I dont know if this has been covered in deatil, I could not find it. My family owns a Pharmacy so I figured I could clear up some stuff.
Ethex got shut down for not being up to code on their generic formulas, or maybe one. And another as well. This is more to do with putting political pressure on Oxycodone than anything. Most pharmacies are completely out of OXycodone 30/15mg, and will be for some time. It will sort its self out, as many comapnies make it. Also, Ethex will open again when it becomes more compliant.
I expect similar things to continue to happen as the new legislation against opioids progresses. In FLorida its been bad. My dad had over 300 phone calls in one day looking for OXy. Some blond also came to the store after close to offer "anything" for some 30s.
So, even though you are paying shit prices, if I did roxis, I would start hoarding them!
