Wegovy Pill Side Effects — What the 25 mg Tablet Label Says

You switched to the pill hoping the queasy days would be gentler than on the shot. Two weeks into a new bottle, you're sitting with a cup of plain water and the same familiar wave of nausea. It's a fair question whether the tablet should feel different. The label has a fairly direct answer.

Are the pill's side effects different from the shot's?

Mostly not. The Wegovy label says that in its tablet trial, the types and frequency of common side effects were similar to those seen with the weekly 2.4 mg injection.

That makes sense, given what the label says about blood levels. In adults without type 2 diabetes, average semaglutide levels on the 25 mg daily tablet were similar to those on the 2.4 mg weekly shot. The medicine in your blood is the same; only the route is different.

For reference, these are the injection figures the label points to, from its 2.4 mg weight-management trials:

Side effect	Placebo	Wegovy 2.4 mg injection
Nausea	16%	44%
Diarrhea	16%	30%
Vomiting	6%	24%
Constipation	11%	24%
Stomach pain	10%	20%
Headache	10%	14%
Fatigue	5%	11%
Indigestion	3%	9%
Dizziness	4%	8%

What did the tablet trial itself show?

The tablet was tested in OASIS 4, a 64-week trial of 307 adults with obesity, or overweight plus a weight-related condition, and without diabetes. The label and the published trial report:

• Stomach-related side effects: 74.0% on the tablet versus 42.2% on placebo.
• Severe stomach side effects: 2% on the tablet versus 0% on placebo.
• Unusual skin sensations (dysesthesia): 5% on the tablet versus 0% on placebo.
• Stopping because of side effects: 6.9% on the tablet versus 5.9% on placebo, with stomach symptoms the most common reason (3.4% versus 2%).

It was a small trial compared with the injection studies, which is one reason the label leans on the injection data for the wider picture.

When are stomach symptoms most likely?

For Wegovy overall, the label ties stomach side effects to dose escalation, which is why the tablet climbs slowly: 1.5 mg, 4 mg and 9 mg, each for 30 days, then 25 mg. The first days of a new strength are the ones worth watching.

The pill adds one variable the shot doesn't have: time of day. You take it first thing, on an empty stomach, and wait at least 30 minutes before eating. If nausea tends to land mid-morning, a log will show it, and that's useful detail for your prescriber.

What is dysesthesia?

It's an umbrella term for changed skin sensations: tingling, burning, sensitivity or skin that hurts to the touch. The label says it became more common with higher doses and higher blood levels of semaglutide. It's not dangerous in itself, but it's real and worth reporting.

Which serious risks does the label warn about?

The label says the injection's less common side effects apply to the tablet too. Its warnings include:

• Acute pancreatitis.
• Gallbladder problems, including gallstones.
• Kidney injury from dehydration, usually after vomiting or diarrhea.
• Severe stomach reactions; Wegovy isn't recommended with severe gastroparesis.
• Serious allergic reactions.
• A raised heart rate.
• Low blood sugar, mainly with insulin or a sulfonylurea.
• Breathing in stomach contents under anesthesia — tell anyone planning a procedure.

There's also a boxed warning about thyroid C-cell tumors in rodents; it's unknown whether this applies to people. Wegovy isn't for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2.

What we'd track

For side effects on a daily tablet, these are the notes we'd keep:

1. Tablet time and first meal time. It helps you see whether symptoms follow the morning routine.
2. A daily stomach rating. Nausea, constipation and reflux on a simple scale show whether things settle within each 30-day step.
3. Skin sensations, with the date they began. Useful context next to your dose step.
4. Water. Dehydration links several of the label's serious warnings.
5. Your current strength and day count. So every symptom has a dose next to it.

Holt logs daily pills as well as weekly shots, with severity sliders for nausea, constipation, heartburn and fatigue lined up against your dose days, a water count, and a doctor-visit report for your next appointment. It's free to download, with an optional subscription.
