[Right treatment of red eyes - prescription of topical antibiotics for infectious conjunctivitis is still common in Sweden].

Conjunctivitis is one of the most common ophthalmologic conditions in general medical practice. In most cases, it is self-limiting and do not require topical antibiotic therapy. In a retrospective, observational cohort study during 2013-2017 in a region in Sweden conjunctivitis was diagnosed in 32 000 cases in primary care. Antibiotics were prescribed in 66% of undefined and in 83% of purulent conjunctivitis. Fusidic acid was the most common medication with 81% followed by chloramphenicol with 17%. Although unnecessary, the treatment is probably harmless. Toxicity is uncommon and the cost is low. Increased consciousness of this issue may however decrease resistance to antibiotics and support evidence-based medical practice.
