> Why are EpiPen substitutes not allowed? My understanding is if the prescription says "EpiPen" (or any non-generic drug brand name) the pharmacist must provide an EpiPen (or the brand-name drug). If the prescription says "epinephrine auto injector" or "EpiPen or generic," then the substitution is allowed. > Are the products that different? IIRC, they all the current alternatives deliver the same medicine, but they use different injector mechanisms to do so. I think the last alternative withdrew from the US market for some reason, because their mechanism wasn't as reliable with dosing. IIRC, EpiPen's mechanism is apparently off-patent, so a true generic could enter the market if approved.
