Missed GLP-1 Doses: What to Do (and What Not to Do)

Missing a GLP-1 dose happens. Travel, illness, pharmacy delays, and life disruptions are common. A missed dose does not mean treatment failure, and it does not undo your progress.

What matters most is how you respond after a missed dose. This guide explains what to do, what to avoid, and when to reach out for support.

First: Don’t Panic

GLP-1 medications work over time. Missing a single dose does not:

• Cancel treatment benefits

• Cause immediate weight regain

• Mean the medication “stopped working”

Overcorrecting after a missed dose causes far more problems than the missed dose itself.

If You Miss a Dose

If You Remember Close to Your Scheduled Day

• You can usually take the missed dose if it’s within a short window of your scheduled dosing day

• Resume your normal weekly schedule afterward

This keeps spacing appropriate and minimizes side effects.

If Several Days Have Passed

• Skip the missed dose

• Take your next dose on your regularly scheduled day

This is the safest option for your stomach and hydration.

What Not to Do (This Is Critical)

After a missed dose, do not:

❌ Double your next dose
❌ Take doses closer together
❌ Escalate your dose “to catch up”
❌ Inject extra medication

These actions dramatically increase the risk of:

• Nausea and vomiting

• Reflux and bloating

• Dehydration

• Treatment interruption due to intolerance

Why Doubling Doses Backfires

After a missed dose, your body may be less adapted to the medication’s effects. Restarting too aggressively overwhelms digestion and appetite signaling.

This is one of the most common reasons patients experience:

• Severe nausea after “doing fine before”

• Vomiting after restarting

• Feeling like they suddenly can’t tolerate the medication

The medication didn’t fail. The restart was too aggressive.

After Multiple Missed Doses

If you’ve missed more than one dose, restarting may require adjustment.

You may need:

• A lower restart dose

• Slower re-titration

• Extra focus on hydration and smaller meals

This is especially true if:

• You’ve missed 2 or more weeks

• You had side effects previously

• You’re restarting after illness or travel

When to Message Your Care Team

Reach out if:

• You’ve missed more than one dose

• You’re unsure whether to resume or wait

• You had nausea or vomiting in the past

• You’re considering a dose change

Early guidance prevents unnecessary side effects and keeps treatment on track.

Practical Tips to Prevent Missed Doses

• Set a weekly phone reminder

• Link dosing day to a routine (trash day, laundry day, etc.)

• Keep medication supplies visible but safe

• Plan ahead for travel or schedule disruptions

Consistency beats perfection every time.

Key Takeaways

• Missing a dose is common and not a failure

• Take the dose if remembered close to schedule

• Skip and resume if several days have passed

• Never double or escalate doses

• Multiple missed doses may require re-titration

• Ask before adjusting on your own

GLP-1 therapy works best when it’s steady, patient, and intentional.
If something gets missed, reset calmly and move forward.
