Use of an oral contraceptive containing drospirenone in an extended regimen.

As well as providing reliable contraception, modern low-dose oral contraceptives may offer some non-contraceptive advantages. Positive effects on problems such as edema with weight increase and breast tenderness, bloating, dysmenorrhea, and an improvement in skin and hair condition have been reported in several studies using an oral contraceptive containing drospirenone. If these disorders are cycle-dependent, use of the contraceptive in an extended regimen may be of additional benefit. The study reported in this paper followed 1433 women, 175 of whom took the drospirenone-containing pill continuously for between 42 and 126 days. Some symptoms of the premenstrual syndrome were influenced very satisfactorily by administration in an extended regimen.
