Wrong medication version from pharmacist?

I ran out of Wellbutrin XL yesterday and dropped off the paper prescription for it this afternoon after work. Pdoc on uses paper, so I read and know wht it said. This evening i go back to pick it up and the price is 75% less than what I've been paying recently and still less than when I started a few years ago. I mention that to the pharmacist and the response was that it must just be since it's December my insurance paid more. I tried to explain my insurance doesn't work that way. I asked if it was the right version, long acting instead of an older one, and she said yes. She told me to go ahead and pay the lesser amount.

I got home and it is indeed Wellbutrin SR 150mg not XL. SR dosing us typically half your daily dose twice a day, sometimes there's exceptions. It's a taller peak and only last half as long as the other. If I wasn't out of Wellbutrin XL and have a horrible headache and have to work I would worry as much. Pdoc's office VM list phone numbers for non life threatening, but its a couple weeks old so it list his partner instead of him. Non-life threatening emergency is an oxymoron statement, but I don't even know if this should be considered one. Should I call pdocs after hours number or call the pharmacy and try to find a time when a different pharmacist is working?
