Health Update: Blue cycle

WOMEN on antidepressants may need higher doses just before their periods. Doctors at the Cleveland Clinic Foundation in Ohio report two cases where blood concentrations of antidepressant halved before menstruation; both women had said their symptoms became worse in the premenstrual period. Increasing the dose seven to 10 days before a period improved symptoms, says a report in the Journal of Psychosomatic Obstetrics and Gynaecology.
