Torie, few, if any, insurers cover OTC drugs so it's hardly fair to blame Obamacare for that provision.
Just because something is available over-the-counter doesn't mean that it can't be purchased through insurance with a prescription.
If the insurance does, but I've never had a plan which covered OTC drugs even with a prescription. Heck I remember being specifically declined coverage on a prescription that was written back in 1985, so non-coverage of OTC drugs is hardly anything new. Nor is people who want to stop having a drug receiving insurance coverage trying to get a prescription drug turned into an OTC drug anything new. The only thing new is that the motivation for seeking the change is not economic.
