Around one third of Australian women of reproductive age use oral contraception, commonly known as the pill1. And while women will be told about the potential physical side effects of taking the contraceptive, what may not be discussed is the potential mental health side effects.
Some studies have suggested there may be a link between hormonal birth control and depression. Yet a recent review of the research by the journal Contraception shows a “minimal association”. So, what does that mean for Australian women who rely on the pill for their birth control?
Looking at the potential link between birth control and depression
In 2016, a 13-year study from the University of Copenhagen in Denmark was published, following one million girls and women, aged 15 to 34. Over the course of the study, 55.5% of the participants were on hormonal contraception at some stage, with the remaining 44.5% having never used hormonal contraceptives or taken them long before the trial. None of the participants had ever been diagnosed with depression or prescribed antidepressants in the past.
Those who were taking the most popular type of oral contraceptive pill were 23% more likely to be prescribed antidepressants for the first time when compared to non-users. Progestogen-only pills increased the likelihood of an antidepressant prescription even further, to 34%.
However, a more recent review published in the journal Contraception in June 2018 looked at 26 studies on the link between progestogen-only contraception and depression, and appeared to show “minimal association” between hormonal birth control and depression.
These mixed results show there is more research to be done to confirm exactly how hormonal birth control and mental health are related, and while you may want to speak to your doctor about any potential mental health side effects of the pill, it should be one of a number of important factors to consider when making a decision.
