When the message came out about HCQ two months ago, hospitals ordered the double amount as normal, and that was enough to empty the stockpiles of some distributors. The production can get easily ramped up and they do just that, but in the days and weeks ahead some planned distribution involving the national stockpile and buying from abroad is needed. Some governors use this to restrict the distribution more than necessary, but it will be hard to prove that they have done it to force people to wait for the vaccines.
