EDITORIAL COMMENT: Prostaglandin synthetase inhibitors, antifibrinolytic agents, oral contraceptives and the release of progestogen from a levonorgestrel-releasing intrauterine contraceptive device (IUD) have all been shown to be effective in the treatment of idiopathic menorrhagia; a recent study found the progestogen-releasing IUD to be the most effective of these methods1 We accepted this case report to inform readers that severe anaemia from pubertal menorrhagia due to a haemorrhagic disorder can be successfully treated with oral contraceptive tablets. This is a message to be remembered for the rare patient with life-threatening menorrhagia and a coagulation disorder whose general medical condition may preclude surgery - the simple contraceptive pill may control the problem.
