Missed a Foundayo dose? What to do
The short answer: take it the same day if you remember, skip it if a whole day has gone, and never take two in one day. Here is the detail, including what to do after several missed days.

Missed dose rules at a glance
- Same day: take it as soon as you remember.1
- A full day has passed: skip it, resume your normal schedule.
- Never take more than one tablet in a single day.1
- Several days missed: contact your prescriber before restarting.
- Foundayo has no food or water rules, so you can take a late dose whenever you remember.2
If you remember the same day
Take it. This is the easy scenario, and it is where Foundayo's design genuinely helps: because there are no food, drink or timing restrictions, a tablet remembered at 9pm is just as valid as one taken at 8am.2 There is no window to miss and no empty-stomach rule to work around, unlike the Wegovy oral tablet, as covered in our comparison.
If a whole day has gone by
Skip the missed tablet entirely and carry on with your next scheduled dose. Do not take yesterday's and today's together to level up. Taking two tablets in a day does not recover lost ground; it simply doubles your exposure in 24 hours, which is precisely how people give themselves a rough day of nausea and vomiting for nothing.1
If you have missed several days
Contact your prescriber before restarting. This matters more than people expect. Tolerance to GLP-1 medicines fades with a break, so resuming at your previous dose after a gap can hit considerably harder than it did before. Your prescriber may want you to restart at a lower step and climb again, which is a normal, sensible adjustment rather than lost progress.
The same logic applies if you ran out of supply, were unwell, or paused treatment for any other reason. Restarting is a planned conversation, never a guess.
The one rule with no exceptions
One tablet per day, maximum. Not two after a missed dose, not an extra one before a holiday, not a "boost" when a plateau appears. If your dose no longer feels effective, that is a prescriber conversation, and the dose ladder exists precisely for that.
How to stop missing them
- Anchor the tablet to something you already do without fail: brushing your teeth, the kettle going on, putting the alarm on at night.
- Set a daily phone alarm. Unglamorous and effective, and worth keeping even once the habit is solid.
- Keep the pack visible but away from heat, damp and children. Storage detail is in our storage guide.
- Use a pill organiser if you take other medicines, so a glance tells you whether today's is done.
- Order your repeat early. Running out is the most common cause of a multi-day gap, and it is entirely preventable.
- Travelling? Time zones, spare supply and hand luggage are covered in our travel guide.
Does one missed dose undo your progress?
No. A single missed tablet is a blip, not a setback, and it is not worth the anxiety people attach to it. What matters for results is consistency over months, and the trial outcomes were measured over 72 weeks of ordinary human adherence, missed days included.3 You may notice appetite returning slightly sooner than usual, and it settles once you are back on schedule. Repeated gaps are a different matter: if you are missing doses often, tell your prescriber, because the reason usually has a fix.
