Tirzepatide use is associated with specific adverse events in females, including starvation ketoacidosis, menstrual disorders, and postmenopausal hemorrhage.

Women taking tirzepatide should be aware of potential changes in their menstrual cycle, including irregular bleeding or postmenopausal hemorrhage. If you experience these changes, consult your healthcare provider.
