Keflex

Cephalexin, the active ingredient in Keflex, is a first‑generation cephalosporin presented as an oral tablet for oral use. It treats a range of bacterial infections, including skin and soft‑tissue, respiratory, urinary, and bone or joint infections, and is prescribed for adults and children when appropriate.

GNH USA supplies Keflex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a focus on reliable quality, regulatory compliance and timely global logistics, and competitive pricing across major markets.

Cephalexin is indicated for bacterial infections affecting several organ systems.

- Skin and soft‑tissue infections: effective against cellulitis, impetigo and wound infections caused by susceptible bacteria. - Respiratory tract infections: treats acute bacterial sinusitis, tonsillitis and community‑acquired pneumonia when caused by susceptible organisms. - Urinary tract infections: used for uncomplicated cystitis and pyelonephritis caused by susceptible strains. - Bone and joint infections: employed in osteomyelitis and septic arthritis as part of combination therapy for susceptible pathogens.

Cephalexin may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea: mild stomach upset often occurring after the dose. - Diarrhea: loose stools that may be self‑limiting. - Rash: skin redness or itching without systemic involvement. - Headache: mild to moderate head discomfort. - Vomiting: occasional emesis after ingestion. - Abdominal pain: cramping or discomfort in the stomach area.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction with breathing difficulty and swelling. - Clostridioides difficile‑associated colitis: severe diarrhea with possible fever. - Stevens‑Johnson syndrome: rare skin blistering and mucosal involvement. - Blood dyscrasias: abnormal blood counts such as neutropenia or agranulocytosis. - Liver enzyme elevation: signs of hepatic stress detectable in labs.

Before prescribing Cephalexin, clinicians should consider several safety factors.

- Renal impairment: dose adjustment may be required in patients with reduced kidney function. - Allergy to beta‑lactams: avoid use in individuals with known hypersensitivity to penicillins or cephalosporins. - Pregnancy: use only if the potential benefit justifies the potential risk to the fetus. - Concomitant anticoagulants: monitor INR or PT values as Cephalexin may enhance anticoagulant effects. - Prolonged therapy: watch for superinfection or overgrowth of non‑susceptible organisms. - Store at room temperature: keep in the original pack, protect from moisture and excessive heat.

Cephalexin can interact with other medicines, altering its effectiveness or safety.

Major Interactions (Avoid): - Probenecid: increases serum Cephalexin concentrations, raising toxicity risk. - Warfarin: may potentiate anticoagulant effect, requiring closer INR monitoring. - Oral contraceptives: may reduce hormonal efficacy, increasing risk of unintended pregnancy.

Moderate Interactions (Monitor Closely): - Aminoglycosides: additive nephrotoxicity potential, especially in renal‑compromised patients. - Loop diuretics: may increase risk of renal impairment when combined. - Allopurinol: heightened risk of rash, including severe cutaneous reactions.
