Ceftibuten is an oral third-generation cephalosporin used for select pediatric respiratory and urinary infections when susceptible organisms are confirmed.
Once-daily dosing supports adherence but requires empty-stomach administration for suspension.
Not effective against many gram-positive organisms; combine or choose alternatives when strep coverage is required.
Monitor for beta-lactam cross-reactivity in patients with penicillin allergy.
Adjust dosing in moderate to severe renal impairment.
Watch for antibiotic-associated diarrhea including C. difficile infection.
Ceftibuten is an oral cephalosporin with enhanced activity against beta-lactamase–producing respiratory pathogens. Use it intentionally after first-line therapy fails or cannot be tolerated.
Ideal for otitis media, sinusitis, and gram-negative infections requiring once-daily dosing when adherence is a concern.
| Condition | Age Range | First Line? | Notes |
|---|---|---|---|
| Acute otitis media | Children ≥6 months | No | 9 mg/kg/day divided BID for 10 days may be considered when high-dose amoxicillin or amoxicillin-clavulanate cannot be used and culture suggests susceptible gram-negative pathogens. |
| Acute bacterial rhinosinusitis | Children and adolescents | No | Reserve for penicillin-intolerant patients when local resistance patterns allow and beta-lactamase production is likely. |
| Uncomplicated urinary tract infection | Children and adolescents | No | Use culture-directed therapy when Enterobacterales are susceptible and first-line agents (nitrofurantoin, TMP-SMX) are unsuitable. |
| Exacerbations of chronic bronchitis in cystic fibrosis | Adolescents | No | Used selectively under pulmonology supervision when gram-negative organisms are susceptible. |

Ceftibuten is generally well tolerated; mild GI symptoms are most common.
Serious hypersensitivity and C. difficile-associated diarrhea are rare but important counseling points.

Common concerns and practical guidance
Ceftibuten’s once-daily suspension simplifies dosing, but the empty-stomach requirement is crucial for therapeutic levels.
Shake the suspension vigorously for at least 15 seconds. Give at least 2 hours before or 1 hour after a meal. Capsules can be taken with or without food but take consistently the same way.
Store reconstituted suspension in the refrigerator and discard after 14 days. Use a dosing syringe for accuracy.
Emergency contact: Seek urgent care for difficulty breathing, swelling of the face, severe rash, or persistent bloody diarrhea.
Complete the entire course even if symptoms improve within a few days.

Expert pearls and evidence-based tips
Ceftibuten is a third-generation oral cephalosporin designed to target gram-negative respiratory pathogens with high beta-lactamase stability.
The active ceftibuten molecule binds penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking and producing bactericidal cell wall damage. Like other beta-lactams, its efficacy is time-dependent: maintaining plasma concentrations above the pathogen MIC for at least 40% of the dosing interval optimizes killing.

Understanding your child's medication is important. We've created comprehensive guides to help you safely administer Ceftibuten and monitor your child's response to treatment.
Food reduces absorption. Give 2 hours before or 1 hour after meals for best results.
Keep refrigerated and discard after 14 days.
Yes. Separate by at least 2 hours to avoid binding the antibiotic.
Give it as soon as remembered unless it is close to the next dose. Do not double up.
