Medication cost reduction in children on the ketogenic diet: data from a prospective study.

In a prospective study of the efficacy of the ketogenic diet in children with severe, refractory epilepsy, data were collected on medication changes over 1 year. Cost reductions in medications were calculated over the first year and estimated for a second year. Fifty-seven percent of the children stayed on the diet for 1 year, and 74% of these children had their number of medications reduced. Forty-eight percent of children who stayed on the diet were on no medications at 12 months follow-up. Daily medication costs were reduced by nearly 70%.
