About Keftab

Generic Keftab (Cephalexin) is an oral antibiotic belonging to the first-generation cephalosporin class. It is prescribed for a range of bacterial infections, including skin-and-soft-tissue infections, uncomplicated urinary tract infections, and certain respiratory tract infections. The active ingredient, cephalexin, works by disrupting bacterial cell-wall synthesis, leading to rapid bacterial death. In Australia, this medication is available only with a prescription and is listed on the Pharmaceutical Benefits Scheme for eligible patients.

What is Generic Keftab (Cephalexin)?

Generic Keftab (Cephalexin) is a tablet formulation of the cephalosporin antibiotic cephalexin, marketed in strengths of 125 mg, 250 mg, 375 mg, 500 mg, and 750 mg. The product received approval from the Therapeutic Goods Administration (TGA) and is classified as a prescription-only medicine (S4). As a generic, it contains the same active molecule as brand-name cephalosporins and meets the same bio-equivalence standards, offering a cost-effective option for treating susceptible bacterial infections.

How Keftab Works

Cephalexin belongs to the β-lactam family. After oral ingestion, the drug is rapidly absorbed, reaching peak plasma concentrations within 30 minutes to 2 hours. It distributes widely in body fluids and tissues, with a half-life of approximately 1 hour in adults with normal renal function. The molecule binds irreversibly to penicillin-binding proteins (PBPs) located on the bacterial cell membrane. This binding inhibits the final transpeptidation step of peptidoglycan synthesis, weakening the cell wall and causing osmotic lysis of susceptible gram-positive organisms and some gram-negative bacteria. Because the drug is excreted largely unchanged in the urine, dose adjustments are required for patients with moderate to severe renal impairment.

Why Keftab is Used for Infection Conditions

  • Skin and soft-tissue infections - Staphylococcus aureus and Streptococcus pyogenes are primary pathogens. Cephalexin’s strong activity against these gram-positive cocci disrupts the bacterial cell wall, leading to swift clinical resolution. Guidelines from the Australian Therapeutic Guidelines place oral cephalexin as a first-line option for uncomplicated cellulitis and impetigo.
  • Uncomplicated urinary tract infections (UTIs) - Enteric bacteria such as E. coli are often sensitive to cephalexin. The drug attains high urinary concentrations, exceeding the minimum inhibitory concentrations (MICs) for common uropathogens, making it effective for cystitis. It is recommended as an alternative to trimethoprim-sulfamethoxazole when resistance is a concern.
  • Respiratory tract infections - For acute otitis media, sinusitis, and pharyngitis caused by susceptible streptococci, cephalexin provides reliable eradication. Its oral bioavailability (≈90 %) ensures therapeutic levels in the middle ear and sinus mucosa.
  • Bone and joint infections (early-stage osteomyelitis) - When the causative organism is a cephalexin-sensitive staphylococcus, the drug can be used intravenously or orally after initial parenteral therapy, facilitating outpatient management.
  • Prophylaxis for dental procedures - In patients with certain prosthetic joint implants, a single pre-operative dose of cephalexin reduces the risk of postoperative infection by inhibiting bacterial colonisation at the surgical site.

Off-Label and Investigational Uses of Keftab

Limited evidence from small randomized trials suggests cephalexin may be beneficial as prophylaxis against recurrent urinary tract infections in women with a history of uncomplicated cystitis. A 2021 pilot study (n = 58) reported a 30 % reduction in recurrence rates over a six-month period compared with placebo. These findings have not been incorporated into Australian prescribing guidelines, and the indication remains off-label. Off-label use should only be considered under the supervision of a qualified healthcare provider.

Is Keftab Right for You?

Keftab suits adult patients with infections caused by cephalexin-susceptible organisms and who have normal renal function. It is particularly advantageous for individuals seeking an oral regimen that can be taken multiple times a day without the need for injections. Elderly patients may require dose reduction if creatinine clearance falls below 30 mL/min. The medication is generally safe in pregnancy (Category B2 in Australia) but should be used only when clearly indicated. Persons with a known severe allergy to penicillins or other β-lactams should avoid Keftab, as cross-reactivity can occur. As noted in the medication information, hepatic impairment does not usually necessitate adjustment, but clinicians may monitor liver enzymes in patients with chronic liver disease.

Taking Keftab Effectively

  • Timing: For most infections, the prescribed dose is taken every 6 hours (four times daily) to maintain plasma concentrations above the MIC. If a dose is missed and the next scheduled dose is more than two hours away, take the missed dose and resume the regular schedule; do not double-dose.
  • Food and drink: Cephalexin can be taken with or without food; however, a high-fat meal may slightly delay absorption, which is clinically irrelevant for most infections.
  • Hydration: Adequate fluid intake helps ensure rapid renal excretion and reduces the risk of crystalluria, a rare complication when high doses are given.
  • Travel: When traveling abroad, pack enough tablets for the entire course plus a few extra in case of delays. Store the tablets at room temperature, away from moisture.
  • Interaction awareness: Antacids containing aluminium or magnesium can modestly reduce cephalexin absorption; separate dosing by at least two hours if both are required.

Understanding Side Effects and How to Manage Them

  • Gastrointestinal upset (nausea, diarrhea): These occur because the drug alters normal gut flora. Taking the tablet with food can lessen discomfort. If watery diarrhea persists beyond 48 hours, consider a probiotic supplement or contact a clinician to rule out C. difficile infection.
  • Allergic reactions: Rash, urticaria, or mild itching stem from the immune system recognizing the β-lactam ring. Antihistamines (e.g., cetirizine) may control symptoms, but swelling of the face, lips, or throat demands immediate medical attention-a potential anaphylactic reaction.
  • Renal toxicity: Rarely, high concentrations can cause interstitial nephritis. Monitor urine output and report flank pain or sudden swelling.
  • Hematologic effects: Transient eosinophilia or neutropenia may appear, especially with prolonged use. Routine blood counts are advisable for courses exceeding two weeks.

Frequently Asked Questions

  • How quickly will I feel better after starting Keftab? Most patients notice symptom improvement within 48-72 hours as bacterial load declines. Complete eradication generally requires the full prescribed course, even if you feel better sooner.

  • Can I take Keftab with other antibiotics? Concurrent use is usually unnecessary and may increase the risk of side effects. If combination therapy is deemed essential-such as adding metronidazole for mixed anaerobic infections-your prescriber will adjust dosages accordingly.

  • Is it safe to use Keftab for a child’s ear infection? Cephalexin is approved for pediatric use down to 6 months of age at weight-adjusted doses. However, dosing for children differs from adult tablet strengths; liquid formulations are preferred for precise dosing.

  • Will Keftab affect birth control pills? Unlike some antibiotics, cephalexin does not interfere with hormonal contraceptive efficacy. Maintaining regular pill intake remains important.

  • What should I do if I miss a dose while on a weekend? Take the missed dose as soon as you remember, provided at least two hours remain before the next scheduled dose. Otherwise, skip the missed dose and continue with your regular timetable.

  • How does Keftab compare to amoxicillin for sinusitis? Both are β-lactams, but amoxicillin has broader activity against H. influenzae and M. catarrhalis. Cephalexin is preferred when the suspected pathogen is a penicillin-susceptible streptococcus or when a patient has a documented amoxicillin allergy.

  • Can I take Keftab while on a sodium-restricted diet? Cephalexin tablets contain minimal sodium, typically less than 10 mg per dose, making them compatible with most low-sodium regimens.

  • Do I need to avoid alcohol while taking Keftab? No direct interaction exists, but excessive alcohol can exacerbate gastrointestinal side effects and impair immune function, potentially slowing recovery.

  • Is it necessary to complete the full course even if symptoms resolve? Yes. Stopping early may allow surviving bacteria to regrow, increasing the risk of resistance and relapse.

  • What if I develop a rash after the first tablet? A mild rash may be a harmless hypersensitivity reaction, but any skin change warrants a prompt call to your healthcare provider to assess the need for discontinuation.
