Adherence
Tirzepatide is associated with injection-site reactions, particularly pain, which are consistent with the class of GLP-1/GIP agonists and are typically mild and transient.
Injection site pain is a common side effect of tirzepatide. It is usually mild and goes away. Proper injection technique and counseling can help reduce this discomfort and help you stick with your treatment.
ModerateSupportsMEDIUM confidence
Injection-site reactions included 19,334 reports... Injection-site pain particularly prevalent... These events are typically mild and transient in nature.
Why this rating
Based on FAERS data, which reflects reporting bias but shows consistent trends.
