Since Norplant does not contain estrogen like other birth control pills, older women, women who smoke, and women with high blood pressure are not restricted from using this method.
Kwa kuwa Norplant haina estrojeni kama vile vidonge vingine vya kudhibiti uzazi, wanawake wazee, wanawake wanaovuta sigara na wanawake walio na shinikizo la damu hawazuiliwi kutumia njia hii.
