Tirzepatide may trigger exercise-induced anaphylaxis, which resolves upon discontinuation of the drug.

A patient developed exercise-induced anaphylaxis after initiating tirzepatide, a dual GIP/GLP-1 receptor agonist. After discontinuing tirzepatide, the exercise-induced anaphylaxis resolved. This suggests a causal relationship between tirzepatide and exercise-induced anaphylaxis.

Frequently Asked Questions

What is tirzepatide?▼

Tirzepatide is a dual glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1 receptor agonist used for type 2 diabetes and weight management.

Can exercise-induced anaphylaxis be caused by medications?▼

Yes, certain medications can act as cofactors, increasing the risk of exercise-induced anaphylaxis, as seen in this case with tirzepatide.

Does stopping tirzepatide always resolve exercise-induced anaphylaxis?▼

In this single case report, discontinuation led to resolution, but more evidence is needed to confirm this effect in other patients.

Is exercise-induced anaphylaxis common with GLP-1 receptor agonists?▼

This is a rare reported case; no widespread evidence suggests a common association, but clinicians should be aware of the potential risk.
