They want the "ask your doctor about..." bits to be heard and followed, I'm guessing. People who thought they just had to live with it will now go in and ask for Bimzelx.
As someone with psoriasis, I seriously doubt anyone with severe plaque psoriasis is going to go from no treatment to monoclonal antibodies. In fact, your insurance won't even pay for it no matter how good it is unless you try other courses of treatment first. The effect is going to be changing from one course of treatment to the next, asking your doctor about it is a call to action.
