Do Beta Blocker Increase Potassium Level?

I am seeing a new doctor and I am taking an otc supplement with potassium for kidney stones. I was taking Lisinapril which raises potassium and this doctor changed my RX to a beta blocker, metaprolol. I checked on WebMD and it said the beta blocker raises potassium, but my doctor says no. Which is correct?
