Keftab (Cephalexin) Buyer and Patient Handbook in Singapore
What is Keftab?
Keftab is a cephalexin-based antibiotic available as oral pills that belongs to the β-lactam class. It is used to treat bacterial infections such as skin-and-soft-tissue infections, Ear Infections, Throat Infections, and urinary-tract infections. The product is approved by the Health Sciences Authority (HSA) in Singapore and supplied in strengths of 125 mg, 250 mg, 375 mg, 500 mg and 750 mg.
Who Should Use Keftab?
- Adults and adolescents (≥12 years) with confirmed bacterial infections
- Patients requiring a short-course oral antibiotic for outpatient treatment
- Individuals without a known allergy to penicillins or cephalosporins
How Does It Work?
Cephalexin interferes with bacterial cell-wall synthesis by binding to penicillin-binding proteins, which prevents the wall from forming properly and leads to bacterial death. Think of it as disabling the scaffolding a building needs to stay upright; the bacteria cannot survive without a sturdy wall. The medication has a low potential for abuse and is not habit-forming.
Why Choose Keftab?
- Brand consistency: Keftab is manufactured under strict GMP standards, ensuring each tablet delivers the exact declared dose.
- Convenient dosing: Multiple strengths allow clinicians to tailor therapy without high-dose tablets.
- Cost-effective alternative: Generic cephalexin tablets are widely available and provide the same clinical benefit at a lower price point.

- Children (<12 years): Use paediatric-specific formulations; Keftab tablets are not recommended.
- Renal impairment: Adjust dose according to creatinine clearance; consult a healthcare professional.

- No restriction on dairy, but large amounts of calcium may slightly lower drug levels; spacing intake by at least 2 hours is prudent.
- Grapefruit juice does not significantly affect cephalexin, but maintaining a balanced diet supports recovery.

Frequently Asked Questions
How long does a typical Keftab course last?
Usually 7-10 days, but the exact duration depends on the infection type and clinical response.
Can I drink alcohol while taking Keftab?
Moderate alcohol intake does not interfere with cephalexin, but avoid excessive drinking that may worsen stomach upset.
Is Keftab safe for people with mild kidney problems?
Yes, but the dose may need reduction; discuss with a healthcare professional.
Will Keftab protect me from future infections?
No. It treats the current Bacterial Infection but does not provide immunity.
What should I do if I develop a rash?
Stop the medication and contact a clinician promptly to assess for an allergic reaction.
Can I take Keftab with my other prescribed medicines?
Most drugs are compatible, but antacids, oral contraceptives, and anticoagulants require timing adjustments-see the interaction table.
Does Keftab work for viral infections like COVID-19?
No. Cephalexin targets bacteria; it has no effect on viruses.
How quickly will I feel better after starting Keftab?
Symptoms often improve within 48-72 hours, but complete eradication of the infection may take the full course.

Reviews
Got the 500mg capsules for a nasty UTI. Clearance was fast, maybe three days started to feel normal again. Biggest issue, and the thing everyone mentions, is the stomach churning. Seriously felt acid reflux all the time. **Pro Tip:** Eating a full, heavy meal right before taking it, not just a snack, minimizes the nausea. Still got the metallic taste though.
First time on Keftab 250mg for a stubborn skin infection. I expected tiredness but didn't expect the intense brain fog. Felt like I was walking through water mentally. Almost missed a deadline at work. Have to force myself to drink a literal gallon of water daily just to feel semi-functional. It's clearing the infection, which is great, but waiting for this three-day course to end.
Started Keftab six months ago for recurring folliculitis. It’s effective, hands down. My skin is clearer than it has been in years. The long-term compromise? Yeast infections. They hit every single time within a week of starting a new cycle. I now pre-load with heavy-duty acidophilus 5 days before starting the Keftab and continue for 7 days after I finish. It's exhausting, but necessary.
Had Keftab 750mg twice daily for ten days. Zero gastro issues, which was a huge relief, but the joint pain was intense. Specific hack: If you are getting muscle cramps or deep bone aches (especially at night), supplementing with magnesium glycinate an hour before your evening dose helps tremendously. It mellowed out the ache enough for me to actually sleep.
I’ve been cycling Keftab 500mg for ear infections for years. Works like a charm every single time, usually within 48 hours the pressure is gone. HOWEVER, I cannot drink coffee or anything acidic (like orange juice) within two hours of taking this pill. It makes the accompanying heartburn unbearable. Stick to plain water and fiber-rich foods while on this stuff.
Took this for a tooth abscess, 375mg three times a day. Worked fast, swelling went down immediately. Side effect profile was rough, though. Constant lightheadedness, like being slightly drunk all day. My pharmacist suggested splitting the dosage time to 8-hour intervals instead of the standard 6-hour interval to keep the blood levels steadier. That definitely reduced the dizziness.
I was prescribed Keftab for MRSA screening clearance and it did the job, screening came back negative. But it completely wrecked my IBS symptoms. My gut felt raw and painful for a week after even stopping the pills. For simple URIs, I can handle it. For anything long-term, the gastro consequences are too severe. Always keep high-quality probiotics in the freezer for this antibiotic.
It gets rid of the infection (sinusitis, in my case). It does that job well. But the fatigue is crushing. I mean, total collapse fatigue by 4 PM. Tried taking the morning dose early but it didn't help. What ended up working was taking B12 supplements in the morning. Didn't eliminate the tiredness, but it brought me up from zero energy to maybe 30%. Better than nothing.
