Welldorm tablets are used for the short-term treatment of severe insomnia (sleeping problems) which is
interfering with normal daily life.
Welldorm will normally be given in addition to other non drug therapies e.g. counselling. Welldorm is
normally used in adolescents under the supervision of a medical specialist.
