Phenimyxin ^*

Phenimixin is an antibiotic eye drop formulation that contains two complementary active ingredients: chloramphenicol and polymyxin B. Chloramphenicol is a broad-spectrum antibiotic effective against a wide range of Gram-positive and Gram-negative bacteria, while polymyxin B is particularly active against Gram-negative organisms. Together, they enhance antibacterial coverage and help reduce the risk of treatment failure in superficial ocular infections. Phenimixin is commonly prescribed for conditions such as bacterial conjunctivitis, blepharitis, and other external eye infections caused by susceptible organisms. The drops are applied directly to the affected eye(s), allowing the medication to act locally with minimal systemic absorption. As with all ophthalmic antibiotics, Phenimixin should be used exactly as directed by a healthcare professional to ensure effectiveness and to minimize the risk of resistance or adverse effects.
