Cef-3 Capsule/Suspension: Uses, Dosage, Side Effects – 2026

Cef-3 is a potent third-generation cephalosporin antibiotic containing Cefixime. It is a bactericidal agent, meaning it kills bacteria by interfering with the synthesis of their cell walls. In Bangladesh, it is a flagship product of Square Pharmaceuticals PLC, highly regarded for its stability against many beta-lactamase enzymes that make other antibiotics (like penicillins) ineffective.

What is Cef-3 Used For?

Cef-3 is prescribed for a wide range of bacterial infections:

• Respiratory Tract Infections: Including bronchitis, pneumonia, sinusitis, and tonsillitis.

• Urinary Tract Infections (UTIs): Effective for both simple and complicated bladder or kidney infections.

• Ear & Throat Infections: Commonly used for acute otitis media (middle ear infection) and pharyngitis.

• Typhoid Fever: It is one of the primary oral treatments for enteric fever (typhoid) in the South Asian region.

• Gonorrhea: Used as a single-dose treatment for uncomplicated cervical or urethral gonococcal infections.

Clinical research confirms that Cefixime reaches effective concentrations in various body tissues quickly. For more, see this pharmacology study on Cefixime.

Dosage & Forms

Cef-3 comes in various strengths (200mg, 400mg, and pediatric suspensions).

• Adults (over 12 years): Usually 200 mg to 400 mg daily, taken either as a single dose or in two divided doses.

• Children (6 months to 12 years): Dosage is usually based on weight (8 mg/kg daily).

  • General guide: 1–4 years: 100 mg daily; 5–10 years: 200 mg daily.

• Typhoid Fever: The dose is often higher (10 mg/kg daily) and continued for 14 days.

• Administration: Can be taken with or without food. Taking it with a meal may help reduce potential stomach upset.

Key Reminder: Always finish the full course prescribed by your doctor. Stopping early—even if you feel better—can lead to antibiotic resistance.

• Diarrhea (most common, especially with higher doses)

Important Warnings & Precautions

• Kidney Disease: Patients with severe renal impairment require a dose adjustment.

• Alcohol: While no severe direct interaction exists, alcohol can increase dizziness and should be avoided during the course.

• Pregnancy & Breastfeeding: Generally considered safe (Category B), but should only be used if clearly needed and prescribed by a doctor.
