Can menstrual induction medication be used as emergency contraception within 72 hours?


Today was the first time I had sexual intercourse with my boyfriend.
We weren't able to fully penetrate, but halfway through, my boyfriend suddenly ejaculated (afterward, I forgot to check if the condom was broken; it appeared intact to the naked eye).
Should I take emergency contraception? Would taking a menstrual induction pill have the same effect? Thank you.

No, you should use a specific emergency contraceptive pill, as the concentrations of the medications differ.

More Info


Menstrual induction pills are not designed to serve as emergency contraceptives. Emergency contraception (EC) is specifically formulated to prevent pregnancy after unprotected intercourse or contraceptive failure, such as a broken condom. The most common forms of emergency contraception include hormonal pills like levonorgestrel (Plan B) and ulipristal acetate (Ella), as well as the copper intrauterine device (IUD).

In your situation, since there was a possibility of sperm exposure during intercourse, it is advisable to consider taking an emergency contraceptive pill as soon as possible. The effectiveness of these pills is highest when taken within 72 hours after unprotected intercourse, but some options, like ulipristal acetate, can be effective up to 120 hours after.

Menstrual induction pills, on the other hand, are typically used to induce menstruation or manage menstrual disorders. They contain hormones that can affect the menstrual cycle but do not have the mechanism to prevent ovulation or fertilization. Therefore, relying on menstrual induction pills as a form of emergency contraception is not only ineffective but could also lead to unnecessary side effects or complications.

If you are concerned about the possibility of pregnancy, it is crucial to consult with a healthcare provider. They can provide guidance on the appropriate use of emergency contraception and discuss any potential risks or side effects associated with the medications. Additionally, if you have any ongoing concerns about your menstrual cycle or reproductive health, a healthcare professional can offer tailored advice and support.

In summary, if you are worried about the risk of pregnancy after your recent sexual encounter, it is best to take an emergency contraceptive pill rather than menstrual induction pills. Always consult with a healthcare provider for the most appropriate and effective options based on your individual circumstances.
