What should I do if I miss my GLP-1 dose?

If it’s only been a few days, most GLP-1s allow you to take the missed dose once you remember. If too much time has passed, skip it and resume your normal schedule. Never double up doses.

Will missing one dose affect my progress?

Usually not. GLP-1s stay active in your system for several days, so a short delay rarely changes outcomes. You might notice mild hunger or appetite changes, but your progress will pick back up once you resume.

Can I move my injection day?

Yes—most GLP-1s allow flexibility. Just make sure there’s at least 48 hours between injections before switching to a new weekly schedule.

What happens if I miss more than one dose?

Missing several doses can cause your body to lose tolerance. You may need to restart at a lower dose to minimize side effects like nausea. Check with your provider before resuming.

Should I double my next dose if I forget one?

No. Taking two doses too close together can increase the risk of nausea, vomiting, and other side effects. Skip and continue your normal rhythm instead.

When should I call my provider?

Reach out if you’ve missed two or more weekly doses, feel unusually sick after restarting, have diabetes with rising blood sugar, or want to permanently change your injection schedule.

It happens to everyone. Here’s what to know—and what not to panic about.

Even the most organized person can miss an injection day. Maybe you traveled, got sick, or just forgot. The good news: for most GLP-1 medications, missing one dose usually doesn’t derail your progress. But the details depend on which GLP-1 you’re taking and how long it’s been since your last dose.

Let’s walk through what really happens in your body, when it matters, and how to safely get back on track.

Important: GLP Winner is not a medical provider. The information below is based on publicly available manufacturer and prescriber guidelines. Always talk with your licensed healthcare provider before making any changes to your treatment schedule or medication use.

Why Missing One Dose Usually Isn’t a Big Deal

Most modern GLP-1 medications—like semaglutide (Ozempic®, Wegovy®), tirzepatide (Mounjaro®, Zepbound®), and dulaglutide (Trulicity®)—stick around in your body for days. Their half-life (how long it takes for half the drug to leave your system) is long—often 4–7 days or more (NCBI).

That means if you’re late by a day or two, there’s still active medication working in your body.

You might notice:

Slightly more hunger than usual
A small bump in appetite or cravings
Minor changes in blood sugar if you’re using it for diabetes

But you won’t suddenly “lose” your progress. GLP-1s work gradually—just as results build slowly, they also fade slowly.

What the Guidelines Say About Missed Doses

Each GLP-1 has its own instructions for what to do if you miss a dose. Here’s a simplified breakdown:

Semaglutide (Ozempic®, Wegovy®)

If you miss your shot, take it as soon as you remember—as long as it’s within 5 days of your scheduled injection. After that, skip it and take your next one on your regular day (NCBI).

You can shift your injection day if you need to, but make sure there’s at least 48 hours between doses (NCBI).

Tirzepatide (Mounjaro®, Zepbound®)

You have up to 4 days (96 hours) to take a missed dose. If more than 4 days have passed, skip it and resume your normal schedule. Never double up (Mayo Clinic).

Dulaglutide (Trulicity®)

If your next scheduled dose is at least 3 days away, you can take the missed dose as soon as you remember. Otherwise, skip it and resume on your next scheduled day (NCBI).

Liraglutide (Victoza®, Saxenda®)

Because it’s a daily injection, simply skip the missed dose and take your next one as usual. If you’ve missed more than a few days, check with your provider before restarting—you may need to lower the dose temporarily (Mayo Clinic).

Oral Semaglutide (Rybelsus®)

If you forget your pill, skip it and go back to your regular schedule the next day (Mayo Clinic).

What to Expect After Missing a Dose

Missing one weekly injection doesn’t cause a crash—but here’s what can happen over time:

Appetite control may fade. You might feel hungrier within a few days.
Blood sugar may rise slightly. If you use GLP-1s for diabetes, keep an eye on your glucose.
GI symptoms can return when you restart. After a longer break, nausea or bloating can flare back up when you resume your dose (PMC).
Weight loss may pause. GLP-1s need steady blood levels to maintain appetite and glucose effects. A long lapse might temporarily slow your progress.

For most people, a single missed dose isn’t a big deal. But missing multiple doses in a row can require a “reset”—usually restarting at a lower dose and ramping back up to avoid side effects (PMC).

What Not to Do

Here’s what doctors and pharmacists consistently warn against:

Don’t double up to “make up for lost time.” That can cause nausea, vomiting, and severe GI discomfort (MDPI).
Don’t shorten the gap between injections below 48 hours. That can spike side effects.
Don’t restart at your highest dose if you’ve missed multiple weeks—check with your provider about whether to step down first.
Don’t panic. One slip isn’t failure—it’s normal. These medications are forgiving because of their long half-lives.

When to Call Your Provider

Reach out to your healthcare professional if:

You’ve missed two or more weekly doses in a row
You’re feeling unusually nauseated or dizzy after restarting
You have diabetes and notice blood sugar running higher than normal
You need to permanently change your injection day or adjust timing around travel
You’re not sure which rules apply to your specific GLP-1

Can You Move Your Injection Day?

Sometimes you may need to shift your weekly shot to a new day. Most manufacturers allow this—but you must wait at least 48 hours between doses (NCBI).

After that, simply continue on your new schedule. It’s safest to do this after you’ve reached your maintenance dose, not during the dose-increase phase.

The Bottom Line

Missing a GLP-1 dose doesn’t erase your progress, but timing matters. Here’s the short version:

You can usually make up a dose if you’re within a few days.
Skip it if it’s been too long—don’t double up.
Resume your normal schedule and stay consistent going forward.
If you miss multiple doses, check with your provider before restarting.

These medications work best when used regularly—but they’re designed to be forgiving if life happens. The key is to restart safely, not rush.
