Life after a GLP-1 · Part 4 of 12
Is there GLP-1 withdrawal, and how long does it stay?
The short answer
Semaglutide has a half-life of about a week and stays in the blood for about 5 to 7 weeks after the last 2.4 mg dose, per the Wegovy label. Tirzepatide’s half-life is about 5 to 6 days. The stopping trials did not measure withdrawal symptoms.12

Questions people ask
Do you get withdrawal symptoms after stopping?
The stopping trials did not measure withdrawal symptoms, so the research cannot say. Many people describe hunger and cravings returning after they stop.
When does appetite come back?
No trial has measured it. Per the labels, medicine levels fall over several weeks.
How long before trying for a baby?
The Wegovy label says to stop at least 2 months before a planned pregnancy. Talk to your prescriber about your own plan.
