Missing a dose happens
You are not alone. Many people miss a GLP-1 dose sometimes. Life gets busy. Travel happens. Routines break.
The good news is that one missed dose is not a disaster. Here is what to do.
The general rule
Most weekly GLP-1 medications follow the same rule:
- Less than 4 days late: Take the dose as soon as you remember
- More than 4 days late: Skip the missed dose. Take your next dose on your regular day
- Never double up: Do not take two doses to make up for one
Medication-specific guidance
Ozempic (semaglutide)
If you miss a dose, take it within 5 days. If more than 5 days have passed, skip it. Take your next dose on your regular day.
Wegovy (semaglutide)
Same as Ozempic. Take the missed dose within 5 days. After that, skip it and wait for your next scheduled dose.
Mounjaro (tirzepatide)
If you miss a dose, take it within 4 days. If more than 4 days have passed, skip the missed dose. Take your next dose on your regular day.
Zepbound (tirzepatide)
Same as Mounjaro. Take within 4 days of the missed dose. After that, skip and resume your normal schedule.
What happens when you miss a dose?
Hunger may increase
GLP-1 medications reduce hunger. When you miss a dose, hunger signals can come back. You may feel hungrier than usual.
This is normal. It will go back to normal after your next dose.
Side effects may return
Some people notice mild nausea or stomach changes after a missed dose. This is because medication levels in your body drop.
Blood sugar may rise
If you take GLP-1s for diabetes, your blood sugar may go up slightly. Monitor it closely. Contact your doctor if it stays high.
How to get back on track
Take your next dose on time
Do not try to catch up. Just take your next dose on your regular day.
Do not change your dose
Do not increase or decrease your dose on your own. Stay on the dose your doctor prescribed.
Watch for side effects
When you restart, you may feel some side effects. This is normal. Eat small, bland meals. Stay hydrated.
What not to do
Do not take two doses
This is the most important rule. Two doses can cause severe nausea, vomiting, and low blood sugar. It is dangerous.
Do not panic
One missed dose will not undo your progress. Weight loss happens over months and years. One week does not change the big picture.
Do not change your dose without asking your doctor
Only your doctor should adjust your dose. Do not increase it to "make up" for a missed dose.
How to remember your doses
Set a phone alarm
Pick a day and time. Set a weekly repeating alarm. This is the easiest method.
Link it to a routine
Take your shot on the same day each week. Link it to something you already do. Like Sunday morning coffee or Wednesday night TV time.
Keep medication visible
Store your GLP-1 pen where you will see it. The front of the fridge works well.
Use a tracking app
Several apps help you track medication doses. They send reminders and log your history.
Tell someone
Ask a family member or friend to remind you. Having a backup helps.

- You miss more than one dose in a row
