I just had to wait for 3 weeks to get a refill on my daily asthma inhaler, one and a half of them without my meds. There was some sort of supply issue with my regular one, so had to get a new one prescribed. I had to deal with going back and forth with the pharmacy, doc office, and insurance company to finally get the approved brands/prior authorizations figured out. I'm glad my asthma isn't too bad right now despite being allergy season.
I'm taking a wild guess here, but I'm guessing that folks in places with universal healthcare don't have to deal with this sort of bullshit.
