I'm on Xeljanz, which is the same type of medication as Rinvoq, but not as selective. The one advantage JAK inhibitors like Rinvoq and Xeljanz have over biologics is that they have a fairly short lifespan in the body. So you can pause the medication the moment you begin feeling symptoms of an illness coming on. Unfortunately, you're still looking at about three days before your immune system begins to bounce back from the suppressant effects of the Rinvoq, and with the common cold, that's the prime incubation period. My best advice is to inform everyone around you of your weakened immune system so that they can be more aware of taking greater preventative measures themselves; wear a good three ply surgical mask, or KN95 type mask, when in public during cold and flu seasons; scrupulous hand washing and sanitizing; stay away from sick people.
