Managing sore throat: a literature review. II. Do antibiotics confer benefit?

OBJECTIVE

To assess the justification for the use of antibiotics in the management of sore throat in general practice.

DATA SOURCES

The literature from 1945 to 1990 was systematically screened to identify studies that addressed the question whether antibiotics reduce non-suppurative and suppurative complications and symptoms of sore throat. The key-words, "pharyngitis" and "tonsillitis" were used to identify trials of antibiotics for the treatment of sore throat.

STUDY SELECTION

Studies were included in comparison tables if they involved the trial of one or more antibiotics against a control and there was an outcome in terms of reduction in the incidence of acute rheumatic fever, acute glomerulonephritis, acute otitis media, acute sinusitis, quinsy or any symptoms related to the acute illness.

RESULTS

The published literature suggests that antibiotic treatment protects patients with sore throat against acute rheumatic fever and some suppurative complications, but not against acute glomerulonephritis. It does not reduce the symptoms.

CONCLUSIONS

In Australia, with the exception of socioeconomically deprived Aboriginal communities, the incidence of acute rheumatic fever is probably not high enough to justify the use of antibiotics for sore throat. Protection against suppurative infection seems to be slight and it is difficult to establish the benefit of antibiotic treatment for reducing the symptoms of sore throat. Until more benefits for antibiotic management of sore throat can be demonstrated, it is recommended that infrequent use be adopted.
