If you missed this morning’s Wegovy tablet, skip it and take your next tablet tomorrow morning as usual, on an empty stomach. Do not take two to make up for the one you missed [1, 2]. A single missed day changes very little, because semaglutide stays in your body for weeks rather than hours [1]. Wegovy tablets (oral semaglutide) were licensed by the MHRA on 11 June 2026, the UK’s first weight-loss pill, at a maintenance dose of 25 mg once daily [1, 3].

Most people who miss a tablet reach for one of two fixes: taking it later when they remember, or taking two the next day. Neither is the right move, and the reasons are worth understanding, because they also explain how the medicine works.

Can I take my Wegovy tablet later in the day if I forgot this morning?

Usually not, and this is the point where Wegovy tablets behave differently from most medicines.

A Wegovy tablet is only absorbed if it is taken on an empty stomach. The instruction is to take it first thing after an overnight fast of at least 8 hours, swallow it with a small sip of water of no more than 120 ml, then leave 30 minutes before food, drink or any other tablet [1]. Those conditions are what let the medicine reach your bloodstream at all.

Food interrupts the way the tablet is absorbed, so a tablet taken with or soon after a meal delivers very little of its dose [1, 4]. The reason lies in an absorption enhancer called SNAC, explained in full in how do Wegovy tablets survive the stomach?.

So the answer depends on whether you have eaten. If you have already had breakfast or a coffee, taking the tablet now would mean swallowing a dose that mostly cannot be absorbed, and you are better skipping the day. If you are still fasted and it is not much past your usual time, you can take it now and start the 30-minute wait from here.

What happens in your body when you miss one tablet?

Very little. The worry that one forgotten day undoes weeks of effort is common, and it is not what the medicine actually does.

Semaglutide has a half-life of about one week. In the manufacturer’s words, “the half-life of semaglutide is approximately 1 week,” and it “will be present in the circulation for approximately 5 to 7 weeks after the last dose” [1]. By the time you are taking it daily, there is a steady amount of medicine already in your system, and each tablet adds a top-up rather than supplying the whole of the day’s effect on its own. Your appetite is being held by the semaglutide already circulating, not by the single tablet you forgot, so skipping one day does not set back your progress.

Should you take two tablets the next day to catch up?

No, you should not. Take your normal single tablet the next morning and leave the missed one behind.

Doubling up recovers almost nothing, because the level in your body was only ever going to shift slightly. What it can do is bring on nausea. The gut-related side effects of these medicines rise when the amount of medicine climbs quickly, which is the reason the dose is increased in slow monthly steps in the first place [5, 6]. Taking two tablets pushes the level up in a single day, the one thing the gradual schedule is designed to avoid. The official guidance is the same: “if a dose is missed, the missed dose should be skipped, and the next dose should be taken the following day” [1].

What if I have missed several days in a row?

A run of missed days is worth a conversation with your prescriber, mainly so you restart in the right way rather than because harm has been done.

Two things are useful to know. Because semaglutide lingers for 5 to 7 weeks, a few missed days still leaves a meaningful amount in your system, so you are not starting from nothing [1]. But if the gap has been long enough for your tolerance to slip, going straight back to a high dose can bring back the early nausea, since that settling-in effect depends on taking the medicine steadily as the dose was built up [5, 6].

The patient leaflet is direct that you should “not stop using this medicine without talking to your doctor” [2]. If you have missed more than a few days, or you have run out and there has been a gap, speak to your prescriber before restarting. They can tell you which strength to resume at rather than leaving you to guess, and the full schedule from 1.5 mg to 25 mg is set out in Wegovy tablets dosage.

From the clinic

By Ali Salih, Pharmacist Independent Prescriber (GPhC-registered)

If you have already had your coffee before you remembered the tablet.

Skip the day. That instruction sounds wasteful so it is worth explaining the reason behind it. This tablet cannot be absorbed the way most medicines are. Semaglutide is a large and fragile molecule and the stomach would break it down long before it reached the bloodstream. To get around that the tablet carries a protective compound that shields it just long enough to cross the stomach lining directly. That process depends on a fairly narrow set of conditions: an empty stomach, a small amount of plain water, and nothing else for the following half hour. Once food or drink has arrived those conditions no longer apply and a tablet taken at that point will deliver very little of its dose. Waiting until tomorrow morning is not a lost day in any meaningful sense.

If you are worried that one missed morning has undone your progress.

It is very unlikely to have done so and the reason is worth understanding because it corrects a common assumption. Most people imagine the tablet they take each morning is producing that day’s effect. That is not how this medicine works. Semaglutide leaves the body extremely slowly, over weeks rather than hours, so by the time someone is a few weeks into daily dosing there is already a substantial and stable amount of it circulating. Each morning tablet adds a modest top-up to that level rather than supplying the whole of it. A single missed day produces a small and temporary dip. Some people notice their appetite returning more sharply afterwards and reasonably conclude the medicine has stopped working. It has not. That sensation is a proportionate response to a small dip and it settles once the routine resumes.

If you have missed several days and are wondering whether to start again from 1.5 mg.

You almost certainly do not need to restart the full schedule, but it is worth a short conversation with your prescriber before resuming rather than after. The reasoning is simple enough. The dose is raised in slow monthly steps because the body needs time to adjust to each level, and that adjustment is what makes the higher doses tolerable. After a gap of several days some of it will have faded. Returning directly to the previous strength can therefore reproduce the nausea the gradual schedule was designed to avoid. A brief call beforehand is a good deal easier than managing side effects afterwards.

If the tablet seems not to be working and you have not missed a day.

This is the scenario I would want to explore before anything else and it is the one patients rarely raise because they do not recognise it as a problem. A tablet taken with a large glass of water, or folded into an existing routine of morning medications, or taken on a stomach that was less empty than assumed, will absorb poorly. Nothing about the experience feels different. The tablet looked the same and the patient has every reason to believe the dose was taken properly. But the conditions were not met and much of it was wasted. Experience with the diabetes form of oral semaglutide suggests this happens often enough to be worth checking. If someone is on a strength that ought to be reducing appetite noticeably and it is not, the first thing I would ask about is the shape of their morning, before assuming the dose is the problem.

When to check with your prescriber

Most missed doses need nothing more than skipping the day and carrying on as normal. Get in touch with your prescriber if you have missed more than a few days in a row, if a gap has opened up because your prescription ran out, if you are unsure which strength to restart at, or if nausea or vomiting keeps returning when you resume. None of these are emergencies. They are the points where a short conversation keeps your treatment on the right footing.

In short

Miss one Wegovy tablet and there is little to do: skip it, take your next one tomorrow morning on an empty stomach, and do not double up. The medicine’s week-long half-life means a single missed day makes almost no difference to how well it works. Only a longer run of missed days is worth a word with your prescriber, and that is about restarting sensibly. If forgetting is becoming a habit, the daily routine may be the thing to look at, and how to take Wegovy tablets covers what makes it easier to keep to.

Frequently asked questions

I missed my Wegovy tablet this morning. What should I do?

Skip the missed tablet and take your next one tomorrow morning as usual, on an empty stomach [1, 2]. If you have already eaten today, do not take it later, because food stops it being absorbed, and do not take two tablets tomorrow to make up for it.

Can I take my Wegovy tablet at lunchtime if I forgot at breakfast?

You can, but only if you are still fasted. The tablet is absorbed only after an overnight fast, with a small sip of water and a 30-minute wait before anything else [1]. Once you have had food or a coffee, a tablet taken later delivers very little, so it is better to skip the day.

Will missing one dose of Wegovy stop it working or cause weight regain?

No, it will not. Semaglutide stays in your body for around 5 to 7 weeks after the last dose, so one missed day does not meaningfully change the level in your system or set back your progress [1].

What if I have missed Wegovy tablets for several days?

You are not back to the start, because the medicine lingers for weeks, but a longer gap can bring the early side effects back if you return straight to a high dose [1, 5]. Speak to your prescriber before restarting, and do not stop or restart the medicine without that advice [2].

Is the missed-dose rule the same for the Wegovy injection?

No, the rules differ. The injection is weekly rather than daily, so its timing rules are different. If you use the injection, follow the guidance for that form, and is Wegovy a pill or an injection? explains how the two compare.
