(CNN) — A Louisiana bill would classify the abortion-inducing drugs misoprostol and mifeprostone as Schedule IV controlled dangerous substances in the state, placing them in the same category as highly regulated drugs such as narcotics and depressants.

The amendment that would classify the drugs as Schedule IV substances was added to a Senate bill that would make it a crime to give abortion medication to a person without their consent.

The bill’s sponsor, Republican state Sen. Thomas Pressly, said he proposed the legislation after his sister was given misoprostol against her will.

Abortion is already banned in Louisiana with no exceptions for rape or incest.

The bill sparked outcry from a group of nearly 270 Louisiana physicians, health care providers and medical students, who signed a letter to Pressly expressing concerns over the reclassification.
