The elimination half-life of tirzepatide is about 5 days (roughly 120 hours). This is the elimination half-life of tirzepatide itself; the long duration is what allows once-weekly injection, and the same molecule and half-life apply to both Mounjaro and Zepbound. The FDA label reports no active metabolite with a longer half-life. Individual values can vary somewhat between people.
MOUNJARO (tirzepatide) injection — FDA Prescribing Information, DailyMed ↗Half-life is how long the body takes to clear half a dose. It is not the same as how long a drug test can detect it, and it varies with age, kidney and liver function.

MOUNJARO delays gastric emptying and has the potential to impact the absorption of concomitantly administered oral medications. ( 7.2 ) 7.1 Concomitant Use with an Insulin Secretagogue (e.g., Sulfonylurea) or with Insulin When initiating MOUNJARO, consider reducing the dose of concomitantly administered insulin secretagogues (e.g., sulfonylureas) or insulin to reduce the risk of hypoglycemia [see Warnings and Precautions ( 5.3 )]. 7.2 Oral Medications MOUNJARO delays gastric emptying and thereby has the potential to impact the absorption of concomitantly administered oral medications. Caution should be exercised when oral medications are concomitantly administered with MOUNJARO. Monitor patients on oral medications dependent on threshold concentrations for efficacy and those with a narrow therapeutic index (e.g., warfarin) when concomitantly administered with MOUNJARO. Advise patients using oral hormonal contraceptives to switch to a non-oral contraceptive method or add a barrier method of contraception for 4 weeks after initiation and for 4 weeks after each dose escalation with MOUNJARO. Hormonal contraceptives that are not administered orally should not be affected [see Use in Specific Populations ( 8.3 ) and Clinical Pharmacology ( 12.2 , 12.3 )].
