Missed GLP-1 doses and restarting treatment

Start with the exact product

A late weekly injection, two missed weeks and a forgotten daily tablet are different situations. Before looking for a restart rule, check the name and formulation on your prescription. Wegovy tablets and Wegovy injections have different missed-dose instructions even though both contain semaglutide.¹ A social media answer that only says “semaglutide” leaves out information you need.

Write down the last dose you actually took, not the day you meant to take it. Include the date, time, prescribed amount and reason for the gap. Perhaps a refill was delayed, side effects interrupted treatment, or a procedure changed your schedule. Those details help your prescriber answer the real question rather than assume this was one ordinary missed dose.

What the approved labels say

For one missed Wegovy injection, the label uses the time until the next scheduled dose: more than two days away means take the missed dose promptly; less than two days means skip it. For Wegovy tablets, skip the missed tablet and take the next one the following day. If timing falls exactly at a boundary or you are unsure, ask the pharmacist to interpret your instructions.¹

Zepbound uses a different window: the missed injection can be taken within four days of the scheduled dose. After that, skip it. Its label also says not to take two doses within three days of each other.² Ozempic's window is five days; after five days, skip the missed injection and return to the scheduled day.³

These are summaries of approved product labels, not interchangeable rules for every GLP-1 prescription. Do not take extra medication to make up for a gap. If you already took an extra dose or have severe symptoms, contact a healthcare professional or Poison Help promptly; an online calendar cannot assess an overdose.

A longer gap needs a restart conversation

The current Wegovy injection instructions specifically address two or more consecutive missed doses: reinitiate escalation at a lower dose to reduce digestive adverse reactions. The patient guide tells you to contact your healthcare provider about restarting after two or more missed weeks.¹ That is a prescriber decision, not permission to choose a lower dose from someone else's chart.

An isolated missed-dose window for another medicine does not automatically answer how to restart after several weeks. Ask your prescriber to confirm the amount and schedule in writing. Explain any previous nausea, vomiting or difficulty eating, and whether you stopped because of symptoms. Do not assume that having tolerated a dose before the break settles what you should take now.

A compounded vial adds another question

A vial may use a different concentration from the one you received previously. FDA has reported dosing errors with compounded injectable semaglutide, including errors involving measurements and conversions.⁴ A number of syringe units from an old vial is not a universal dose.

Ask the dispensing pharmacist to confirm the current prescription, concentration and measuring device. Request a demonstration if the directions are unclear. This article does not convert milligrams into units or supply a restart schedule for compounded products. Save the pharmacy's written directions with the vial, rather than rely on a screenshot of another patient's instructions.

Make the next refill easier

Before a holiday or insurance change, ask when a refill must be requested and what to do if it arrives late. Keep one simple record of doses actually taken. If several people help with your care, make sure they use the same record so a reminder does not become an accidental second dose.

For technique questions, see the injection itself. For a planned end to treatment, see stopping and maintenance. The useful next step after an unplanned gap is a clear answer for your own prescription, including who to contact if the plan causes problems.
