Generic Keftab Information

Introduction

Keftab is an oral antibiotic whose active ingredient is cephalexin, a member of the β‑lactam class known as first‑generation cephalosporins. In Hong Kong, cephalexin‑containing products are used to treat a range of common bacterial infections, including skin and soft‑tissue infections, respiratory tract infections, and urinary tract infections. Keftab is manufactured by a licensed pharmaceutical company that complies with the standards set by the Hong Kong Department of Health. The medication belongs to the broader antibiotic group, which is essential for controlling bacterial disease when used appropriately.

What is Keftab?

Keftab is a tablet formulation that delivers a fixed dose of cephalexin, a synthetic β‑lactam antibiotic. The drug is classified as a broad‑spectrum, gram‑positive‑predominant antibacterial agent. Cephalexin was first synthesized in the 196s and has since become a cornerstone of outpatient antimicrobial therapy worldwide. While Keftab itself does not have widely known brand‑name counterpart, cephalexin is marketed under several well‑established brands such as Keflex, Ceporex, and Cefalexin‑M. These reference names help patients and clinicians recognize the active compound across different markets. Keftab provides the same pharmacological effect as those brand‑name products, offering a cost‑effective alternative for patients in Hong Kong.

How Keftab 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 it to rupture under osmotic pressure. The result is rapid bacterial cell lysis. Because the mechanism targets a structure that is absent in human cells, cephalexin displays a high therapeutic index. Onset of action typically occurs within one to two hours after oral ingestion, and the drug’s half‑life in healthy adults is approximately one hour, allowing for twice‑daily dosing to maintain effective plasma concentrations. Renal excretion eliminates the majority of the dose unchanged, which informs dose adjustments in patients with impaired kidney function.

Conditions Treated with Keftab

• Uncomplicated Skin and Soft‑Tissue Infections (SSTIs): Cellulitis, impetigo, and infected eczema caused primarily by Staphylococcus aureus (methicillin‑sensitive) or Streptococcus pyogenes. In Hong Kong, SSTIs account for a substantial proportion of primary‑care visits, especially during humid months.
• **Acute Bacterial Pharyng When streptococcal infection is confirmed, cephalexin offers an alternative to macrolides for patients with penicillin allergy (excluding severe β‑lactam allergy).
• Community‑Acquired Pneumonia (Mild‑to‑Moderate): Cephalexin covers common atypical pathogens such as Streptococcus pneumoniae when they are susceptible, making it suitable for outpatient management.
• Uncomplicated Urinary Tract Infections (UTIs): Particularly in women, where Escherichia coli strains remain sensitive to cephalexin. The prevalence of UTIs in Hong Kong’s adult population mirrors global trends, highlighting the need for readily available oral agents.
• Prophylaxis for Surgical Procedures: Short courses before minor skin or dental surgeries reduce postoperative infection risk, provided the surgical site flora are susceptible.

Who is Keftab For?

Keftab is appropriate for adult patients who require an oral antibacterial agent for infections known to be susceptible to cephalexin. Ideal candidates include:

• Individuals with mild to moderate SSTIs without indication for intravenous therapy.
• Adults with confirmed streptococcal pharyngitis who are not allergic to β‑lactams.
• Patients with uncomplicated UTIs where culture data (or local resistance patterns) favor cephalexin sensitivity.
• Those undergoing minor surgical or dental procedures where prophylactic coverage is indicated.

Keftab should be avoided or used with caution in:

• Patients with a documented severe hypersensitivity reaction to penicillins or other cephalosporins (e.g., anaphylaxis).
• Individuals with profound renal impairment (creatinine clearance <30 mL/min) unless dose‑adjusted.
• Pregnant or breastfeeding women only when the expected benefit outweighs potential risk, as safety data are limited but generally reassuring.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset (nausea, vomiting, abdominal cramping)
• Diarrhea, which may be mild or self‑limited
• Transient rash or pruritus

Rare

• Clostridioides difficile–associated colitis, presenting with profuse watery diarrhea and abdominal pain
• Hepatobiliary disturbances such as elevated liver enzymes or cholestatic jaundice
• Hematologic changes including eosinophilia or leukopenia

Serious

• Severe hypersensitivity reactions (e.g., Stevens‑Johnson syndrome, toxic epidermal necrolysis)
• Anaphylactic shock with rapid onset respiratory compromise
• Acute interstitial nephritis, characterized by flank pain, hematuria, and rising serum creatinine

Drug–Drug Interactions

• Probenecid: Decreases renal clearance of cephalexin, raising plasma levels; dose adjustment may be required.
• Warfarin: Cephalexin can potentiate anticoagulant effect; monitor INR more frequently during co‑administration.
• Oral contraceptives: Although evidence is limited, β‑lactam antibiotics have been reported to reduce contraceptive efficacy; additional non‑hormonal contraception is advisable.
• Renal‑excreting drugs (e.g., aminoglycosides): Additive nephrotoxicity potential; monitor renal function.

Practical Use: Dosing, Missed Dose, Overdose

• Standard Adult Dosing: 250 mg to 500 mg orally every 6 hours for most infections; severe infections may require 1 g every 6 hours. The exact dose and duration depend on infection type, severity, and patient renal function.
• Missed Dose: Take the missed dose as soon as remembered if it is within 4 hours of the scheduled time. Otherwise, skip the missed dose and resume the regular schedule; do not double‑dose.
• Overdose: Symptoms may include nausea, vomiting, abdominal pain, and, rarely, seizures due to high plasma concentrations. Management is supportive; activated charcoal may be considered if presentation is within one hour of ingestion. Hemodialysis is ineffective because cephalexin is not highly protein‑bound.
• Food & Alcohol: Cephalexin can be taken with or without food; a meal may reduce gastrointestinal irritation. Alcohol does not interact directly, but excessive intake may exacerbate gastrointestinal side effects.
• Comorbidities: In patients with reduced creatinine clearance, dosing intervals should be extended (e.g., every 12 hours) to avoid accumulation. Patients with hepatic disease generally do not require adjustment, as cephalexin is minimally metabolized by the liver.
