OKLAHOMA CITY (AP) — A bill designed to reduce the number of abortions performed in Oklahoma by further restricting the use of the abortion pill has cleared the Senate.

The Senate voted 39-6 on Monday for the bill that requires doctors who prescribe the pill, previously known as RU-486, to strictly follow guidelines and protocol authorized by the U.S. Food and Drug Administration. The bill further requires doctors to examine the woman, document certain medical conditions and schedule a follow-up appointment.

Opponents argued legislators have no business telling doctors how to treat their patients.

The Senate sponsor of the bill, Sen. Greg Treat, described himself as "unabashedly pro-life" and says a goal of the measure is to reduce the number of abortions performed in Oklahoma.
