substances (eg, cephalosporin, monobactam or carbapenem).
Special Precautions
Hypersensitivity to penicillins, other β-lactam agents (eg, cephalosporin, monobactam or carbapenem) & other allergens. May cause severe cutaneous adverse reaction eg, SJS & TEN. Life threatening severe, persistent diarrhoea may manifest antibiotic-induced pseudomembranous colitis. Super-infections may result in emergence of resistant organisms. Leukopenia & neutropenia may occur during prolonged therapy. Monitor closely for skin rash (discontinue if lesions progress); serum levels of MTX to avoid toxicity. Perform assessment of hematopoietic function periodically; appropriate coagulation tests more frequently. Monitor serum levels of MTX to avoid toxicity. Abnormalities of coagulation tests, eg, clotting time, platelet aggregation & prothrombin time associated in bleeding manifestations; discontinue antibiotic & initiate therapy.
Adverse Reactions
Diarrhoea. Candida infection; thrombocytopenia, anaemia; decreased blood albumin, decreased total protein; insomnia; headache; hypotension, thrombophlebitis, phlebitis, flushing; abdominal pain, vomiting, nausea, constipation, dyspepsia; rash, pruritus; pyrexia, inj site reaction; increased ALT, AST, blood creatinine, blood alkaline phosphatase, blood urea; decreased total protein, +ve direct Coombs test. Prolonged aPTT.
Drug Interactions
Concomitant use may lead to prolongation of neuromuscular blockade of vecuronium; increase incidence of acute kidney injury w/ vancomycin; reduce excretion of MTX. May affect blood coagulation system including thrombocyte function. Produces longer t½ & lower renal clearance w/ probenecid.
