 My son loves to fly kites, but my active psoriatic arthritis can sometimes hold me back. Now with Sky Rizzy to treat my skin and joints, I'm ready to go. Sky Rizzy, Riz and Kizumab Rizza, a prescription only 150 milligram injection for adults, helps with less joint pain, stiffness, swelling, and fatigue. For those who also have plaque psoriasis, 90% clearer skin is possible with just four doses a year after two starter doses.
