By all means, see the PA. As Jerry said, they are overseen by a doctor, and you are primarily interested in refills at this time, anyway.

My family practice doctor works with a PA. We can be seen by the PA almost anytime on a "come in right away" basis. It's great for minor stuff that you need a script for (antibiotics for a sore throat) or muscle pull that you want to go to PT for, etc.

And my knee surgeon has one too--but that PA was working as an orthopedic resident at the hospital on Saturday when I was picking hubby up after his latest heart caths and stents. I called my doc as I had a 4" section of my knee incision filled with dried blood when I woke up that AM. He said go downstairs to ER--I know a resident working today and I'll have him take care of you. It was his PA, so apparently he is studying to be a doc now! And the knee: after careful cleaning, he discovered a very tiny scratch right next to the incision. Apparently one of my kittens had scratched me and I didn't notice it was bleeding. It bled right into the incision area! The PA glued me back together and it healed nicely.
