An evaluation of the available pharmacotherapy for the treatment of hirsutism.

INTRODUCTION: Hirsutism is the presence of excessive body hair in a male pattern distribution in a woman, and can affect up to 20% of women. It can be associated with high levels of psychosocial and psychosexual morbidity. It is a common cause for presentation to medical staff, particularly endocrinologists, gynecologists, and dermatologists. AREAS COVERED: The authors discuss the definition, causes, and diagnosis of hirsutism. Current and evolving pharmacotherapy is available for hirsutism with an evaluation of the available evidence, consensus opinions, and guidelines to date. Physical therapies that can be recommended in combination with medical pharmacotherapies are also outlined. EXPERT OPINION: Combined oral contraceptive pills (OCP) are recommended as first-line therapy. The addition of oral antiandrogens can be combined for severe cases. Antiandrogens and OCPs have been demonstrated to be the most effective pharmacotherapy available in improving hirsutism. Greater insight is being achieved in the use of antiandrogens and their role in managing hyperandrogenism states such as hirsutism. Insulin sensitizers such as metformin are found to be the least effective. Medical treatments for hirsutism often need to be combined with physical therapies for optimal management. Psychological support should be considered in patients with associated psychosocial morbidity.
