Do you continue finerenone in a patient with CKD and type 1 diabetes whose eGFR has fallen 35% one month after starting 10 mg, if potassium is normal and UACR is falling?

Generally speaking, if the decline in eGFR is >30%, then a reasonable approach is to recheck the GFR and, if it has stabilized, then to observe/follow according to clinical judgement, while at the same time making sure BP is NOT low and that the patient is not volume depleted (and making adjustments...

A dip in eGFR is expected at 1-3 months with finerenone. I would continue it and follow the patient closely.
