OP, I dealt with this for a few months and just switched my medication. See if that might be an option for you?

If not, call around to local pharmacies as they sometimes have stock although it is getting more and more rare. Walgreens and CVS won't tell you even if they do have it in stock due to their policies but the local ones are usually okay with telling you.

Was also told costco pharmacy is a good route, you don't need to be a member to use it
