The Effect of Carnitine Supplementation on Blood Ammonia Level in Epilepsy Children Treated with Valproic Acid: A Randomized Controlled Trial

Background: Long-term use of valproic acid is associated with a high level of blood ammonia related to carnitine deficiency. This study investigates the effect of carnitine supplementation on blood ammonia levels in children with epilepsy who have been treated with valproic acid for more than six months.Materials and Methods: This was a randomized, double-blind, placebo-controlled trial study where children with epilepsy who were treated with valproic acid were randomly allocated to the carnitine supplementation and control group. All children were followed for month, and then measured for blood ammonia level. Blood ammonia levels of both groups were compared using an Independent t-test with a significant of p
