Although conjuncitivitis outside of the neonatal period is commonly caused by viruses, there are times when antibiotics are warranted due to bacterial infections, such as conjuncitivits-otitis syndrome.
- up to 25% of patients with conjunctivitis have concurrent otitis media (even in the abscence of ear pain) and up to 73% of patients with purulent conjunctivitis
- Non-typeable H. influenzae is the most common recovered bacteria.
- For these patients, systemic (oral) antibiotics are recommended and the topical ophthalmic antibiotics are NOT necessary.
- Antibiotics should cover beta-lactamase producing organisms, e.g. high dose amoxicillin-clavulanic acid (45 mg/kg BID; 600 mg/5mL concentration which is formulated to have less clavulanic acid
Bottom line: Every patient with conjunctivitis should have an examination of his/her TMs, as your management may change.
