Tirzepatide utilization has rapidly displaced other glucose- and weight-lowering medications in the US, with its uptake being steeper and more sustained than previous GLP-1 receptor agonists.

Tirzepatide is currently the fastest-growing and most prescribed glucose- and weight-lowering medication in the US, rapidly replacing older drugs like metformin and other GLP-1s. If you have T2D or obesity, this drug is becoming the standard of care, but access may be difficult due to shortages. Prioritize securing a prescription early if eligible.
