Sanofi-Aventis would like to inform healthcare professionals of the risk of congenital malformations and serious developmental disorders in children exposed in utero to Epilim® (sodium valproate, valproic acid). Children exposed in utero to valproate are at a high risk of serious developmental disorders and/or congenital malformations. Hence, valproate should not be prescribed to female children, female adolescents, women of childbearing potential or pregnant women unless other treatments are ineffective or not tolerated. Valproate treatment must be started and supervised by a specialist experienced in managing epilepsy or bipolar disorder. Healthcare professionals are advised to carefully balance the benefits of valproate treatment against the risks when prescribing valproate for the first time, at routine treatment reviews, when a female child reaches puberty and when a woman plans a pregnancy or becomes pregnant. They are also advised to ensure that all female patients are informed of and understand the risks associated with valproate during pregnancy; the need for  effective contraception and regular treatment review as well as the need to rapidly consult her physician if she is planning a pregnancy or becomes pregnant. The local package inserts for Epilim® products have been strengthened on the warnings on valproate use in pregnancy.Please refer to the letter for more information.
