The Wegovy pill is a once-daily oral semaglutide tablet, made by Novo Nordisk, that the FDA label lists for adults to reduce excess body weight and keep it off (with obesity, or overweight plus at least one weight-related condition) and to lower the risk of major cardiovascular events in adults with established cardiovascular disease and obesity or overweight. You take one 25 mg tablet each morning on an empty stomach after a stepped-up start. In the label’s 64-week trial, average weight change was -13.6% versus -2.4% on placebo (Wegovy prescribing information, sections 1 and 14.2).
Wegovy pill vs Rybelsus vs Wegovy injection
All three contain semaglutide but are approved for different uses and are not interchangeable mg for mg.
| Wegovy tablet | Wegovy injection | Rybelsus tablet | |
|---|---|---|---|
| Approved use | Weight reduction and cardiovascular risk reduction in adults | Weight reduction (adults and ages 12+ with obesity), cardiovascular risk reduction, MASH with liver fibrosis in adults | Type 2 diabetes: blood sugar control; cardiovascular risk reduction |
| Schedule | Daily | Weekly | Daily |
| Maintenance dose | 25 mg | 1.7 mg or 2.4 mg (higher dose of 7.2 mg for some adults) | 7 mg or 14 mg (Ozempic tablets: 4 mg or 9 mg) |
| Maker | Novo Nordisk | Novo Nordisk | Novo Nordisk |

How the tablet works
Semaglutide is a GLP-1 receptor agonist: it mimics the gut hormone that supports insulin release after meals, slows stomach emptying and acts on appetite signals, so many people feel full sooner. The tablet form needs strict timing because absorption depends on taking it fasting with a small amount of water.
How to take the Wegovy pill
According to the label (section 2.1):
- Take one tablet once daily, in the morning, on an empty stomach, with up to 4 ounces of plain water and no other liquid.
- Swallow it whole. Do not split, crush, chew or dissolve it.
- Wait at least 30 minutes before eating, drinking or taking other oral medicines.
- Do not take more than one tablet per day.
- If you miss a dose, skip it and take the next one the following day.
The dose steps up every 30 days to reduce stomach side effects (section 2.3):
| Days | Daily dose |
|---|---|
| 1 to 30 | 1.5 mg |
| 31 to 60 | 4 mg |
| 61 to 90 | 9 mg |
| 91 onward | 25 mg (maintenance) |
If 25 mg is not tolerated, the label suggests considering the 1.7 mg weekly injection. Your prescriber decides the plan; do not adjust it yourself, and take it with a reduced-calorie diet and more physical activity as the label directs.
What the trial showed
In the label’s Study 7 (64 weeks, adults with obesity or overweight and at least one comorbidity, without type 2 diabetes), average weight change from baseline was -13.6% with the 25 mg tablet and -2.4% with placebo. At least 5% weight loss was reached by 76.3% of people on the tablet versus 31.3% on placebo, and at least 20% by 27.9% versus 3.1% (Table 11). The same study is published as OASIS 4 (NEJM, 2025). These are averages from a controlled trial that included lifestyle counseling, so individual results vary. For comparison, the injection’s trials are in the semaglutide guide.
Side effects
In the tablet trial, 6.9% of people on the tablet and 5.9% on placebo stopped treatment because of adverse reactions, and gastrointestinal reactions were the most common reason (3.4% vs 2%). The label says the types and frequencies of common reactions were similar to those seen with the injection: for the 2.4 mg injection, nausea (44% vs 16% placebo), diarrhea (30% vs 16%), vomiting (24% vs 6%), constipation (24% vs 11%) and abdominal pain (20% vs 10%). Gallstones (cholelithiasis) were reported in 2.5% of tablet-treated adults vs 1% on placebo.
The label also has a boxed warning about thyroid C-cell tumors seen in rodents, and warns about pancreatitis, low blood sugar with insulin or sulfonylureas, kidney injury from dehydration, severe gastrointestinal reactions, increased heart rate, allergic reactions, diabetic retinopathy complications and aspiration during anesthesia. It is contraindicated with a personal or family history of medullary thyroid carcinoma or MEN 2. The label also says to stop semaglutide products in women at least 2 months before a planned pregnancy.

Who is it for
Per the label, adults with obesity, or with overweight and at least one weight-related comorbid condition (for weight reduction), and adults with established cardiovascular disease plus obesity or overweight (for cardiovascular risk reduction). It should not be combined with other semaglutide products or other GLP-1 receptor agonists. Only a prescriber can decide whether it fits you. If you buy from anywhere other than a licensed pharmacy, note the FDA’s warning that unapproved versions are not reviewed for safety, effectiveness and quality (FDA).
Tracking a daily pill
A morning routine only works if you can see it. Useful things to log:
- Whether you took the tablet and when, and the 30-minute wait
- Missed doses
- Side effects and their timing
- Meals, protein and water
- Weekly weight
Mingo is a GLP-1 tracker for iPhone and Android that logs shots and doses, food and protein, side effects and weight in one place; it doesn’t replace your doctor. Get the app.

Frequently asked questions
What is the Wegovy pill used for?
Adults can use it, with a reduced-calorie diet and more physical activity, to reduce excess body weight and maintain the loss (obesity, or overweight with a weight-related condition) and to reduce major cardiovascular event risk if they have established cardiovascular disease and obesity or overweight.
How do I take the Wegovy pill?
Once daily in the morning, on an empty stomach, with up to 4 ounces of plain water, swallowed whole. Wait at least 30 minutes before eating, drinking or taking other oral medicines. If you miss a dose, skip it and take the next dose the next day.
What are Wegovy pill side effects?
Gastrointestinal effects such as nausea, diarrhea, vomiting and constipation are the most common, along with abdominal pain. Gallstones and pancreatitis are less common but serious. Tell your prescriber about severe or lasting symptoms.
How soon can I see results?
The dose is raised every 30 days and the label’s trial measured results at 64 weeks, so change is gradual and differs between people. Your prescriber can review progress with you.
Is the Wegovy pill the same as Rybelsus?
No. Both contain semaglutide, but Rybelsus is approved for type 2 diabetes and Wegovy tablets for weight reduction and cardiovascular risk reduction, with different strengths. They are not substitutable mg for mg. In the US, Rybelsus is being replaced by Ozempic tablets, which are also for type 2 diabetes.
