Take the Wegovy Tablet first thing in the morning on an empty stomach, swallowing it whole with a small sip of plain water (no more). Then wait at least 30 minutes before eating, drinking anything else, or taking any other medicines — taken with food it is far less effective.
The Wegovy Tablet contains oral semaglutide, the same active medicine as the Wegovy injection, taken as a once-daily tablet instead of a weekly injection. Getting the timing right is the single most important thing you can do to help it work.
Why the timing matters so much
Semaglutide is a large molecule that struggles to survive the digestive process on its own. The tablet is formulated to help a small amount of it absorb through the lining of your stomach.
That absorption only happens well when your stomach is genuinely empty and there is very little fluid present. Food, and even too much water, dilute the tablet and dramatically reduce how much medicine reaches your bloodstream. This is why the fasting window is a firm rule, not a suggestion.
Step-by-step: taking your first dose
- Take it first thing in the morning. Do this before you eat or drink anything, ideally as soon as you wake up so the routine becomes automatic.
- Use only a small sip of plain water. No more than roughly half a glass. Do not use tea, coffee, juice, or any other drink.
- Swallow the tablet whole. Do not split, crush, or chew it — this damages the formulation that protects the medicine.
- Take it on its own. Do not take other tablets, supplements, or medicines at the same time.
- Wait at least 30 minutes. During this window, have nothing to eat or drink, and take no other medication. Only after 30 minutes should you have breakfast, other drinks, or your usual tablets.
A simple routine that works
Many people find it easiest to keep the tablet and a small glass of water on their bedside table. Take it the moment you wake, then use the 30-minute wait to shower and get ready before breakfast.
How the dose builds up over time
You do not start on the full dose. The Wegovy Tablet is titrated upwards gradually so your body can adjust and to help limit side effects.
| Step | Dose |
|---|---|
| Starter | 1.5mg |
| Next | 4mg |
| Next | 9mg |
| Maintenance (maximum licensed dose) | 25mg |
Your prescriber will guide when to move up a step. Never increase your dose faster than advised.
What results can I expect?
In the OASIS phase-3 programme, oral semaglutide 25mg produced clinically meaningful weight loss of up to 14%* over around 64 weeks, alongside lifestyle support. Individual results vary; not everyone reaches this.
The tablet works best when combined with sensible eating and activity — the medicine reduces appetite and helps you feel full sooner, but your daily habits still matter.

Common questions about doses and mistakes
What if I forget a dose?
If you miss a dose, skip it entirely and take your next tablet at your usual time the following morning. Do not take two tablets on the same day to catch up.
What if I accidentally eat too soon?
If you eat or drink within the 30-minute window, the tablet may not absorb properly and that dose may work poorly. Do not take a second tablet — simply resume your normal routine the next morning.
Can I take it in the evening instead?
The tablet is designed to be taken on waking after an overnight fast, so the morning is when your stomach is naturally empty. Following the intended routine gives the medicine the best chance to work.
Side effects to be aware of
The Wegovy Tablet has the same GLP-1 class side-effect profile as the injectable medicines. The most common effects (affecting more than 1 in 10 people) include nausea, diarrhoea, constipation, vomiting, decreased appetite, and fatigue. These are often strongest early on and tend to ease as your body adjusts.
Rare but serious effects can include severe allergic reactions, acute pancreatitis, and severe gastrointestinal problems. Seek medical advice promptly if you have severe or persistent symptoms, particularly severe abdominal pain.
You can report any suspected side effect through the MHRA Yellow Card scheme at https://yellowcard.mhra.gov.uk/.
Who can take the Wegovy Tablet?
The Wegovy Tablet is a prescription-only medicine. It may be an option if you are aged 18 or over and have a BMI of 30 or more, or a BMI of 27–30 with a weight-related condition such as type 2 diabetes, high blood pressure, or sleep apnoea.
It is not suitable if you are pregnant, planning pregnancy, or breastfeeding; have type 1 diabetes; have a personal or family history of medullary thyroid carcinoma or MEN2; have a history of pancreatitis or severe gastrointestinal disease; have an active eating disorder; have severe liver or kidney impairment; or are allergic to the active ingredient.
A treatment is prescribed only if clinically appropriate after a free online consultation with a GPhC-registered prescriber. You can begin your free eligibility check at start your consultation.
How it compares with other options
If a daily routine and 30-minute wait do not suit your lifestyle, a weekly injection may fit better. The Wegovy injection and Mounjaro are self-injected once a week, while Foundayo (orforglipron) is an ordinary daily pill that does not require a fasting window — though it is not yet UK-licensed.
