The medication regimens of 243 children aged 1-16 years were analysed. The children were resident in five Districts in the Northern Region, England and were taking medication orally in liquid or syrup form for chronic disease. 39% of the children were under 5 years of age and 44% were aged 5-11 years, with slightly more males in most age groups. Epilepsy, chronic renal disease and cystic fibrosis were the most common medical problems for which the medicines were prescribed long-term. The duration of medication ranged between 3 months and 12 years; the average duration varied according to the disease and the type of medicine. Most of the anticonvulsants and vitamins had been used for 2 years or more, whereas most of the anti-asthmatic drugs were used for a period of up to a year only. Twenty six (39%) of the 67 different preparations used contained sugar, 19 (28%) were sugar-free, and the sweetening agent in the remainder varied according to how they were prescribed. Specificity of prescribing was the major determinant in the dispensing of either the sugar-containing or the sugar-free medicines.
