18-month progestogen-only contraception during breast-feeding in Libyan women

Abstract

This study was undertaken to evaluate the efficacy and the influence of progestogen-only contraceptives (POCs) in postpartum lactating mothers over a period of 18-months. 250 mothers were randomised to either the study groups or the control group. In the study groups, 100 mothers were given an oral progestogen pill; lynestrenol and another 100 mothers were assigned to injectable progestogens; depot medroxy-progesterone acetate (DMPA) and norethisterone oenanthate (NET EN), 50 each.The control group (n=50) was given nonhormonal methods.There was no contraceptive failure or negative influence on lactation among the medication groups.There were no significant differences between the groups with respect to the continuation rates and to the adverse effects that led to premature discontinuation. In conclusion, POCs can be used by lactating mothers effectively and safely for at least 18 months.Therefore, the wide use of these methods should be recommended if the international targets to protect, promote and support breast-feeding as well as family planning are to be achieved
