Something similar happened to my husband. (Transplanted 7/22). About a month after transplant, he collapsed in the hospital parking garage after Clinic. Turned out his Prograf level was 26. They reduced him to 2 capsules in am and one in pm and hes been good since.
Dialysisgoneforever,It was the strangest thing. We were leaving his weekly clinic when it happened. He had just had blood work 2 hours before and his level was ok. They first thought lab error when they saw his tacro level when he came back through the ER. It was 26 so they admitted him. It went to 15 that night, 9 the next day, and so on til normal a day or 2 later. It was definitely weird. Not sure what "trough level" in answer to your question.
WOW!!?! 45 for a prograf level!! That didn't do any permanent damage to your kidney?
I know that but would a level of 45 damage the kidney even if the level was that high for just for a few hours?
