A member asked:

Bun levels went from 11 to 19 after raising methotrexate to 25 mg. what does that mean? is this concerning?

2 doctors weighed in across 2 answers

Don't worry: Lymphocyte counts, neutrophil counts, and blood urea nitrogen fluctuate chaotically in everyone, from day to day and as we meet various stresses and perhaps experience subclinical infections.

Probably nothing: The BUN has little meaning. Was there any change in the serum creatinine level? That is the important value.
