@RAFUH - Does this sound plausible?
Technically it can be used with other agents for medical abortion although a rare use now at least in the US.
And then it's given as in injection or intravaginally, not as a pill.
So basically a bunch of crap, but there are physicians and pharmacists of the radical right persuasion that may refuse the medication for this reason.
And some cautious healthcare providers in very red states/areas that will be concerned about being sued - and rightly so in some areas.
There are plenty that already refuse to prescribe/dispense birth control, Plan B, mifepristone, and misoprostol.
Also while I'm at it since I refrained earlier in this thread. Someone made an erroneous assumption about hormonal contraception. It may prevent ovulation, but it can also prevent implantation of a fertilized egg.
