MEPRON and Kidney function tests - anyone have out-of range?

So, I had a low GFR and high Creatinine. (My Dr. doesn't test the BUN)

They were just out of range. So, I immediately thought it was my new protocol - ie Dapsone, Daraprim, Clindamycin, Rifabutin...

BUT, looking back over the past few years...I see a decline in my GFR after starting Mepron....very slowly declining....so I hadn't noticed it because it has still been in range.

My last Mepron dose was end of July.

Then switched to my new protocol mid August ...and GFR was out of range after the first week of new protocol.
I retested a week later and my GFR climbed a few points and am back in range.


SO....I looked back over the past couple of years...and see there was a slow decline in GFR throughout the time I was on the Mepron (took mepron for 8-9 months, then a few months later for another 4-5 months)

Maybe I prematurely panicked about my new Persister Protocol.
I guess I will know in a couple weeks when I do my safety labs again after Week 1 of that protocol.
