Ok. I am busted. When on this site or other sites I use the word Prednisone or steroid equivalent. My wife was diagnosed with GBM in Jan2021. I had a double covid shot in february 2021. I only did it to protect my wife. By end of Feb I could not get out of bed. I was spending countless hours trying to understand everything I could get my hands on for alternatives to GBM treatments. Including Dexamethasone. They started my wife on 8mg night and morning. She was on that until after surgery. They gave her 4mg tablets of Dex and just kept them coming. Then they needed us to lower dose. So sent refillable 30 day prescription of 2mg. I had several bottles full of steroids. I spent Feb-Apr trying to figure out my condition. 2 orthopedic Dr's. my GP. even my gastroenterologist. Finally ran across information thru google on corticosteroid use for PMR as it was referring to my wife's taper. I thought thats it. Thats what I have. I already had DEX. So I decided to try it. I took 4mg that morning. By late afternoon I had no pain. I took 4mg for 2 days and then went 3mg for 2 days with no pain. At a week I dropped to 2mg and could just barely feel the discomfort. I got my PA on a conference appt and said I know what I have and I need a prescription. She lectured me for 10 min and said she would do 30 days if I sent her a copy of my appt with a Rhumy. I went to Mayo for my Rhumy. Mayo runs every test in the book. Plus some. He agreed with my diagnosis. He did not want to give me Dex but I convinced him I knew the risks. He felt I did. I was on 6 months and got off. I have not been back to my Rhumy. My PA handles it from here. But I have a stock pile of Dex. Its like gold. I keep it in the safe. So when I answer on these sites I always say prednisone. I use the conversion of 5. Even though .75 dex = 5mg Prednisone. Dex has a longer half life. So my 4mg starting dose was the rough equivalent of 20mg prednisone. So I use the 20mg as my talking point. I think its Marilynn is on 3mg dex. thats rougly 15mg prednisone. My wife's body has been severely compromised by Dex and she is on 1mg Dex. I have never taken Prednisone only the Dex.
