Generic Cephalexin Information

Introduction

Cephalexin is a widely used oral antibiotic that belongs to the cephalosporin class (first‑generation). In the United Kingdom it is prescribed for a range of bacterial infections of the skin, respiratory tract, urinary system and bone. The active compound is Cephalexin, and it is marketed under the broad medication group Antibiotics. Health‑care professionals select it for its reliable activity against Gram‑positive bacteria and some Gram‑negative organisms, and for its generally favorable safety profile compared with older penicillins.

What is Cephalexin?

Cephalexin is a synthetic β‑lactam antibiotic derived from the core structure of cephalosporin C. It was first developed in the 196s by Eli Lilly and later commercialised worldwide under the brand name Keflex. Other well‑known brand names include Ceporex, Zyvox (in certain formulations) and Rawson.

Cephalexin is the generic version of Keflex, containing the same active compound, Cephalexin. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for patients who need an affordable, high‑quality antibiotic.

How Cephalexin Works

Cephalexin exerts its antibacterial effect by binding to penicillin‑binding proteins (PBPs) located on the bacterial cell wall. This inhibits the final stages of peptidoglycan synthesis, weakening the wall and causing the bacterium to lyse under osmotic pressure. The drug is bactericidal, meaning it kills susceptible organisms rather than merely inhibiting their growth.

After oral ingestion, Cephalexin is absorbed rapidly, reaching peak plasma concentrations within 30–60 minutes. It distributes widely to most tissues and fluids, including skin, bone, and the urinary tract. The drug is eliminated primarily unchanged by the kidneys, with a half‑life of approximately 1 hour in adults with normal renal function, allowing for convenient twice‑daily dosing.

Conditions Treated with Cephalexin

• Skin and Soft‑Tissue Infections – cellulitis, erysipelas, impetigo, infected wounds, and cutaneous abscesses caused by Staphylococcus aureus (penicillin‑susceptible) or Streptococcus pyogenes.
• Respiratory Tract Infections – uncomplicated acute bacterial sinusitis, streptococcal pharyngitis, and community‑acquired pneumonia where the likely pathogens are susceptible to first‑generation cephalosporins.
• Urinary Tract Infections (UTIs) – cystitis and uncomplicated pyelonephritis caused by Escherichia coli and other susceptible Gram‑negative bacilli.
• Bone and Joint Infections – early‑stage osteomyelitis or septic arthritis when the causative organism is known to be sensitive.
• Dental and Oral Infections – prophylaxis or treatment of post‑extraction infections and periodontal abscesses.

In the United Kingdom these indications align with the British National Formulary (BNF) recommendations and are supported by clinical trials demonstrating comparable cure rates to amoxicillin for many community infections. The drug’s activity against common resistant strains such as methicillin‑susceptible Staphylococcus aureus (MSSA) makes it a valuable first‑line option.

Who is Cephalexin For?

Cephalexin is appropriate for adult patients (≥ 18 years) who present with bacterial infections that are known or strongly suspected to be caused by cephalosporin‑susceptible organisms. Typical scenarios include:

• Individuals with uncomplicated skin infections (e.g., cellulitis) that have not responded to topical therapy.
• Patients diagnosed with streptococcal pharyngitis confirmed by rapid antigen testing or culture.
• Adults with uncomplicated urinary tract infection where culture shows susceptibility.
• Those requiring short‑course prophylaxis after minor oral surgery.

Cephalexin is not recommended for patients with a documented severe allergy to penicillins or other β‑lactam antibiotics, as cross‑reactivity can occur (approximately 5‑10 %). It is also unsuitable for infections caused by β‑lactamase‑producing Staphylococcus aureus (MRSA), Enterococcus species, or Pseudomonas aeruginosa, which are inherently resistant. Renal impairment necessitates dose adjustment; therefore, individuals with chronic kidney disease should be evaluated before initiation.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, vomiting, abdominal pain, and mild diarrhoea.
• Transient rash – maculopapular eruptions that usually resolve without intervention.
• Taste disturbance – a metallic or bitter taste reported by some patients.
• Headache – mild, self‑limiting headache is frequently recorded.

Rare

• Clostridioides difficile‑associated diarrhoea – can occur after broad‑spectrum antibiotic use.
• Hepatic enzyme elevation – transient increase in ALT/AST without clinical hepatitis.
• Peripheral eosinophilia – occasional rise in eosinophil count, generally asymptomatic.
• Positive Coombs test – may be detected without haemolytic anaemia.

Serious

• Severe allergic reactions – anaphylaxis, angio‑oedema, or urticaria requiring emergency treatment.
• Serum‑sickness‑like reaction – fever, arthralgia, and rash appearing 1–2 weeks after exposure.
• Acute interstitial nephritis – rare but may manifest with reduced urine output and renal dysfunction.
• Seizures – especially in patients with renal failure receiving high doses.

Drug–Drug Interactions

• Probenecid – reduces renal excretion of Cephalexin, increasing plasma concentrations and risk of toxicity.
• Warfarin – may enhance anticoagulant effect; INR should be monitored when initiating or stopping Cephalexin.
• Oral contraceptives – theoretical reduction in efficacy; backup contraception is advisable.
• Diuretics (e.g., furosemide) – potentiates the risk of renal crystal formation, especially in dehydrated patients.

Patients should disclose all current medications, including over‑the‑counter supplements, to their health‑care provider before starting Cephalexin.

Practical Use: Dosing, Missed Dose, Overdose

Standard adult dosing (general guidance only):

• Skin, bone, and urinary infections: 250 mg–500 mg every 6 hours (four times daily).
• Respiratory and dental infections: 500 mg every 12 hours (twice daily).

The total daily dose usually does not exceed 4 g. Treatment duration varies by infection—typically 5–7 days for uncomplicated skin infections, up to 14 days for bone involvement.

Missed dose – If a dose is forgotten and it is less than 4 hours before the next scheduled dose, take the missed tablet immediately and continue with the regular schedule. Do not double the dose to “catch up.”

Overdose – Symptoms may include nausea, vomiting, dizziness, and abdominal discomfort. In severe cases, renal impairment can develop. Prompt medical evaluation is essential; activated charcoal may be considered if presentation is early. Supportive care, including hydration and monitoring of renal function, is the mainstay of treatment.

Food and alcohol – Cephalexin can be taken with or without food; a light meal may reduce mild gastrointestinal upset. Alcohol does not interact directly with the drug but excessive intake can worsen liver injury and dehydration, increasing the risk of kidney complications.

Renal considerations – Patients with creatinine clearance < 30 mL/min require dose reduction (e.g., 250 mg every 12 hours) to avoid accumulation.
