Generic Keflex Information

Introduction

Keflex is a short‑acting oral antibiotic whose active compound is Cephalexin. It belongs to the cephalosporin class of β‑lactam antibiotics and is used to treat a range of common bacterial infections. In Hong Kong, Keflex is listed under the Hong Kong Department of Health’s formulary for both community‑based and hospital‑based treatment of susceptible pathogens. The medication is manufactured by several international pharmaceutical firms; the most widely distributed brand is produced by Sandoz. Cephalexin is also employed for secondary indications such as prophylaxis before minor surgical procedures.

What is Keflex?

Keflex is the generic version of the original brand Keflex, containing the same active compound Cephalexin. Other well‑known brand names that contain Cephalexin include “Keflex”, “Keftab”, and “Cephalexin‑K”. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

• Classification: Cephalosporin (β‑lactam) antibiotic, first‑generation.
• Development: Derived from the fermentation product of Cephalosporium acremonium; first introduced in the early 196s.
• Manufacturer: Multiple approved manufacturers supply Keflex worldwide; in Hong Kong the product complies with local regulatory standards (HA HA‑GMP).

How Keflex Works

Cephalexin exerts its antibacterial effect by binding to penicillin‑binding proteins (PBPs) located on the bacterial cell wall. This binding inhibits the transpeptidation step of peptidoglycan synthesis, weakening the cell wall and causing osmotic lysis of susceptible Gram‑positive organisms (e.g., Staphylococcus aureus, Streptococcus pyogenes) and some Gram‑negative bacilli (e.g., Escherichia coli).

Key pharmacokinetic points:

• Onset of action: Plasma concentrations rise within 30 minutes after oral ingestion, providing therapeutic levels in 1–2 hours.
• Duration: Cephalexin has a half‑life of approximately 1 hour in adults with normal renal function, allowing dosing every 6–8 hours.
• Clearance: Renally eliminated unchanged; dose adjustment is required in impaired kidney function to avoid accumulation.

Conditions Treated with Keflex

Keflex is approved for the treatment of infections caused by Cephalexin‑susceptible bacteria, including:

• Uncomplicated skin and soft‑tissue infections (cellulitis, erysipelas, impetigo) – prevalent in Hong Kong’s humid climate, accounting for ~15 % of ambulatory visits.
• Upper respiratory tract infections (pharyngitis, tonsillitis, acute sinusitis) – common in densely populated districts.
• Urinary tract infections (cystitis) – frequently caused by E. coli strains sensitive to first‑generation cephalosporins.
• Otitis media – especially in pediatric populations; although the article focuses on adults, the same pathogen spectrum applies.
• Prophylaxis before minor dental or surgical procedures – recommended when patients are allergic to penicillins but not to cephalosporins.

The drug’s efficacy stems from its high activity against Gram‑positive cocci and its good oral bioavailability (≈ 90 %).

Who is Keflex For?

Keflex is suitable for adult patients who:

• Have a confirmed or strongly suspected bacterial infection with a pathogen known to be susceptible to first‑generation cephalosporins.
• Are not allergic to β‑lactam antibiotics (penicillins or cephalosporins).
• Possess normal or mildly impaired renal function; severe renal insufficiency requires dose reduction.

Clinical scenarios where Keflex is often recommended include:

• Community‑acquired skin infections in otherwise healthy adults.
• Acute uncomplicated urinary tract infections in non‑pregnant women.
• Early‑stage streptococcal pharyngitis where rapid antigen testing is positive.

Keflex may be inappropriate for:

• Patients with a known severe IgE‑mediated hypersensitivity to cephalosporins.
• Infections caused by β‑lactamase‑producing organisms (e.g., MRSA, Pseudomonas aeruginosa).
• Patients with significant renal impairment (eGFR < 30 mL/min) without dose adjustment.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, vomiting, mild abdominal cramping.
• Diarrhea – usually self‑limiting; may indicate alteration of gut flora.
• Transient rash – maculopapular eruptions that resolve after discontinuation.

Rare

• Clostridioides difficile colitis – colitis caused by overgrowth of C. difficile; presents with watery diarrhea and abdominal pain.
• Hepatobiliary enzyme elevations – mild increases in ALT/AST observed in < 1 % of patients.
• Peripheral eosinophilia – isolated eosinophil count rise without systemic symptoms.

Serious

• Anaphylaxis – rapid onset urticaria, bronchospasm, hypotension; requires emergency medical treatment.
• Serum sickness–like reaction – fever, arthralgia, urticarial rash occurring 7–10 days after exposure.
• Severe neutropenia – absolute neutrophil count < 500 cells/µL; warrants immediate cessation and hematology referral.

Drug–Drug Interactions

• Probenecid – reduces renal clearance of Cephalexin, increasing plasma concentrations; dose adjustment may be needed.
• Warfarin – occasional potentiation of anticoagulant effect; monitor INR if concurrent use is unavoidable.
• Oral contraceptives – no clinically relevant interaction, but patients should be advised to maintain regular contraception.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 250 mg orally every 6 hours or 500 mg every 12 hours for mild infections; up to 1 g every 6 hours for severe infections, not exceeding 4 g per day.
• Renal adjustment: For eGFR 30–50 mL/min, the dose may be halved; for eGFR < 30 mL/min, extend the dosing interval to every 12 hours.
• Missed dose: If a dose is forgotten and the next scheduled dose is at least 3 hours away, take the missed dose; otherwise skip it and resume the regular schedule. Do not double‑dose.
• Overdose: Acute overdose (e.g., > 10 g) may cause gastrointestinal irritation and transient renal dysfunction. Patients should seek medical evaluation; treatment is supportive, with hydration and monitoring of renal function.

Practical precautions:

• Take Keflex with or without food; food may slightly delay absorption but does not affect overall exposure.
• Avoid concurrent alcohol excess; while not directly interacting, alcohol can worsen gastrointestinal side effects.
• Inform the prescriber of any chronic diseases (e.g., diabetes, hepatic impairment) that may influence drug handling.

FAQ

• Is Keflex available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand “Keflex” is marketed by several companies, while generic Cephalexin tablets are produced by multiple licensed manufacturers. Both contain the same active ingredient and are approved by the Hong Kong Department of Health.

• Does Keflex require cold storage?
  No. Keflex should be stored at controlled room temperature (15 °C–30 °C), away from direct sunlight, heat, and moisture. Refrigeration is unnecessary and may cause condensation on tablets.

• What packaging does Keflex come in when ordered online?
  Tablets are typically supplied in blisters of 10 or 30 units, placed inside a sealed, tamper‑evident poly‑bag. The outer box includes the product name, strength, batch number, and expiry date.

• Can Keflex be safely imported into Hong Kong for personal use?
  Personal import of up to 30 days’ supply for a single individual is permitted under Hong Kong’s “personal medication” guidelines, provided the product is for a legitimate therapeutic purpose and is approved by the HA.

• Are there manufacturer warnings about Keflex specific to Asian populations?
  Manufacturers note that no ethnicity‑specific dosing adjustments are required. However, clinicians should monitor renal function in elderly Asian patients, as age‑related decline in glomerular filtration may affect clearance.

• Does Keflex have differences in formulation between regions (e.g., US vs EU vs Asia)?
  The tablet core composition is consistent (Cephalexin ≥ 94 % w/w). In the EU, a slight variation in inactive excipients (e.g., microcrystalline cellulose) exists, but this does not affect bioavailability.

• How long can I safely store Keflex after the expiry date?
  Cephalexin tablets may lose potency after the printed expiry date. For safety, discard any tablets older than the indicated date, especially if stored in humid environments.

• What is the history of Cephalexin development?
  Cephalexin was first isolated in 1962 as a semi‑synthetic derivative of cephalosporin C. It quickly became the prototype for first‑generation cephalosporins due to its oral stability and broad Gram‑positive coverage.

• How does Keflex compare to amoxicillin for skin infections?
  Both are β‑lactam antibiotics, but Keflex (a cephalosporin) has superior activity against β‑lactamase‑producing Staphylococcus strains. Amoxicillin is generally preferred for Streptococcus infections without β‑lactamase involvement.

• Will taking Keflex affect drug testing for employment?
  Cephalexin is not a prohibited substance in standard occupational drug screens. However, patients should disclose any medication use if required by employer policies.

• Can I travel with Keflex on an international flight?
  Yes, provided the medication is in its original packaging with a clear label. Carry a copy of the prescription or a physician’s note for customs inspection if requested.

• Is there a liquid formulation of Keflex for adults who cannot swallow tablets?
  A liquid suspension (250 mg/5 mL) is available in some regions but is not commonly marketed in Hong Kong for adults. Compounding pharmacies can prepare a suitable suspension if clinically indicated.

• What inactive ingredients are present in Keflex tablets?
  Typical excipients include microcrystalline cellulose, starch, magnesium stearate, and silicon dioxide. Patients with hypersensitivity to these components should consult their pharmacist.

Glossary

Cephalosporin

A class of β‑lactam antibiotics derived from the fungus Cephalosporium. First‑generation agents, such as Cephalexin, are effective primarily against Gram‑positive bacteria.

β‑lactamase

An enzyme produced by some bacteria that hydrolyzes the β‑lactam ring of antibiotics, rendering them inactive. Resistance to β‑lactam antibiotics often involves β‑lactamase production.

eGFR (estimated Glomerular Filtration Rate)

A calculated measure of kidney function based on serum creatinine, age, sex, and body size. It guides dosing adjustments for renally cleared drugs like Cephalexin.
