# Tracking Rybelsus and the other oral semaglutide tablets

Updated 23 August 2026 · Written by the Penwise team

A tablet is not a smaller injection. Oral semaglutide is taken daily rather than weekly, absorbs only under specific conditions, and now comes in three separate products whose milligram numbers do not mean the same thing. Most trackers were built for a needle and quietly get all of that wrong.

## The fields that do not apply

Half the screen of an injection tracker is meaningless for a tablet. There is no injection site, no pain score, no rotation, no clicks and no pen to discard. Asking for them anyway is how an app tells you it was not built for what you are doing.

In Penwise, oral medication is a route rather than an afterthought. Choosing an oral dose hides the site and pain fields entirely, switches the schedule from weekly to daily, and changes the supply arithmetic to tablets per pack rather than doses per pen. What is left is what actually matters: the dose, the time you took it, and what happened afterwards.

## The fasting window is the thing worth logging

Oral semaglutide is absorbed poorly and inconsistently, which is why the label is unusually specific: take it on an empty stomach after waking, with no more than a small sip of plain water, and wait before eating, drinking anything else or taking other medicines. Get that wrong and the dose you swallowed is not the dose you absorbed.

That makes the time of the tablet genuinely useful data rather than trivia. Penwise records the time you took it, so a run of mornings where the window was rushed is visible instead of forgotten – and a week where the effect seemed weaker has something to be compared against. Confirm the exact instructions for the product you were dispensed with the leaflet or your pharmacist; they vary between products and markets.

## Three ladders, and why the milligrams do not match

This is the part that catches people out, and it is worth spelling out. Oral semaglutide now exists in more than one tablet formulation, and a newer tablet that absorbs better reaches the same exposure at a lower number. A 4 mg tablet on the newer ladder is not a smaller dose than 7 mg on the older one – it is broadly the equivalent one.

| Product | Dose steps offered | Cadence |
| --- | --- | --- |
| Rybelsus (current) | 1.5, 4, 9, 25, 50 mg | Daily |
| Rybelsus 3 / 7 / 14 mg (older) | 3, 7, 14 mg | Daily |
| Wegovy tablets | 1.5, 4, 9, 25 mg | Daily |
| Ozempic tablets | 1.5, 4, 9 mg | Daily |

Packs are 30 tablets, so one pack is a month at one tablet a day. The ladders are not interchangeable milligram for milligram – your prescriber decides the equivalent step.

Penwise keeps these as separate products rather than one list of numbers, so a history that spans a switch stays readable. When you move from an older tablet to a newer one, the change is dated and the doses either side are not silently compared as if they were the same scale.

## Daily means a different relationship with a missed dose

Semaglutide has a half-life of about a week whichever way it enters you, so a single missed tablet is a small dent rather than a cliff. But dailies are missed far more often than weeklies, and a run of missed mornings adds up in a way a single skipped injection does not.

Penwise schedules reminders months ahead at a time you choose, with a follow-up the next day if nothing was logged, and the calendar shows the gaps rather than hiding them. Over a few months, an adherence pattern – always the weekend, always after a late night – is something you can actually see. [Missed GLP-1 doses](https://penwiseapp.com/en/guides/missed-glp-1-dose) covers what the different products mean by “late”.

## Side effects on a daily schedule

On a weekly injection the useful question is which day after the shot a symptom lands. On a daily tablet, the question moves: is it the dose step, the time of day, or the fasting window that changed.

Penwise tracks twenty named side effects on a 0 to 5 scale and nine sliding measures – appetite, fullness, food noise, sweet, salty and fatty cravings, energy, mood and sleep – against the dose you were on that day. Insights only appear when there is enough of your own history to support them, so the app stays quiet rather than guessing. See [the GLP-1 side effect timeline](https://penwiseapp.com/en/guides/glp-1-side-effects-timeline).

## Weight, and the level underneath it

Weight, body fat, lean mass, waist and resting heart rate sit on the same timeline as the dose history, with a goal weight and progress against it. Penwise+ also estimates the semaglutide level from your logged doses, which on a daily schedule shows the climb to a plateau after each step more clearly than a weekly one does. The arithmetic behind it is in [how long semaglutide stays in your system](https://penwiseapp.com/en/guides/how-long-does-ozempic-stay-in-your-system).

## And none of it leaves your phone

No account, no sign-in, no Penwise server holding health data. Everything you log stays in the app on your device, export is free and unlimited, and a backup you export is encrypted on the phone with a passphrase we do not hold.

## Common questions

**Can Penwise track tablets as well as injections?**

Yes. Oral medication is a first-class route. Choosing an oral dose hides the injection site and pain fields, switches the schedule to daily, and counts supply in tablets rather than pen doses.

**Which oral semaglutide products does Penwise know?**

Rybelsus on the current ladder, the older 3 / 7 / 14 mg Rybelsus, Wegovy tablets and Ozempic tablets, each with its own dose steps. They are kept separate because their milligram numbers are not equivalent to each other.

**Is 7 mg of the old Rybelsus the same as 7 mg of the new one?**

No, and that is the point of keeping the ladders apart. A newer tablet formulation absorbs better, so a lower number reaches a similar exposure. Which step replaces which is a decision for your prescriber, not an arithmetic conversion you should do yourself.

**Does Penwise remind me about the fasting window?**

It reminds you to take the dose at the time you set and records the time you logged it. It does not give instructions about how to take your medication – that is on the leaflet and with your prescriber – but having the times recorded is what makes a poor stretch visible afterwards.

**Can I switch from tablets to injections in the same history?**

Yes. Both routes live in one timeline, dated, so a switch is visible rather than a break in the record. The weight and side-effect history carries straight across.

**Is any of this medical advice?**

No. Penwise is a tracking and education tool, not a medical device. It does not diagnose, treat or recommend a dose. Rybelsus, Ozempic and Wegovy are trademarks of Novo Nordisk A/S; Penwise is independent and not affiliated with them.
