I have read something similar. There are several drugs being touted as helping to control the damage of a cytokine storm. NSAIDS have a small effect and some blood pressure meds (such as Losartan) have an effect as well as Doxycyline.

But the biologics from what I have read are possibly stronger than the others in stopping bad effect.

The common thread here is that it seems all these things dampen our immune response so while it may increase your odds of getting an infection, or getting one that becomes severe....they also can reduce the overactive inflammation that is harming lungs and other organs.
