Objective To determine contraceptive efficacy and safety of
the long term administration of the low dose oral monophasic contraceptive
containing 0,02 mg ethinylestradiol/2mg chlormandione acetate.

menses, who have signed inform consent. Exclusion criteria: smokers over 35
years, BMI over 30, irregular menses, PCOS, abnormal cervical cytology, aberrant
coagulation patterns, abnormal liver tests, failure to comply with pills
administration schedule. Patients had to fill a diary recording symptoms as:
headache, breast tension, nervousness, libido status, nausea, vomiting and
bleeding pattern. Any adverse event was noted down and analyzed concerning
relation to drug administration.
Results From 80 patients who matched the
inclusion criteria, 67 finished the study. There was no pregnancy during the
study, except one case who failed to take investigational product according to
schedule. There was no major abnormal bleeding pattern, spotting being the major
symptom in 21 cases, and 7 cases of irregular bleeding in the first 3 months
