About Keflex: What It Is and How It Works

Keflex, generically known as cephalexin, is a first-generation cephalosporin antibiotic. Available in Canada as both branded and generic products, it disrupts the bacterial cell wall synthesis, ultimately leading to the death of susceptible bacteria. Keflex is commonly relied upon for skin, urinary tract, respiratory, ear, and bone infections. Its effectiveness, low resistance profile, and generally well-tolerated nature have secured its inclusion in major Canadian clinical guidelines.

  • Therapeutic class: Antibiotic (Cephalosporin, first generation)
  • Health Canada DPD status: Approved
  • Available dosages in Canada: 250mg, 500mg capsules
  • Price point: Starting from CAD $0.65 per capsule (250mg) and CAD $0.89 per capsule (500mg) — actual pricing starts as low as CAD $0.65, with bulk savings available

The bactericidal action of cephalexin makes it particularly useful in eradicating common skin flora, as well as numerous respiratory and urinary tract pathogens, including Staphylococcus aureus (MSSA), Streptococcus pneumoniae, and Escherichia coli. It is not effective against MRSA or organisms producing extended-spectrum beta-lactamases (ESBLs).

Who Benefits From Keflex?

Keflex is prescribed widely in Canada for both adults and children who have bacterial infections appropriate for cephalexin’s spectrum. Consideration is given to allergy history and specific infection type. Below, see where Canadians most commonly benefit from Keflex therapy:

  • Skin & soft tissue infections: Cellulitis, infected wounds, and impetigo in otherwise healthy people.
  • Uncomplicated urinary tract infections (UTIs): Especially in non-pregnant women, where local resistance is low.
  • Pharyngitis & tonsillitis: Cephalexin serves as a second-line agent for strep throat in patients unable to take penicillins.
  • Bone/joint infections: Occasionally used for mild cases or when IV therapy is not needed.
  • Pediatric use: Approved for use in children, with dose adjustments based on weight.

Keflex is not first-line for pneumonia, meningitis, or known/suspected MRSA infections. People with known hypersensitivity to cephalosporins or severe penicillin allergies should consult a licensed physician or pharmacist before use.

Keflex Dosage Titration Guide

Precise dosing of cephalexin is critical for therapeutic success and safety. It is always best to follow dose and duration recommendations tailored by your Canadian prescriber. The following table offers a general guideline for common infections:

Cephalexin (Keflex) Adult Dosage Reference
Infection Type Common Adult Dose Typical Duration Comments
Skin/Soft Tissue Infection 500mg every 6-12 hours 5–10 days May adjust in severe cases
Uncomplicated UTI 500mg every 12 hours 7–14 days Check local resistance
Strep Throat 500mg every 12 hours 10 days Penicillin-allergic patients
Pediatric Dosing 25–50mg/kg/day in divided doses 5–10 days Consult paediatrician for exact dosing

Cephalexin should be taken at evenly spaced intervals for optimal effect. Capsules may be swallowed whole with water, with or without food. Dosage adjustments may be necessary in those with reduced kidney function—a pharmacist can verify appropriateness for you.

Keflex Safety Profile & Side Effects

While Keflex’s record for tolerability is strong, understanding potential side effects and warning signs is integral to safe use:

  • Common, mild side effects: Diarrhoea, mild nausea, upset stomach, or temporary rash
  • Rare/serious reactions: Severe allergic symptoms, such as facial swelling or difficulty breathing—seek emergent care if these occur
  • Allergic cross-reactivity: About 10% of people with penicillin allergy may react; review your history with a Canadian pharmacist or prescriber before starting cephalexin
  • C. difficile warning: As with all antibiotics, Keflex may rarely cause severe diarrhoea due to Clostridioides difficile. Persistent or severe diarrhoea warrants medical review

Keflex should only be used for infections that are likely bacterial and responsive to cephalexin. Unnecessary use increases resistance risk and can worsen side effect likelihood. Always finish the prescribed course—even if symptoms resolve early—unless advised otherwise by a healthcare professional.

Potential Drug Interactions With Cephalexin

Despite Keflex’s favourable drug-drug interaction profile compared to some other antibiotics, always share your medication list with your dispensing pharmacy. Key considerations include:

  • Probenecid: May increase cephalexin blood levels and risk of side effects
  • Metformin: Rarely, cephalexin may raise metformin concentrations; monitor for increased side effects, especially with reduced kidney function
  • Live vaccines: As a general precaution, antibiotics may interfere with the efficacy of some oral live vaccines (e.g., typhoid oral vaccine)

Over-the-counter medications, vitamins, and herbal supplements typically don’t interact with cephalexin but check with your pharmacist if uncertain. Alcohol is not contraindicated with cephalexin but may worsen possible gastrointestinal side effects.

Proper Storage & Handling of Keflex

Good medication storage protects potency and prevents accidental misuse:

  • Store Keflex capsules at room temperature (15°C – 30°C)
  • Keep in original packaging: Protects from moisture and light
  • Keep out of reach of children and pets
  • Do not use past the expiry date on the label
  • For liquid formulations, refrigerate and discard after 14 days, unless otherwise directed

If you have unused or expired medication, follow your city or province’s guidance for safe disposal—many pharmacies in Canada offer take-back programs for antibiotics and other drug products.

Keflex vs. Other Antibiotics: How Does It Compare?

Selecting the most appropriate antibiotic depends on infection type, local resistance, allergies, and patient-specific factors. Below is a comparison of cephalexin versus a few common alternatives often dispensed in Canadian pharmacies:

Antibiotic Alternatives for Skin/Urinary Infections
Medication Typical Use Major Contraindications Generic Available Typical CAD Cost (30 tabs/caps)
Keflex (Cephalexin) Skin, UTI, Strep Throat Cephalosporin allergy Yes $37–$40
Amoxicillin Strep, ear/chest/skin infection Penicillin allergy Yes $19–$24
Ciprofloxacin UTI (resistant cases) Pediatrics, pregnancy, tendon disorders Yes $34–$50
Clindamycin MRSA/cellulitis Clindamycin allergy, C. difficile risk Yes $55–$80

While cephalexin is suitable for many common first-line infections, your provider may choose alternatives based on individual tolerance, suspected drug resistance, or infection location. Whenever possible, request a review of all antibiotic choices and their suitability for your case.
