Cefalexin is used to treat bacterial infections affecting several organ systems. - Skin and soft‑tissue infections: Reduces bacterial load and promotes healing of cellulitis, impetigo and wound infections. - Urinary tract infections: Eradicates susceptible uropathogens, relieving dysuria and preventing complications. - Respiratory tract infections: Controls pathogens in acute bronchitis, pharyngitis and sinusitis. - Bone and joint infections: Provides bactericidal activity against organisms causing osteomyelitis and septic arthritis. - Otitis media: Treats middle‑ear infections caused by susceptible bacteria.

Cefalexin may cause adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Diarrhea: Loose stools occurring during therapy. - Nausea: Feeling of unease or upset stomach. - Vomiting: Involuntary expulsion of stomach contents. - Rash: Mild skin redness or itching.

Serious or Rare Side Effects: - Anaphylaxis: Severe, potentially life‑threatening allergic reaction. - Clostridioides difficile‑associated colitis: Severe inflammation of the colon. - Stevens‑Johnson syndrome: Rare, serious skin and mucous membrane disorder.

When prescribing cefalexin, clinicians should consider several precautionary measures to ensure safe use. - Assess renal function: Adjust dose in patients with impaired kidney function. - Review allergy history: Avoid in individuals with known penicillin or cephalosporin hypersensitivity. - Monitor for superinfection: Prolonged therapy may lead to fungal overgrowth. - Use caution in pregnancy: Category B, but benefits must outweigh potential risks. - Store at room temperature: Keep in the original pack, protect from moisture and heat.

Cefalexin can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - Probenecid: Decreases renal excretion, increasing cefalexin plasma levels. - Warfarin: May enhance anticoagulant effect, increasing bleeding risk. - Oral contraceptives: Potential reduction in contraceptive efficacy.

Moderate Interactions (Monitor Closely): - Aminoglycosides: Combined use may increase nephrotoxicity. - Antacids containing aluminum or magnesium: Can reduce cefalexin absorption. - Metformin: May raise metformin levels in patients with renal impairment.
