High-dose tirzepatide (10–15 mg/week) is associated with a statistically significant increase in the risk of acute kidney injury (AKI) compared to control treatments.
If you are prescribed high-dose tirzepatide (10-15 mg/week), be aware of a small but statistically significant increased risk of acute kidney injury. Stay well-hydrated, especially if you experience gastrointestinal side effects like nausea or diarrhea, as volume depletion can trigger AKI. Monitor your kidney function as recommended by your doctor, and report any sudden changes in urination or swelling immediately.
Only high-dose tirzepatide (10–15 mg/week) was associated with a significantly increased risk of AKI compared to controls (absolute risk difference: 0.28%; number needed to harm: 357).
Why this rating
Based on a network meta-analysis of 67 RCTs, but the specific finding for high-dose tirzepatide is described as 'sparse-event data with wide credible intervals' and 'hypothesis-generating'.
