Oral semaglutide: Rybelsus and Wegovy tablet doses and how to take them

Semaglutide tablets only work well if you take them the label's way: empty stomach, a little water, then 30 minutes before anything else. The doses differ by brand and country.

[00] Short answer

  1. Take one semaglutide tablet each morning on an empty stomach with up to 4 ounces of plain water, then wait at least 30 minutes before food, drinks or other pills1–2.
  2. US Rybelsus: 3 mg for 30 days, then 7 mg, with 14 mg if more blood sugar control is needed1.
  3. Wegovy tablets: 1.5, 4 and 9 mg for 30 days each, then 25 mg a day from day 91. FDA approved them on December 22, 20252–3.
  4. UK Rybelsus comes as 1.5, 4 and 9 mg tablets. The UK label asks for an 8-hour fast and up to 120 mL of water4.
  5. Missed a tablet? Skip it and take the next one the following day. Never take two in one day1–2,4–5.

How do you take Rybelsus or Wegovy tablets?

Take one semaglutide tablet in the morning on an empty stomach, with no more than 4 ounces of plain water. Swallow it whole, then wait at least 30 minutes before you eat, drink anything else or take other pills1–2. The same rules apply to Rybelsus, Ozempic tablets and Wegovy tablets.

  1. Empty stomach, first thing
    Take it in the morning before food. The UK SmPCs say after a fast of at least 8 hours, so overnight4–5.
  2. Plain water only, a little
    Up to 4 ounces of water in the US. The UK says a sip, up to half a glass (120 mL). No coffee, tea or juice to take it with1–2,4.
  3. Swallow it whole
    Don't split, crush, chew or dissolve it1–2.
  4. Wait 30 minutes
    Nothing to eat or drink, and no other tablets, for at least 30 minutes1–2.

The reason is absorption. Semaglutide tablets are absorbed mainly in the stomach, and very little of each dose gets into the blood: about 0.4% to 1% for Rybelsus1. In label studies, more semaglutide was absorbed with 50 mL of water than with 240 mL, and more with a longer wait after the dose1. The UK SmPC says waiting less than 30 minutes lowers absorption4.

What is the Rybelsus dose schedule in the US?

In the US, Rybelsus starts at 3 mg once a day for 30 days, then goes to 7 mg. From day 61, it stays at 7 mg or goes to 14 mg if more blood sugar control is needed1. The 3 mg starting dose is only to help your stomach adjust. It isn't meant to control blood sugar1.

Rybelsus now shares its US label with Ozempic tablets, a second tablet with different strengths: 1.5 mg, then 4 mg, then 9 mg if needed1. The two aren't swapped mg for mg. The label pairs Rybelsus 7 mg with Ozempic tablets 4 mg, and 14 mg with 9 mg, and says not to switch during the first 30 days1.

Both are approved for type 2 diabetes in adults, and to lower heart attack and stroke risk in adults with type 2 diabetes at high risk1.

Semaglutide tablet doses by brand and country

Every semaglutide tablet starts low for about a month and steps up. Wegovy tablets go highest, to 25 mg a day, because they're for weight management rather than diabetes2,5.

Once-daily semaglutide tablets: label dose steps (US prescribing information; UK SmPC section 4.2)
TabletMonth 1Month 2Month 3From month 4Used for
Rybelsus (US)3 mg7 mg7 mg or 14 mg7 mg or 14 mgType 2 diabetes1

Wegovy tablets (US)1.5 mg4 mg9 mg25 mgWeight reduction and heart risk in adults2
Wegovy tablets (UK)1.5 mg4 mg9 mg25 mgWeight management in adults5

US labels count steps in 30-day blocks (days 1 to 30, 31 to 60 and so on). UK labels say at least 1 month at each dose, and the UK Wegovy SmPC allows staying at the previous dose if needed1–2,4–5.

Is there a Wegovy pill?

Yes. FDA approved Wegovy (semaglutide) tablets on December 22, 2025, in 1.5 mg, 4 mg, 9 mg and 25 mg strengths3. The US label starts at 1.5 mg a day and steps up every 30 days to 25 mg a day from day 912.

  • Who they're for (US): adults with obesity, or with overweight and at least one weight-related condition, and adults with heart disease and obesity or overweight, to lower the risk of heart attack, stroke and heart-related death2. Wegovy injection is also approved for teens 12 and older; the tablets are adults only2.
  • If a step isn't tolerated: the label says the prescriber can consider delaying the next step. If 25 mg isn't tolerated, it suggests considering a switch to Wegovy injection 1.7 mg weekly2.
  • Switching from the injection: people on Wegovy 2.4 mg injection can start 25 mg tablets one week after their last injection. Going the other way, start the 2.4 mg injection the day after the last 25 mg tablet2.

In the UK, Wegovy tablets were first authorised on 11 June 2026, for adults with a BMI of 30 or more, or 27 to under 30 with at least one weight-related condition5. For the weekly injection doses, see the semaglutide dosage chart.

Why is UK Rybelsus 1.5 mg, 4 mg and 9 mg?

The UK now uses the newer round Rybelsus tablets: 1.5 mg to start, then 4 mg, with 9 mg as the maximum4. The UK medicines list (eMC) marks the older 3 mg, 7 mg and 14 mg tablets as discontinued6.

The UK SmPC says the two tablet types work the same at these matched doses:

Equal-effect doses of the two semaglutide tablet formulations (UK Rybelsus SmPC, section 5.2, Table 9)
StageRound tablet (current UK)Oval tablet (older)
Starting dose1.5 mg3 mg
Maintenance4 mg7 mg
Maintenance9 mg14 mg

Source: UK SmPC4. The US label uses the same pairings between Rybelsus and Ozempic tablets1.

The UK SmPC also says the effect of switching between semaglutide tablets and injections is hard to predict, because absorption from tablets varies so much. It says 9 mg a day by mouth gives exposure comparable to a 0.5 mg weekly injection4.

Missed a semaglutide tablet, and how to store them

If you miss a Rybelsus, Ozempic or Wegovy tablet, skip it and take the next one the following day. The labels say never to take more than one tablet a day1–2,4–5.

  • US: store at 20°C to 25°C (68°F to 77°F), with short spells at 15°C to 30°C (59°F to 86°F) allowed. Keep the tablets in the original bottle to protect them from moisture1–2.
  • UK: no special temperature is needed. Keep them in the original blister pack to protect from light and moisture4–5.

Semaglutide has a half-life of about one week, and stays in the blood for about 5 weeks after the last tablet1.

Thinking about a daily pill you can take with food? Foundayo (orforglipron) is a different GLP-1 tablet with no fasting rule.

Questions

Can I drink coffee after taking Rybelsus?

Not for at least 30 minutes. The labels say to take the tablet with plain water only, up to 4 ounces, and wait at least 30 minutes before eating, drinking anything else or taking other pills.

What happens if I eat too soon after my semaglutide tablet?

Less semaglutide gets absorbed. The UK SmPC says waiting less than 30 minutes decreases absorption, and the US label reports higher absorption with a longer wait after the dose.

Is Rybelsus the same as Wegovy tablets?

Both are semaglutide taken once a day the same way, but they're different products. Rybelsus is for type 2 diabetes and goes up to 14 mg in the US (9 mg in the UK). Wegovy tablets are for weight management and go up to 25 mg.

Can I take 2 Rybelsus 7 mg tablets instead of one 14 mg?

No. The labels say to take only one tablet a day. The UK SmPC says not to take more than one tablet to get the effect of a higher dose.

Is the Wegovy pill available in the UK?

It's authorised. The UK SmPC for Wegovy tablets gives a first authorisation date of 11 June 2026, with the same 1.5, 4, 9 and 25 mg steps as the US.

How do I switch from Wegovy injections to tablets?

The US label says people on the 2.4 mg weekly injection can start 25 mg tablets one week after their last injection. The UK SmPC says the same. Your prescriber decides whether to switch.
