Hormonal contraceptive labels omit many risks, a review argues

Hormonal contraceptive labels leave out many documented side effects, this review argues. Eleven authors surveyed studies on cancer, mood, bones, blood clots and HIV. They ask the FDA to remove the injectable contraceptive DMPA.

Key Findings

  • In the 2015 Morrison meta-analysis, HIV hazard ratios versus no hormonal contraception were 1.50 (95% CI 1.24–1.83) for DMPA and 1.03 (95% CI 0.88–1.20) for combined oral contraceptives.
  • ECHO trial, continuous-use analysis, DMPA versus levonorgestrel implant: HIV hazard ratio 1.29 (95% CI 0.98–1.71). The trial's investigators concluded they found no substantial difference in HIV risk among methods.
  • Large cohort studies the review cites report breast cancer relative risks from 1.2 to 1.37 with hormonal contraceptive use. A registry study of progestogen-only contraceptives reported 1.19.
  • Among adolescents and young women (mean age 21 years), the review reports suicide attempt relative risks of 1.91 for combined oral contraceptives and 3.28 for the patch.

Interpretation

This is a literature review by authors from medical and family planning groups. They examined studies on cancer, mood, bone health, blood clots and HIV in women using hormonal birth control. The authors say the DMPA-HIV link is clearly proven. They describe some other links more carefully, using words like suggest and appears. The authors say the ECHO trial results match the 2015 Morrison study linking DMPA to higher HIV risk. The findings support larger studies on these links and clearer risk information for patients.

RRM Context

Restorative reproductive medicine calls these drugs suppressive medications. Its goal is to find the cause of a problem and work with the cycle. The review describes the drugs in similar terms: strong man-made steroids that disable a normally working body. No disease is being treated. The review names fertility awareness methods as its alternative.

Abstract

Hormonal contraceptives have been on the market for over fifty years and, while their formulations have changed, the basic mechanism of action has remained the same. During this time, numerous studies have been performed documenting side effects, some of which appear over time, some within weeks or months, but all can have a serious impact on health and quality of life. An effort was made to perform a series of comprehensive literature surveys to better understand immediate and long-term side effects of these agents. The results of this literature review uncovered a number of potential side effects, some of which are acknowledged and many of which are not noted in the prescribing information for these agents. Among the unacknowledged side effects are: an increased risk of HIV transmission for depot medroxyprogesterone acetate (DMPA), and for combination contraceptives breast cancer, cervical cancer, Crohn's disease, ulcerative colitis, systemic lupus erythematosus, depression, mood disorders and suicides (especially among women twenty-five years of age and younger, in the first six months of use), multiple sclerosis, interstitial cystitis, female sexual dysfunction, osteoporotic bone fractures (especially for progesterone-only contraceptives), and fatty weight gain. Misleading prescribing information regarding cardiovascular and thrombotic risks are also noted. Women seeking birth control have a right to be informed and educated about risk avoidance through the use of effective nonhormonal methods like fertility awareness methods. In one case-that of DMPA-the increased risk of HIV acquisition has been conclusively demonstrated to be both real and unique to this drug. Considering the availability of numerous alternatives, there is no justification for the continued marketing of DMPA to the public.

Summary

We reviewed the effect of hormonal contraceptives on women's health. A number of potential side effects were noted including increased risks of breast cancer, cervical cancer, inflammatory bowel disease, lupus, multiple sclerosis, cystitis, bone fractures, depression, mood disorders and suicides, fatty weight gain, and female sexual dysfunction. With the long-acting injectable contraceptives there is an increased risk of getting HIV. Misleading prescribing information regarding the risks of heart attacks, strokes and blood clotting problems were also noted. Women seeking birth control have a right to know about how to avoid these risks by using effective hormone-free Fertility Awareness Methods.
