Indicated for: eye or ear infections with inflammation
Route of administration: ophthalmic
Substance: chloramphenicol + betamethasone (antibacterial antibiotic + glucocorticoid)
ATC: S01CA05 (Sensory organs | Antiinflammatory agents and antiinfectives in combination | Corticosteroids and antiinfectives in combination)
Chloramphenicol and betamethasone are used in combination in certain medications to treat bacterial infections associated with inflammation. This combination is commonly found in topical products (ointments, creams, or eye/ear drops) and is indicated for conditions such as bacterial conjunctivitis, blepharitis, otitis externa, or other inflammatory skin infections.
Chloramphenicol is a broad-spectrum antibiotic that inhibits bacterial protein synthesis, making it effective against a wide range of gram-positive and gram-negative bacteria. Betamethasone is a corticosteroid with anti-inflammatory and anti-allergic properties, which reduces inflammation, swelling, and itching associated with infections.
While this combination is effective, its use requires caution. Chloramphenicol may cause rare side effects, such as hypersensitivity reactions or, in very rare cases, bone marrow aplasia (a serious bone marrow condition). Betamethasone, if used long-term or in large amounts, can lead to systemic side effects, such as suppression of the hypothalamic-pituitary-adrenal axis, skin thinning, or secondary infections.
This combination should be used as directed by a doctor, and the duration of treatment should be limited to reduce the risk of side effects. It is important to avoid long-term use or application over large areas of the skin. If severe side effects or persistent symptoms occur, immediate medical attention is necessary.
