Treatment with the Wegovy pill starts at 1.5 mg once daily. Your endocrinologist can increase the dose to 4 mg, 9 mg and 25 mg, with at least a month at each step. Each tablet is swallowed on an empty stomach with up to half a cup of plain water, at least 30 minutes before food, drinks or other medications. The product information advises skipping a missed dose and taking the next tablet the following day.
- UAE pharmacies list all four Wegovy pill strengths: 1.5 mg, 4 mg, 9 mg and 25 mg.
- The US prescribing information sets the earliest timing for each step: 4 mg from day 31, 9 mg from day 61 and 25 mg from day 91.
- The UK product information states that, if needed, the dose can be kept at the previous level instead of being increased.
- The UK product information recommends taking each tablet after a fasting period of at least eight hours.
- Do not take other oral medications at the same time as the Wegovy pill. Wait at least 30 minutes, unless your clinician advises otherwise.
- Patients taking the 2.4 mg Wegovy injection can move to the 25 mg tablet one week after their last injection, when their endocrinologist agrees that the switch suits them.
- Wegovy pill tablets need no fridge, but they should stay in their original blister pack, away from moisture and light.
01 What are the Wegovy pill doses?
The Wegovy pill (oral semaglutide) comes in four strengths. The US prescribing information for Wegovy sets out the steps and the earliest day each one can begin:
| Step | Dose, once daily | Earliest start | Purpose |
|---|---|---|---|
| First | 1.5 mg | Day 1 | Starting dose |
| Second | 4 mg | Day 31 | Dose increase |
| Third | 9 mg | Day 61 | Dose increase |
| Fourth | 25 mg | Day 91 | Maintenance dose |
The days in the table are the earliest points for each step, not fixed dates. All four strengths are listed at UAE pharmacies, and our page on the Wegovy pill cost in the UAE gives the price of each one.
02 How is the Wegovy pill dose increased?
The UK product information for the Wegovy pill recommends at least one month at each dose before the next increase. The US prescribing information gives 25 mg as the maintenance dose. The UK product information also allows the dose to stay at the previous level if needed.
The lower strengths are steps in the dose escalation, and 25 mg once daily is the recommended maintenance dose. Your endocrinologist will review your dose with you at each monthly follow-up.
If a dose is not well tolerated, the US prescribing information advises considering a delay before the next increase. If the 25 mg dose is not well tolerated, it suggests considering a switch to the 1.7 mg Wegovy injection.
03 How should you take the Wegovy pill?
The UK and US product information set out the same core rules for each tablet:
- An empty stomach, after at least eight hours without food
- Up to half a cup (120 mL) of plain water, and no other drink
- The tablet swallowed whole, never split, crushed or chewed
- No food, drink or other oral medications for at least 30 minutes afterwards
- No more than one tablet in a day
The US prescribing information asks for the tablet to be taken in the morning, while the UK product information does not set a time of day. These rules matter because food and drink reduce how much semaglutide the body absorbs from each tablet.
Our guide to your first weeks on the Wegovy pill explains how to build the morning routine.
04 What to do if you miss a dose of the Wegovy pill
If you miss a dose, both the UK and US product information advise skipping it and taking the next tablet the following day. Two tablets should never be taken together to make up for a missed dose.
Neither document gives a separate rule for several missed doses in a row. If you have missed more than one dose, we recommend contacting your endocrinologist before you continue.
05 Switching from the Wegovy injection to the Wegovy pill
If you take the 2.4 mg Wegovy injection, both documents describe starting the 25 mg tablet one week after your last injection. The US prescribing information also describes the reverse switch, with the 2.4 mg injection starting the day after the last 25 mg tablet.
Our comparison of the Wegovy pill and the Wegovy injection covers the other differences between them. The Wegovy injection dosage guide sets out the weekly doses.
Rybelsus is a separate oral semaglutide licensed for type 2 diabetes, with its own doses.
06 Other medications and the Wegovy pill
We recommend taking your other morning tablets after the 30-minute wait. In a study described in the UK product information, taking five other tablets together with the Wegovy pill reduced semaglutide absorption by around a third.
If you take levothyroxine for an underactive thyroid, tell your endocrinologist. The Wegovy pill increased exposure to levothyroxine by 33% in that study, so your thyroid levels may need checking.
If you take insulin or a sulfonylurea, your endocrinologist may lower the dose of those medications, as the risk of low blood sugar can rise. The product information found no relevant change in the levels of a combined oral contraceptive pill.
07 How should you store the Wegovy pill?
The UK product information recommends keeping the tablets in their original blister pack to protect them from moisture and light. No special temperature storage is needed, so the tablets do not have to be kept in the fridge.
08 Side effects when the Wegovy pill dose increases
Side effects such as nausea or constipation can be particularly pronounced in the first few days at a new dose. They often improve as your body adjusts, although some symptoms last longer. Our page on Wegovy pill side effects lists each one with its rate from the product information.
09 How Endocare manages your Wegovy pill dose
Your endocrinologist will review blood tests from the last three months before prescribing. If your results are out of date, the clinic can arrange the required tests. If they are current, your assessment and prescription can usually be completed at your first appointment.
Your endocrinologist will decide each dose step with you at your monthly follow-up, based on your weight loss, how you tolerate the medication and your body composition results. At Endocare, body composition analysis is included free of charge at every consultation.
Body composition analysis estimates body fat, muscle mass and body water. Repeated measurements help your endocrinologist understand how your body is changing beyond the number on the scale.
10 FAQ
Can I split or crush the Wegovy pill?
No. Both documents ask for the tablet to be swallowed whole, without splitting, crushing or chewing. A different dose comes from a different strength of tablet.
Can I stay on a lower dose of the Wegovy pill?
For some patients, yes. The UK product information allows the dose to be maintained at the previous level if needed, and the US prescribing information allows dose increases to be delayed. Your endocrinologist will discuss the right dose for you.
Can I take two 4 mg tablets instead of one 9 mg tablet?
No. The US prescribing information states that no more than one tablet should be taken in a day. Each dose step uses one tablet of the prescribed strength.
How long does it take to reach the 25 mg dose?
At least three months. The US prescribing information sets day 91 as the earliest start for 25 mg, after a month at each of the three lower doses. Some patients stay longer at a lower dose.
Patients should not decide by themselves to start a GLP-1 medication. A doctor’s review is critical to ensure the treatment is safe and appropriate for the individual.
Your first appointment is a full medical assessment, not simply a prescription visit. Your endocrinologist will review your medical history and any relevant blood tests, assess your weight and metabolic health, and discuss whether the Wegovy pill or another weight loss treatment is the right option for you.
Monthly follow-up appointments can be held in person at the clinic or online. We recommend the first consultation in person, as it includes a physical examination and body composition analysis.
