Shot day

Shot day is the day of the week you take your GLP-1 injection. Semaglutide (Wegovy, Ozempic) and tirzepatide (Zepbound, Mounjaro) are once-weekly medications, so treatment life quickly organizes itself around this day — “Sunday shot day” is a whole genre of community posts.

Why one fixed day

A consistent day keeps the medication level in your body steady and makes patterns visible. Many people notice a rhythm across the week: appetite suppression strongest in the first days after injecting, side effects (if any) clustered in the first 24–48 hours, and hunger or food noise creeping back on days 6–7. That weekly shape is only visible if the anchor day doesn’t move.

Can you change your shot day?

Generally yes — prescribing information for the major GLP-1s allows changing the day of the week as long as enough time has passed since the last dose (for example, Wegovy’s label requires at least 2 days / 48 hours between doses). Confirm the specifics for your medication with your prescriber or pharmacist before shifting.

Shot day rituals

Because it’s weekly rather than daily, shot day works well as a bundle: inject, log the dose and injection site, weigh in, and note how the past week went. One five-minute ritual, once a week, produces a record that makes titration appointments dramatically more useful.
