Mechanically, the relevant risk chain is vomiting to volume depletion to reduced renal perfusion to a rising creatinine, which is how most acute renal events in this class occur.
Repeated vomiting is the mechanism behind most reported acute kidney injury in this class. The renal event is a volume event, not a direct toxicity.
Stated carefully, fluid lost in vomit carries sodium at roughly 60 millimoles per litre and potassium at rather less, so replacing it with plain water alone dilutes plasma sodium rather than restoring balance.
Volume depletion as the mechanism for acute creatinine rise is basic renal physiology and explains the pattern of renal reports in this class.
Nothing here is medical advice.
Small frequent sips of an oral rehydration solution, not large volumes of water.
