@sweethighland Hi sweet highland- so the dose was 100mg till I got better. ( plus the decreasing dose of prednisone. I know that sounds vague right, but I have been dealing with this for so many years that when I got so sick in 2023 the UMASS doctors and I did virtual visits as I was in Florida at the time which is a good 2000 miles away from my team in Massachusetts. I was also on a strong cough medicine which I am thankful about. If I had to think of a time frame it was probably a good month with close telephone monitoring . I had had an x ray in Connecticut prior to leaving ( at an ER) so they had access to that. After that I have been on Levoquin with nebulizing until my most recent visitor MRSA pneumonia. Now I will tell you I can no longer take doxycycline as I recently developed an allergy to it- swollen mouth /face and body rash. UMASS has noted that in my file!! That’s actually the only drug I have developed an allergy to!! Wishing you well. Irene5
