Precautions
Serious hypersensitivity (anaphylactic) reactions: Prior to use, inquire regarding history of hypersensitivity to beta-lactam antibacterial drugs. Discontinue the drug if signs or symptoms of an allergic reaction occur and institute supportive measures.
Clostridium difficile-associated diarrhea (CDAD): Evaluate if diarrhea occurs.
Direct Coomb’s Test Seroconversion: If anemia develops during or after cephalexin therapy, evaluate for drug-induced hemolytic anemia.
Seizure Potential: Use lower dose in patients with renal impairment.
Pregnancy-Lactation
Pregnancy
There are no adequate and well-controlled studies
Available data from published epidemiologic studies and pharmacovigilance case reports over several decades with cephalosporin use, use in pregnant women have not established drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes
Animal data
Animal reproduction studies with mice and rats using oral doses of cephalexin that are 0.6- and 1.2-times the maximum recommended human dose (MRHD) based on body surface area during organogenesis revealed no evidence of harm to the fetus; estimated background risk of major birth defects and miscarriage for indicated population is unknown
Lactation
Data from a published clinical lactation study reports that cephalexin is present in human milk; relative infant dose (RID) is considered to be <1% of maternal weight adjusted dose; there are no data on effects of cephalexin on breastfed child or on milk production
Development of health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from therapy or from underlying maternal condition
Interactions
Concurrent use w/ metfromin may result to fatal lactic acidosis.
May enhance the anticoagulant effect of vit K antagonists (e.g. warfarin).
Increased risk of nephrotoxicity w/ potent diuretics (e.g. ethacrynic acid, furosemide) and other potentially nephrotoxic antibiotics (e.g. aminoglycosides, polymyxin, colistin).
Prothrombin time may be prolonged when used concomitantly w/ oral anticoagulants.
May reduce the effects of OCs.
Hypokalaemia may result from concomitant use of cefalexin and cytotoxic drugs for leukaemia.
Uricosuric drugs (e.g. probenecid) may suppress renal excretion, resulting to increased plasma levels of cefalexin.
May diminish the therapeutic effect of Na picosulfate, BCG and typhoid vaccine.
May reduce serum level w/ multivitamins/minerals.
Contraindicated (0)
Serious (4)
BCG vaccine live
cholera vaccine
microbiota oral

Mechanism of Action
Cefalexin binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.
