Keftab
Keftab
- In our pharmacy, you can purchase Keftab (cephalexin) without a prescription, with worldwide delivery in 7-14 days. Discreet and temperature-controlled packaging.
- Keftab treats bacterial infections like respiratory, skin, and urinary tract infections. It inhibits bacterial cell wall synthesis to kill bacteria.
- The usual adult dose is 250–500mg every 6–12 hours, adjusted for infection severity and kidney function. Children take weight-based doses.
- Administered orally as tablets, capsules, or suspensions (liquid form for pediatric use).
- Effects begin within 1–2 hours of ingestion, with noticeable symptom improvement typically within 24–48 hours.
- The duration of antibacterial action requires doses every 6–12 hours to maintain effective levels throughout treatment.
- Avoid alcohol during treatment, as it may increase nausea and reduce the drug’s effectiveness against infections.
- Common side effects include diarrhea, nausea, vomiting, stomach discomfort, and rash.

Basic Keftab Information
| Attribute | Details |
|---|---|
| INN (International Nonproprietary Name) | Cephalexin |
| Brand names in Australia | Keftab®, Keflex® |
| ATC Code | J01DB01 |
| Forms & Dosages | Tablets (250mg/500mg/1g), Oral suspension (125mg/5mL) |
| Primary Manufacturers | Sandoz (Novartis), Lupin Pharmaceuticals |
| Registration Status | Prescription-only (S4) |
| Classification | First-generation cephalosporin antibiotic |
Generic versions remain available through the Pharmaceutical Benefits Scheme, though Keftab remains preferred for specific therapeutic situations throughout Australian healthcare settings.
Pharmacological Mechanisms of Action
Keftab operates by disrupting bacterial cell wall formation. Its molecular structure binds to penicillin-binding proteins within the bacterial membrane. This halts the final cross-linking stage essential for structural integrity.
Coverage spectrum includes:
- Gram-positive cocci including streptococci species
- Certain staphylococcus strains (excluding MRSA)
| Oral absorption rate | Approximately 95% bioavailability |
| Peak plasma concentration | Occurs within 60 minutes post-administration |
| Elimination pathway | Renal excretion (90% unchanged) |
Dosing intervals require precision since efficacy depends on time-dependent bacterial killing rather than peak concentration levels.
Therapeutic Approved Indications
Therapeutic Goods Administration (TGA) approves Keftab for specific infectious conditions in Australian clinical practice. Primary medically accepted usages include respiratory tract infections like streptococcal pharyngitis and lower respiratory complications. Bacterial skin infections and uncomplicated urinary tract infections caused by susceptible E. coli strains also feature among TGA-sanctioned applications.
Treatment protocols vary significantly across patient demographics:
- Children under 12: First-line management option for acute otitis media cases
- Elderly patients: Preferred when renal clearance concerns limit alternative antibiotics
- Pregnancy cases: Category A safety rating makes it the safest antimicrobial choice
Clinicians must note the limitation against MRSA infections and penicillin-resistant pneumococcal strains, necessitating pre-treatment sensitivity testing in ambiguous presentations.
Unapproved Off-Label Applications
Certain evidence-supported off-label uses occur in Australian clinical settings. Dental prophylaxis during high-risk invasive procedures represents the most frequent unapproved administration. Mastitis treatment in breastfeeding mothers sometimes incorporates cephalexin despite absence in official TGA guidance. Some practitioners employ it controversially for COPD exacerbations and surgical prophylaxis scenarios.
Recent Australian research demonstrates emerging applications including adjunctive Lyme disease therapy, although regulatory approval remains pending. The Kirby Institute's 2023 study indicated potential benefits but requires extensive validation before TGA endorsement. Clinical discretion remains essential when considering therapies beyond approved indications.
Keftab Dosing Protocols
| Condition | Adult Dose | Child Dose (≥1yr) | Duration |
|---|---|---|---|
| Skin infections | 500mg four times daily | 25-50mg/kg/day divided | 7-14 days |
| Uncomplicated UTI | 250mg four times daily | 12.5-25mg/kg/day divided | 7 days |
| Otitis media | Not typically used | 75-100mg/kg/day divided | 10 days |
Maintaining consistent dosing intervals is essential for Keftab's effectiveness. Doses should be spaced every six hours exactly, as exceeding eight-hour intervals significantly reduces antibiotic efficacy against common pathogens. The full course must be completed even if symptoms improve earlier to prevent bacterial resistance.
Keftab Dosing for Special Populations
Dosage Modification Guide
- Kidney impairment:
Creatinine Clearance (mL/min) Dosing Adjustment 10-50 Increase interval to 12-hour dosing Under 10 250-500mg every 24 hours - Liver impairment: Typically requires no dosage changes since Keftab isn't primarily metabolized by the liver
- Elderly patients: Initiate treatment at 50% standard dose if kidney function testing hasn't been performed
Older patients require careful monitoring - insufficient renal adjustment can lead to neurological side effects including muscle twitching and confusion. Always assess kidney function before initiating treatment in elderly populations.
Keftab Medication Safety Profiles
Absolute Contraindications
- Documented severe allergic reaction to cephalosporins like anaphylaxis
- History of cephalosporin-induced hemolytic anemia
- Previous toxic epidermal necrolysis reaction to any antibiotic
High-Risk Precaution Guide
| Medical Condition | Monitoring Requirement |
|---|---|
| Kidney impairment | Weekly creatinine level checks |
| History of colitis | Daily symptom tracking including stool frequency and consistency |
| Seizure disorders | Regular assessment for new neurological symptoms |
Patients with penicillin allergies require cautious use of Keftab. Current TGA guidelines indicate cross-reactivity occurs in under 10% of cases, but careful monitoring during initial doses remains essential.
Keftab Adverse Effects Management
Side Effect Response Protocol
- Common reactions (occurring in more than 10%):
- Antibiotic-associated diarrhea: Consider probiotic supplementation
- Vaginal yeast infections: Concurrent antifungal treatment may be required - Serious reactions (under 1% incidence):
- Pseudomembranous colitis: Requires immediate discontinuation
- Serum sickness-like reactions: Characterized by joint pain and fever
Preventative Measures
Consuming probiotic-rich foods like yoghurt may help maintain gut flora balance during treatment. Taking doses with food reduces nausea in susceptible individuals. Never stop Keftab treatment prematurely without consulting your healthcare provider, even if feeling better, to prevent recurrence and antibiotic resistance.
