Summary
Emergency contraception (EC) prevents pregnancy using four safe regimens. Available data suggest EC is extremely safe, especially compared to pregnancy risks, supporting wider accessibility.
Area of Science:
- Reproductive Health
- Pharmacology
Background:
- Four emergency contraception (EC) regimens exist globally: combined ethinyl estradiol and levonorgestrel, levonorgestrel-only, mifepristone, and intrauterine device insertion.
- These EC regimens are also utilized for long-term contraception, and mifepristone is used as an abortifacient, with established safety profiles in these applications.
Purpose of the Study:
- To evaluate the safety of available emergency contraception (EC) regimens.
- To address the over-medicalization of EC and advocate for increased accessibility.
Main Methods:
- Review of existing safety data for EC regimens used in long-term contraception and as abortifacients.
- Theoretical assessment and practical experience evaluation of EC safety.
Main Results:
- While specific EC safety data are limited, all available regimens are theoretically and practically considered extremely safe.
- The safety of EC is significantly favorable when compared to the inherent risks associated with pregnancy.
Conclusions:
- Emergency contraception (EC) is exceptionally safe, particularly when contrasted with the risks of pregnancy.
- The prescribing process for EC is straightforward, suggesting that making EC available over-the-counter warrants consideration due to its high safety profile.
