Swelling After Pixel Laser

I had Pixel Laser done on 6/3. My face is very swollen. Doctor prescribed DosPak 21. I'm taking Femara and Nexium. He assures me that even though mine is the "worst" swelling he has seen, it is not permanent. It was not a painful experience, although it really did burn like sunburn afterwards for quite some time. Then the swelling started.

How long will swelling last? Will the DosPak 21 accelerate the swelling? I'm on my first dose today. I have never taken Accutane, but I see it is a Chemo drug, as is Femara. My doctor was not concerned.
