Cefalexin (Keflex) is a broad‑spectrum cephalosporin antibiotic used to treat infections caused by susceptible bacteria.

- Skin and soft tissue infections: Effective in eliminating common Gram‑positive organisms causing cellulitis, impetigo and wound infections. - Respiratory tract infections: Treats acute bronchitis, sinusitis and community‑acquired pneumonia caused by susceptible strains. - Urinary tract infections: Eradicates Escherichia coli and other pathogens responsible for uncomplicated cystitis and pyelonephritis.

Cefalexin may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhea: often self‑limiting, may be watery. - Rash: non‑specific skin eruption. - Headache: transient and mild.

Serious or Rare Side Effects: - Clostridioides difficile‑associated diarrhea: severe colitis requiring medical attention. - Anaphylaxis: rapid onset of severe allergic reaction. - Stevens‑Johnson syndrome: extensive skin detachment and mucosal involvement. - Blood dyscrasias: neutropenia, thrombocytopenia, or hemolytic anemia. - Hepatic enzyme elevation: potential liver function abnormalities. - Renal impairment: reduced kidney function in susceptible individuals.

Before initiating therapy with Cefalexin, consider the following precautions.

- Assess renal function: adjust dose in patients with impaired clearance. - Monitor for allergic reactions: discontinue if signs of hypersensitivity appear. - Avoid use in patients with known cephalosporin allergy: cross‑reactivity may occur. - Use with caution in pregnant or breastfeeding women: weigh benefits against potential risks. - Store at room temperature: keep in the original container, protect from moisture and heat.

Cefalexin can interact with several medicines; awareness of the interaction level helps manage risk.

Major Interactions (Avoid): - Probenecid: may increase cefalexin plasma concentrations, raising toxicity risk. - Anticoagulants (e.g., warfarin): may enhance anticoagulant effect, requiring INR monitoring. - Live bacterial vaccines: antibiotic therapy may reduce vaccine efficacy.

Moderate Interactions (Monitor Closely): - Oral contraceptives: possible reduction in effectiveness; advise backup contraception. - Diuretics (e.g., furosemide): may increase risk of nephrotoxicity. - Aminoglycosides: additive nephrotoxic potential when used together.
