Multiple prescriptions of antibiotics for children aged 0 to 5 years in relation to type of antibiotic.

The risk of receiving more than one prescription within an antibiotic course was examined for all children aged 0 to 5 years in a Danish county during 1997. We identified 29,307 prescriptions of systemic antibiotics for 16,245 children in a prescription database. Ten per cent of the prescriptions were followed by a new prescription within 10 days. In children who received two prescriptions (n = 3993), 19% redeemed the prescriptions within the same course. When the child was prescribed penicillin V, compared with broad-spectrum penicillin, the odds ratio of receiving a repeat prescription within 1-2 days was 2.9 (95% CI 2.5-3.4) and within 3-10 days 1.3 (95% CI 1.2-1.5).
