If you've missed a dose of your weight loss medication, don't panic. What to do next depends on how long it's been, and in most cases, it's a simple fix. Wegovy (semaglutide) is now available in the UK in two formats: the familiar once-weekly injection pen, and a newer once-daily tablet. The two have completely different missed dose instructions, so knowing which applies to you matters.
This guide explains what to do in each case, how a missed dose affects your treatment, and the practical habits that stop it happening again.
What is the Wegovy injection dosage schedule?
Wegovy injection is given as a once-weekly subcutaneous injection using a pre-filled pen, into the abdomen, thigh or upper arm. It can be taken at any time of day.
Treatment follows a structured dose escalation plan rather than starting at the full dose. This gradual build-up is designed to reduce the likelihood of gastrointestinal side effects such as nausea:
Dose escalationWeekly doseWeek 1–40.25 mgWeek 5–80.5 mgWeek 9–121 mgWeek 13–161.7 mgFrom week 17 (maintenance)2.4 mgFrom week 21, for adults with obesity, if needed7.2 mg
Consistency in weekly timing is what keeps drug levels in your body stable and supports treatment effectiveness. A missed dose creates a gap that can allow those levels to drop, which is why the guidance below exists.
If you do need to move your injection day, the day of weekly administration can be changed as long as there are at least 3 days (more than 72 hours) between doses. Once you've chosen a new day, stick to it.
What to do if you miss a Wegovy injection
The first thing to establish is how many days have passed since the dose was due.
- Within 5 days of the missed dose: inject the missed dose as soon as you remember, then carry on with your usual weekly schedule.
- More than 5 days after the missed dose: skip the missed dose entirely and take your next injection on your regular scheduled day.
Never take two doses in the same week to make up for a missed one. Doubling up increases your risk of side effects without improving results.
If you've missed several doses, speak to your prescriber before restarting as reducing the dose you re-start on may be appropriate.
Always check the patient information leaflet supplied with your pen for guidance specific to your strength and device.
How does missing a Wegovy injection affect treatment progress?
One missed injection, managed correctly, is unlikely to derail your overall treatment plan. Semaglutide has a long half-life of around one week, which is precisely why the 5-day window exists as there's still a meaningful amount of medication in your system.
Repeated interruptions are a different matter:
- Frequent gaps allow drug levels to fall, which can reduce appetite suppression and slow your progress.
- Missing doses during the escalation phase may delay how quickly you reach your maintenance dose.
After a longer break, your prescriber may recommend restarting at a lower dose and building back up rather than resuming where you left off. This is a clinical judgement based on how long the gap was and how well you tolerated treatment before it.
If you've missed more than one dose in a row, get in touch with your prescriber rather than guessing. A short conversation avoids weeks of avoidable side effects or lost progress.
What is the recommended Wegovy tablet dosage schedule?
Wegovy tablets are a newer format, approved by the MHRA in June 2026 and available privately in the UK. Unlike the injection, they are taken once daily, and the schedule is different:
- Starting dose: 1.5 mg once daily
- Escalation steps: 4 mg, then 9 mg, then 25 mg, with a minimum of one month at each dose level
- Maximum dose: 25 mg once daily — never take more than one tablet a day to achieve a higher dose
How you take the tablet is as important as when. The tablet must be swallowed whole (not split, crushed or chewed) on an empty stomach, after a fasting period of at least 8 hours, with no more than half a glass of water (up to 120 ml). You then need to wait at least 30 minutes before eating, drinking, or taking any other oral medicines. Waiting less than 30 minutes reduces how much semaglutide your body absorbs.
For most people this means taking the tablet first thing in the morning, before breakfast.
What to do if you miss a Wegovy tablet dose
This is where the tablet differs most from the injection, and it's worth reading carefully:
- If you miss a tablet dose, skip it and take your next tablet the following day as normal.
- Do not take the missed tablet later the same day. Because the tablet requires an 8-hour fast beforehand and a 30-minute wait afterwards, a dose taken mid-day is unlikely to be absorbed properly.
- Do not take two tablets to make up for a missed one. This does not improve outcomes and may increase the risk of adverse effects.
Always check the patient information leaflet supplied with your tablets for instructions specific to your dose.
How does missing a Wegovy tablet dose affect treatment progress?
An occasional missed tablet, handled as above, is unlikely to disrupt your regimen. But because the tablet is taken daily and absorption is more variable than with the injection, consistency matters more:
- Frequent missed doses lead to inconsistent drug levels and reduced overall effectiveness.
- Regular gaps during the escalation phase can slow your progression toward the maintenance dose.
If you've missed several consecutive days, speak to your prescriber before resuming as your dosing may need reviewing.
Log any disruptions and mention them at your next check-in so your treatment plan stays accurate.
How to avoid missing a Wegovy dose
Choosing and sticking to a regular dose day or time
For the injection, pick a day of the week that genuinely fits your routine, not the day you happened to start. A Sunday morning works well for many people because it's predictable.
For the tablet, anchor it to an existing morning habit, before your first coffee or breakfast, so the 8-hour fast happens naturally overnight.
Consistent timing keeps drug levels stable and gets the most out of your treatment. Don't change your dose day or time without checking with your prescriber first, as this can accidentally create a gap.
Using reminders and tracking tools to stay on schedule
- Set a recurring calendar reminder or phone alarm for your injection day or daily tablet time.
- Use a medication tracking app to log each dose, so you have an accurate record and can spot gaps.
- Keep a physical calendar or medication log somewhere visible — a note on the fridge is surprisingly effective.
- Consider a buddy system, where a partner or friend prompts you, particularly in the first few weeks while the routine is still forming.
- Include the date, dose taken and any notes on side effects in your log. It's genuinely useful information to bring to your review.
Seeking support and guidance to maintain your medication regimen
If you're struggling to stay consistent, tell your prescriber or pharmacist. Adherence problems usually have a practical cause (an awkward dose day, side effects, travel, or simply forgetting) and most have a practical fix.
Your patient information leaflet covers missed doses and administration in detail and is worth keeping to hand. Beyond that, regular check-ins let your clinical team spot adherence issues early and adjust your plan before progress stalls. If missed doses are becoming a pattern, your prescriber can review your dosage schedule, discuss what's getting in the way, and suggest strategies that fit your life.
Staying engaged with your treatment and honest about the weeks that didn't go to plan is what supports long-term results.
Frequently asked questions
What happens if I miss a Wegovy injection by one day?
Take it as soon as you remember and continue with your usual weekly schedule. Anything within 5 days of the missed dose can simply be taken late.
Can I take two Wegovy doses in one week to catch up?
No. Taking two doses in the same week increases your risk of side effects, particularly nausea and vomiting, and does not improve your results.
What if I've missed more than one Wegovy injection in a row?
Contact your prescriber before restarting. Depending on how long the gap has been, they may recommend re-starting at a lower dose and escalating again rather than resuming your previous dose.
Can I take a missed Wegovy tablet later the same day?
No. Skip the missed tablet and take your next one the following day. The tablet needs an 8-hour fast beforehand and a 30-minute wait afterwards, so a dose taken later in the day won't be absorbed reliably.
Will missing one dose stop my weight loss?
A single missed dose, managed correctly, is unlikely to affect your overall progress. It's repeated or prolonged gaps that reduce effectiveness.
Can I change my Wegovy injection day?
Yes, as long as there are at least 3 days (more than 72 hours) between doses. Once you've picked a new day, keep to it every week.
