Cetil 500 mg (Cefuroxime)
Cetil 500 mg contains cefuroxime, a second-generation cephalosporin antibiotic used to treat a broad range of bacterial infections including respiratory tract infections, ENT infections, skin and soft tissue infections, and urinary tract infections. Cefuroxime works by inhibiting bacterial cell wall synthesis, leading to bacterial death and clinical improvement when used appropriately.
The 500 mg formulation provides robust systemic coverage for moderate to severe outpatient infections and is commonly prescribed when higher oral dosing is needed.
Product introduction
Cefuroxime is effective against many Gram-positive and selected Gram-negative organisms. It is often chosen for respiratory and ENT infections (sinusitis, otitis media), skin infections, and some urinary infections. Cetil 500 mg is formulated for oral administration and may be used where a stronger oral cephalosporin is required.
As with all antibiotics, use only when prescribed by a healthcare professional and follow antimicrobial stewardship guidance to limit resistance.
Uses of Cetil 500 mg (Cefuroxime)
Cetil 500 mg is indicated for bacterial infections including:
- Respiratory tract infections: bronchitis, sinusitis, and selected cases of pneumonia
- ENT infections: otitis media, tonsillitis, sinusitis
- Skin & soft tissue infections: cellulitis, wound infections
- Urinary tract infections (UTIs): uncomplicated and some complicated UTIs guided by sensitivity
- Bone & joint infections (specialist-guided therapy)
- Post-dental infection and prophylaxis in some dental procedures (clinician-guided)
Note: Cefuroxime is not effective against viral illnesses (e.g., common cold, flu).
Benefits of Cetil 500 mg (Cefuroxime)
Benefits include:
- Broad activity including many Gram-positive cocci and Gram-negative rods.
- Reliable oral therapy for a variety of community infections.
- Good tolerability in most patients.

In Treatment of Worm infections
Important: Cefuroxime is not an antiparasitic or anthelmintic. This section is included to follow your format — use targeted antiparasitic agents for worm infections. Cefuroxime may be used if there is a bacterial co-infection.
Side effects of Cetil 500 mg (Cefuroxime)
Most side effects are mild and self-limited, but serious reactions can occur rarely.

How to use Cetil 500 mg (Cefuroxime)
- Take exactly as prescribed by your clinician.
- Typical adult oral dose often is 250–500 mg twice daily depending on infection severity—follow the prescribed regimen.
- May be taken with or without food; taking with food reduces stomach upset.

If symptoms worsen or do not improve within 48–72 hours, contact your healthcare provider.
How Cetil 500 mg (Cefuroxime) works
Cefuroxime binds to penicillin-binding proteins (PBPs) in susceptible bacteria, blocking peptidoglycan cross-linking in the cell wall. This weakens the bacterial cell wall and leads to cell lysis and death — a bactericidal action most effective against actively dividing bacteria.
Safety advice
| Allergies | Avoid if allergic to cephalosporins; exercise caution in patients with severe penicillin allergy. |
| Pregnancy | Generally considered safe when prescribed by a clinician; discuss with your obstetrician. |
| Breastfeeding | Small amounts pass into breastmilk — discuss risks and benefits with your clinician. |
| Kidney disease | Dose adjustment may be required in renal impairment. |
| Alcohol | No specific interaction but avoid heavy drinking while unwell. |
| Drug interactions | May interact with oral contraceptives, anticoagulants and some other drugs — check with your pharmacist. |
What if you forget to take Cetil 500 mg?
If you miss a dose, take it as soon as you remember. If it’s nearly time for your next dose, skip the missed dose. Do not double the dose.
