That’s crazy!
If your doctor already switched medicines call up pharmacy and tell them to get a urgent message to him you can’t afford these medicines and need to change them back ASAP to push it as urgent. Hopefully he will answer but check back with the pharmacy.
If their out they should have a on call. That is unusual.
If that doesn’t work go to a urgent care get it prescribed but be masked and protect your eyes and stay away from everyone. When you get home jump in shower change your cloths.
Better if you stay outside if not too cold and have a younger person go in until your called then tell you when called. If you don’t have a mask use a make shift one.
Also check Goodrx.com key in the name and coupons will pop up and can find some good deals. Sometimes hundreds off but new ones that come out usually don’t have discounts until genetic forms come out.
