Description
Cefaclor, the key component in this 250mg syrup/suspension, belongs to the second-generation cephalosporin antibiotics. It achieves its bactericidal action by interfering with bacterial cell wall synthesis, specifically by attaching to penicillin-binding proteins (PBPs) in vulnerable bacteria. This prevents the cross-linking of peptidoglycan chains, compromising the cell wall’s strength and resulting in bacterial lysis and elimination. The effect targets bacteria exclusively, as human cells lack cell walls and remain unaffected.

- Inform providers of use before lab tests, as it may interfere.
- Store securely away from children and pets at room temperature.
Drug Interactions
- Probenecid may elevate cefaclor levels by slowing excretion.
- Combined with nephrotoxic agents (e.g., aminoglycosides, diuretics) could raise kidney damage risk.
- May lessen oral contraceptive efficacy; use backup methods.
- Can cause false positives in urine galactose tests.
- Antacids with aluminum, magnesium, or calcium might hinder absorption.
- Could impact live bacterial vaccines like typhoid.
- Monitor prothrombin time with anticoagulants such as warfarin.
Food Interactions
- Can be taken regardless of meals, though food may ease stomach issues.
- Steer clear of alcohol to avoid amplified side effects or reduced efficacy.
- High-fat foods might slow absorption.
- Grapefruit products: Use cautiously, though no confirmed interaction.
