Well if I owned a pharmacy I certainly wouldn’t want to dispense a drug indicated for adult use by the drugs maker to the parent of a child. Recipe for a lawsuit which the pharmacy or the drug manufacturers would lose. Because … parents … children.

As a person dependent on a drug to stay alive I fully understand your frustration.
