Contraceptive Pearl: Hormonal Contraceptives and Smoking

About one-quarter of American women smoke cigarettes. Can smokers safely use hormonal contraceptives?

Smokers who use estrogen-containing contraceptives (the pill, patch and vaginal ring) raise their risk for deep vein thrombosis, coronary heart disease, and stroke. This risk increases with age. Risk increases further for women with multiple cardiovascular risk factors (such as hypertension, hyperlipidemia, and diabetes mellitus).

How do we gauge this risk? The World Health Organization has sifted through the data and created guidelines on eligibility for contraception. Because women under age 35 have a low baseline risk for cardiovascular disease, they may take estrogen-containing contraceptives with a mild caution, no matter how much they smoke. Those over age 35 who smoke fewer than 15 cigarettes per day may use estrogen-containing contraceptives with a stronger caution. Women over age 35 who smoke more than 15 cigarettes a day shouldn’t take estrogen.

Women who can’t take estrogen-containing contraceptives should consider an IUD (copper or progestin), progestin implant, progestin injection, and barrier methods.
