Cimzia, like Enbrel and Humira, is a TNF inhibitor. TNF inhibitors are often the first biologic treatment in immune system disease due to their proven efficacy, safety profile, and cost. Don’t get too wrapped up in looking at the side effects of the medication, as the most adverse ones are often just worst case scenarios. The most common side effect of biologics is reduced immune resistance, leaving one more susceptible to opportunistic infections. So wear a three layer surgical mask during cold and flu season, and wash your hands with soap and water often, and you should be fine. I started on Humira in 2020, and we all remember how bad a year that was. Even continuing on through 2021, I didn’t get a single cold, thanks to precautionary measures such as masking in public and hand washing. And avoiding sick people.
