Rising concerns over pill's impact on mental health
Prescription rates for oral contraceptives are declining in many developed nations, driven partly by growing fears about their effects on mood and mental well-being. Social media movements like #quittingbirthcontrol have amplified these concerns, though experts warn that misinformation is also spreading alongside legitimate worries.
Declining use and social media backlash
Recent data shows a sharp drop in pill usage. In England, uptake fell from 39% in 2020-2021 to 27% in 2021-2022. Similar trends are seen in the U.S. (31% in 2002 to 24% in 2017-2019), Canada (23% to 11% from 2006-2016), and Australia (23% to 11% from 2008-2016). While some influencers advocate abandoning hormonal contraception entirely, health professionals caution this could contribute to rising abortion rates.
Mixed scientific findings
Research on the pill's mental health effects yields conflicting results. A landmark 2016 Danish study tracked over a million women aged 15-34 for 14 years, finding those on the combined pill were 70% more likely to be prescribed antidepressants within six months, while mini-pill users faced an 80% higher risk. A 2023 UK Biobank analysis echoed these findings, reporting a 71% increased depression risk two years after starting the pill.
Yet other studies show minimal or no links. Ohio State University's review of 26 studies found only a "minimal" connection between progestogen-only methods and depression. Swedish clinical trials involving 200-340 women concluded the combined pill did not worsen mood or cause depression. Experts attribute discrepancies to variations in pill types, methodologies, and subjective mental health measurements.
"The impact of hormones on the brain is complicated. For some, the pill improves well-being; for others, it may trigger anxiety."

How the pill may affect the brain
Oral contraceptives contain synthetic hormones that disrupt natural menstrual cycles. Combined pills use artificial estrogen and progesterone, while mini-pills rely solely on progestins-most derived from testosterone. These hormones influence serotonin, the brain's "mood-booster" neurotransmitter. A Danish study found pill users had 9-12% lower serotonin signaling, twice the reduction caused by SSRI antidepressants.
Other potential mechanisms include disrupted production of allopregnanolone, a hormone regulating mood and stress responses. Animal studies suggest pill use may lower allopregnanolone levels, though human implications remain unclear. Additionally, the pill blunts cortisol responses to stress, which could paradoxically increase anxiety or depression.
High-risk groups and alternatives
Adolescents appear particularly vulnerable. The Danish study showed 15-19-year-olds on the combined pill were 1.8 times more likely to be prescribed antidepressants; mini-pill users faced a 2.2-fold risk. A Swedish registry analysis found 12-14-year-olds were 240% (combined pill) and 190% (mini-pill) more likely to receive antidepressants within a year.
Women with prior depression or psychiatric conditions also face higher risks. Experts recommend monitoring mood changes for months after starting or switching pills. With over 30 combined pill brands and varying hormone combinations, finding the right fit is "individualized treatment," says Bitzer.
Non-hormonal or low-dose alternatives include condoms, IUDs (copper or hormonal), vaginal rings, and sterilization. For some, the pill's benefits-like managing endometriosis or PMDD-outweigh risks. Pregnancy itself carries mental health risks, with unplanned pregnancies linked to higher depression rates.
Expert advice and next steps
OBGYNs emphasize self-awareness and open dialogue with healthcare providers. "If you notice mood changes, discuss alternatives," advises Helena Kopp Kallner of Danderyd Hospital. While most women tolerate the pill without severe issues, a small percentage experience significant mental health effects.
Sarah E. Hill, an evolutionary psychologist who documented her own struggles in How the Pill Changes Everything, urges patience: "Find a contraceptive method that aligns with who you want to be. With time and self-compassion, you'll find what works."
