Clinical assessment of a low-dose oestrogen, low-dose progestogen combined oral contraceptive.

ABSTRACT

PIP The efficacy, safety, and patient acceptance of an oral contraceptive containing 150 mcg d-norgestrel and 30 mcg ethinyl estradiol (150/30) were studied in 99 women who completed 754 cycles of medication between late 1971 and October 1973. 1 pregnancy occurred giving a pregnancy rate of 1.6 per 100 woman-years. This woman's previous history indicated unreliability in pill taking. The mean pretreatment length of menses was 4.9 days and during treatment, 4 days. Although intermenstrual bleeding and amenorrhea were noted in early cycles, there was a decrease in the usual incidence of headaches, nausea, vomiting, and depression. Results of the study and patients' acceptance suggest that the 150/30 combination may be used as the oral contraceptive of first choice.^ieng
