Further study on the effect of norethisterone enanthate, an injectable contraceptive on body functions

One hundred and fortythree healthy Bengali women have received norethisterone enanthate, as injectable contraceptive in doses of 200 mg. intramuscularly at intervals of 10 to 12 weeks. The drug have been found to be almost 100 percent effective in the control of fertility. Menstrual disturbance, e.g. amenorrhoea, irregular bleeding and spotting, appeared to be the main complaints of the clients during the initial period of the therapy; but these did not persist long. There was no ill effect of the drug on lactation. No significant change in body weight, blood pressure, platelet count, fasting blood sugar, serum cholesterol and total plasma protein level was observed following administration of norethisterone enanthate over one year.
