Velosef 500 mg (Cephradine) — Uses, Dosage Pakistan
- Velosef = cephradine, a first-generation cephalosporin
- Used for skin, throat, and UTI bacterial infections
- Standard dose: 500 mg twice daily, 7–10 day course
- Cross-reactivity risk with penicillin allergy (10%)
- Always complete the full course — prevents antibiotic resistance
What Is Velosef 500?
Velosef is Pfizer's brand name for cephradine — a first-generation cephalosporin antibiotic effective against a broad range of bacteria. It is one of the most commonly prescribed antibiotics in Pakistan.
| Generic name | Cephradine |
| Class | First-generation Cephalosporin |
| Available forms | 250 mg & 500 mg capsules; syrup 125 mg/5 ml and 250 mg/5 ml; injection (hospital/clinic use) |
| OTC | Prescription only |
| Pakistan price | ~250–400 PKR for 12 capsules |
Velosef Forms — Capsule, Syrup and Injection
Velosef is widely assumed to be a 500 mg capsule only, but it is marketed in Pakistan in three different forms. The form is chosen by your doctor, based on age, ability to swallow and how severe the infection is. Here is what each one is:
| Form | Strength | Typically for |
|---|---|---|
| Velosef capsule | 250 mg | Milder infections, and where a smaller dose is appropriate |
| Velosef capsule | 500 mg | The most common adult form — skin, throat and urinary infections |
| Velosef syrup | 125 mg/5 ml | Young children — dose calculated by body weight |
| Velosef syrup | 250 mg/5 ml | The same syrup, more concentrated, so a smaller volume is given |
| Velosef injection | Varies by brand | In hospital or clinic, when the patient cannot take medicine by mouth |
The two syrup strengths are not interchangeable. 5 ml of the 250 mg/5 ml syrup contains as much medicine as 10 ml of the 125 mg/5 ml syrup — so repeating a previous dose without checking the label can be wrong. Read the strength on the bottle every time, and shake it well before pouring.
A child's syrup dose is always based on weight, not age — do not calculate it yourself. Ask your doctor or pharmacist for the exact millilitre amount. (Paediatric dosing is covered in the Dosage section below.)
Never self-administer the injection. Velosef injection is given only by a healthcare professional — usually when vomiting prevents a patient keeping capsules down, or when the infection is severe. Once the patient improves, doctors commonly switch back to capsules or syrup to complete the course.

Dosage
| Group | Dose |
| Adults | 500 mg twice daily (mild) or 4 times daily (moderate–severe) |
| UTI | 500 mg twice daily for 7 days |
| Skin/throat infection | 500 mg twice daily for 7–10 days |
| Children (1+ year) | 25–50 mg/kg/day in divided doses |
| Best time | On an empty stomach or with food — both acceptable |
Specific Conditions:
- Strep throat: 10-day course (prevents rheumatic fever)
- Cystitis: 7 days
- Skin infection: 7–14 days
- Sinusitis: 10 days
Always Complete the Full Course!
Pakistan faces a serious antibiotic resistance crisis. Stopping Velosef when symptoms improve after 3–4 days:
- Allows bacteria to develop resistance
- Makes antibiotics less effective for future infections
- Can cause the infection to return in a stronger form
- With strep throat, raises the risk of rheumatic heart disease
Penicillin Allergy and Velosef
Important: Cephalosporins (including Velosef) and penicillins share a similar chemical structure. Cross-reactivity occurs in 5–10% of penicillin-allergic patients:
- Mild penicillin allergy (rash only) — Velosef can be used with caution
- Severe penicillin allergy (anaphylaxis) — Velosef is completely contraindicated
- Always tell your doctor about any allergy history
Side Effects
Common:
- Loose stools / diarrhoea
- Nausea, vomiting
- Stomach pain
- Mild rash
- Vaginal yeast infection (in women)
Serious (Rare):
- Severe allergic reaction (anaphylaxis)
- C. difficile colitis (severe diarrhoea after antibiotics)
- Stevens-Johnson syndrome
- Liver problems
- Blood disorders (reduced white cell count)
- Kidney issues

Velosef vs Augmentin
| Velosef | Augmentin 625 |
| Cephalosporin | Amoxicillin + clavulanic acid |
| Good for skin, throat, UTI | Broader spectrum coverage |
| Caution with penicillin allergy | Penicillin family — avoid if allergic |
| Generally less expensive | Slightly more expensive |
| Less stomach upset | More diarrhoea |
Take a Probiotic Alongside
Velosef disrupts gut bacteria. Take a probiotic (yoghurt, Enterogermina, Bifilac) with a 2-hour gap from each dose to protect your gut flora.
Pregnancy and Breastfeeding
- Pregnancy: Generally safe (Category B). Commonly used for UTIs in pregnancy.
- Breastfeeding: Safe — only a small amount passes to the baby. Baby may develop mild loose stools.
Drug Interactions
- Probenecid: Increases cephradine levels
- Other nephrotoxic drugs: Increased kidney damage risk
- Combined oral contraceptives: Slightly reduced effectiveness — use backup contraception
- Alcohol: Mild interaction, generally acceptable
- Anticoagulants (Warfarin): Slight increase in bleeding risk
Special Populations
Kidney Disease:
Dose adjustment is required. Dialysis patients need special dosing schedules.
Elderly Patients:
Dose adjustment may be needed due to declining renal function.
Children:
Velosef syrup is safe — dose calculated by weight. Recommended from 1 year of age.
Antibiotic Resistance — A National Crisis
Antibiotic overuse in Pakistan has already produced serious consequences — XDR (extensively drug-resistant) typhoid, MRSA, and multidrug-resistant TB. Velosef is also gradually becoming resistant in certain bacteria. Responsible use is everyone's responsibility.
Common Misuse in Pakistan
- Buying from pharmacy without a prescription
- Taking for colds and flu (viral) — completely ineffective
- Stopping the course midway
- Giving leftover medicine to another child
- Changing the doctor's prescribed dose
- Saving leftover antibiotics for future use
Brands in Pakistan
- Velosef (Pfizer/BMS)
- Sefradine
- Veidot
- Generic cephradine options
Conclusion
Velosef 500 is a commonly prescribed first-generation cephalosporin in Pakistan that is effective for skin, throat, UTI, and respiratory bacterial infections. Always get a prescription, complete the full course, and disclose any penicillin allergy history. Take a probiotic alongside to protect your gut.

Frequently Asked Questions
What conditions is Velosef 500 used for?
Velosef 500 (cephradine) is a first-generation cephalosporin antibiotic used for bacterial infections including: skin infections (cellulitis, boils, wounds), respiratory infections (strep throat, tonsillitis, sinusitis, bronchitis), UTI (cystitis, kidney infection), ear infections (otitis media), and bone/joint infections. Only effective against bacterial infections — no effect on viral illnesses. Prescription required.
What is the dosage for Velosef 500?
For adults: 500 mg twice daily (mild infections) or four times daily (moderate to severe). UTI: 500 mg twice daily for 7 days. Strep throat: 500 mg twice daily for 10 days. Skin infection: 500 mg twice daily for 7–14 days. For children: 25–50 mg/kg/day in divided doses. Always complete the full course — even when symptoms improve.
Is Velosef safe with a penicillin allergy?
Use with caution. Cephalosporins and penicillins share a similar structure — there is a 5–10% cross-reactivity rate. With a mild penicillin allergy (rash only), Velosef can be used under careful monitoring. With a severe penicillin allergy (anaphylaxis), Velosef is completely contraindicated. Always tell your doctor about any allergy history. Alternatives: macrolides (azithromycin), fluoroquinolones.
What are the side effects of Velosef?
Common: loose stools, nausea, vomiting, stomach pain, mild rash, vaginal yeast infection in women. Serious (rare): severe allergic reaction (anaphylaxis), C. difficile colitis (severe diarrhoea after antibiotics), Stevens-Johnson syndrome, liver problems. Take a probiotic (yoghurt, Enterogermina) with a 2-hour gap to protect gut bacteria. See a doctor if side effects worsen.
What is the difference between Velosef syrup and capsules?
Both contain the same medicine, cephradine — the difference is the form and the concentration. Capsules (250 mg and 500 mg) are for adults and older children who can swallow them; the syrup is for young children and comes in two strengths, 125 mg/5 ml and 250 mg/5 ml. The two syrups are not interchangeable — 5 ml of the 250 mg/5 ml syrup contains as much medicine as 10 ml of the 125 mg/5 ml one. A child's dose is based on body weight, not age, so never calculate it yourself: give only the millilitre amount your doctor specified, and check the strength printed on the bottle every time.
When is Velosef given as an injection?
The injectable form is used when medicine by mouth is not possible or not sufficient — for example with severe vomiting, in an unconscious patient, or when a serious infection is being treated in hospital. It is given only by a healthcare professional in a hospital or clinic and should never be administered at home. As the patient improves, doctors usually stop the injection and switch to capsules or syrup so the course can be completed.
Is Velosef safe in pregnancy and breastfeeding?
Yes, Velosef is generally safe in pregnancy (FDA Category B) — it is commonly used for UTIs and skin infections during pregnancy. It is also safe during breastfeeding — only a small amount passes to the baby. The baby may develop mild loose stools, but this is not harmful. Do not start without a doctor's advice. Always mention any penicillin allergy history.
