Data Following subcutaneous administration of a single 5 mg dose to 11 healthy lactating adult females, the concentration of tirzepatide in breast milk was found to be undetectable (limit of detection in breast milk 4 ng/mL) in 164/171 samples assayed

In one case, a patient regurgitated a significant volume of gastric contents after the induction of anesthesia, despite having ceased taking the medication two days before surgery and fasting from solid foods for 20 hours beforehand.10 This led to the proposal that patients should suspend medication use four weeks prior to surgery.10 Another case involved a patient who, after fasting for 18 hours before the procedure and while on semaglutide, experienced intraoperative pulmonary aspiration.11 A further report detailed a case where an EGD, scheduled as part of bariatric surgery preparations, was canceled due to excessive gastric food retention.12 Collectively, these case reports underscore the potential risks involved with the use of GLP-1 agonists prior to surgical procedures
