Interesting. By coincidence, I am taking acyclovir right now, 400 mg x 3/day. We'll see if it make a difference.

BTW, for background, I was diagnosed with PMR and/or GCA around Feb 2, 2023, and after an initial 20 mg/day of Prednisone was ineffective, the dosage was increased to 60 mg/day. That was on March 2, 2023. Weekly shots of Acterma (tocilizumab) were started about 5 weeks later, in early April, and Prednisone tapering was begun. Now, as of 10/15/2023, I'm down to 0.5 mg/day of Prednisone. The Actemra shots will likely continue for another year or so.
