A new oral contraceptive based on the normophasic method.

62 women were treated for 554 cycles with normophasic oral contraceptive Fisioquens. A treatment cycle consists of 7 tablets of 0.05 mg ethinyloestradiol, followed by 15 tablets with a combination of 0.05 mg ethinyl-oestradiol and 1 mg lynestrenol. No pregnancies occurred. Both tolerance of the preparation and cycle control were good. Irregular bleeding occurred sporadically. Various side-effects diminished during treatment and even disappeared completely. Fisioquens appears to be a reliable contraceptive with a minimum of side-effects.
