What are the possible risks of taking the abortion pill?

Medication abortion is very safe. In fact, it’s safer than many other medicines like penicillin, Tylenol, and Viagra. Serious problems are rare, but like all medicines, there can be risks.
Medication abortion has been used safely for more than 20 years. Serious complications are really rare, but can happen.
These include:
the abortion pills don’t work and the pregnancy doesn’t end
some of the pregnancy tissue is left in your uterus
blood clots in your uterus
bleeding too much or too long
infection
allergic reaction to one of the medicines
These problems aren’t common. And if they do happen, they’re usually easy to take care of with medicine or other treatments.
