The relationship between smoking and hormone replacement therapy (HRT) is complex. There are valid concerns that smoking may increase the health risks of taking HRT, but stopping smoking is not an absolute requirement for HRT eligibility. The decision to initiate or continue HRT in smokers should be made carefully on an individual basis, weighing the benefits and potential risks.
Several studies have shown an increased risk of cardiovascular disease, including stroke and heart attack, in women who smoke and use HRT, especially those on estrogen-only therapy. Smoking combined with HRT also appears to increase the risk of blood clots. The mechanisms are not fully understood, but likely involve changes in clotting factors and vascular inflammation caused by smoking and interaction with exogenous hormones.
However, it's not clear if these risks are high enough to contraindicate HRT altogether for smokers. Much depends on the woman's age, whether she has reached menopause, severity of menopausal symptoms, and her personal risk factors. A good principle is that the shorter duration of HRT the better in smokers to limit long-term risks.
For younger women taking HRT to treat premature ovarian insufficiency or primary ovarian failure, the benefits may outweigh the risks even if smoking continues. Here the goal is HRT until the average age of menopause. Discussing use of the transdermal patch or progesterone-only options may also reduce vascular risks in smokers on HRT.
In contrast, for postmenopausal women taking HRT for relief of moderate to severe menopausal symptoms, risks may outweigh benefits in smokers, especially those who are older or have cardiovascular risk factors. However, each woman's case should still be evaluated individually. For example, severe hot flashes and sleep disruption impairing quality of life may warrant a low dose or short course of HRT even in smokers. Lifestyle changes, non-hormonal treatments, and addressing the smoking habit should be tried first though.
Ideally, women should be counseled on smoking cessation when HRT is initiated. Quitting smoking significantly reduces cardiovascular disease risk and mortality. Even cutting back on smoking helps. However, stopping smoking should not be an absolute requirement to start HRT. If a woman is unable or unwilling to quit, the focus should be harm reduction with close monitoring.
In summary, while smoking may increase health risks from HRT, it is not an outright contraindication except perhaps in older postmenopausal women or those at high cardiovascular risk. HRT can still be cautiously considered in smokers after a thorough discussion of benefits and risks tailored to individual circumstances. Non-hormonal options should be optimized first. If HRT is used, transdermal over oral routes may be preferred, with the lowest effective doses and shortest duration. Continued efforts to promote smoking cessation are key. Working closely with women to make informed choices about managing menopausal symptoms and risks is the ideal approach.
