A few weeks ago, I specifically asked my rheumatologist about Prednisone and PMR. Obviously it is a complicated question because PMR is a disease that results from an overly aggressive immune system. While the trigger is usually unknown, it is known that the adrenal glands produce too much cortisol (often but not always confirmed by blood tests). Prednisone at higher doses shuts down the adrenals, thereby reducing cortisol and “shutting down” the immune system. One of the reason to taper Prednisone is to gradually bring the adrenal glands back to work. At lower doses, probably 20 mg a day or less, (I found one study done in Europe that confirms that) the adrenals are back working (hopefully) so your immune system should be working normally by the time you wean off it. At 10 mg a day or less, you clearly are not at higher risk for Covid-19 by reason of Prednisone ingestion. HOWEVER, everyone is different and many of us have other risk factors, particularly age. So all posts encouraging social distancing and hand washing are right on as we don’t want to find out what a combination of Covid-19 and PMR will be like. (Caveat: i am not a doctor, but rather a lawyer with enough medical knowledge to be dangerous, so discuss with your provider) .
