The safety of Sino-implant (II) for women with medical conditions or other characteristics: a systematic review

[Hypertension and contraception]

Hypertension is a major risk factor for cardiovascular diseases. Because of the high frequency of hormonal contraceptives use, assessing their side effects is an important public health issue. In this perspective, we conducted a review of the risk of hypertension associated with the use of hormonal contraceptives, either combined estrogen-progestin or only progestin. The use of combined hormonal contraceptives, regardless of its type and route of administration, is associated with a slight increase in blood pressure, both systolic and diastolic blood pressures. The frequency of onset of hypertension in women who use combined hormonal contraception is between 0.6% and 8.5%. Progestin-only contraception seems safe with respect to the risk of hypertension. It is therefore important to remember that the use of combined hormonal contraception is contra-indicated in hypertensive women, even well controlled. Finally, we propose a prescription assistance algorithm according to the recommendations of an expert panel. It should be remembered that taking blood pressure at each contraceptive consultation (initial and follow-up) is essential.
