High BUN/creatinine ratio on tymlos

Hello, I have been on Tymlos for a month now, and my endocrinologist had me do a panel of blood work to check for kidney issues and my BUN creatinine levels were high. Normal is 12 to 28 and mine was 31 while a month ago it was half that amount. I just got these results back and my visit with my doctor isn’t until April 17. I am going to send her a note, but has anyone else experienced this while on Tymlos and what was the outcome?
