The highest FDA-approved injectable dose of semaglutide in the United States is 7.2 mg once weekly, available as Wegovy HD for certain adults using semaglutide for weight reduction. The highest approved oral dose is 25 mg once daily with Wegovy tablets.
The FDA approved Wegovy HD on March 19, 2026, for long-term weight reduction and weight-loss maintenance in certain adults. Oral and injectable semaglutide doses are not directly comparable because the products use different formulations and absorption routes.
Semaglutide Maximum Doses at a Glance
| Product | Form | Highest labeled dose | Main use |
|---|---|---|---|
| Wegovy HD | Injection | 7.2 mg once weekly | Weight reduction in certain adults |
| Wegovy | Tablet | 25 mg once daily | Weight reduction and cardiovascular risk reduction in adults |
| Wegovy | Injection | 2.4 mg once weekly for most indications; up to 7.2 mg for selected adults using it for weight management | Weight reduction, cardiovascular risk reduction and other approved indications |
| Ozempic | Injection | 2 mg once weekly | Type 2 diabetes |
| Rybelsus | Tablet | 14 mg once daily | Type 2 diabetes |
| Ozempic tablets | Tablet | 9 mg once daily | Type 2 diabetes and cardiovascular risk reduction under current U.S. labeling |
These milligram values should not be compared across products. For example, 25 mg of oral Wegovy is not equivalent to 25 mg of injected semaglutide. Patients should not switch between semaglutide products without instructions from a prescriber.
What Is the Highest Injectable Dose of Semaglutide?
The highest approved injectable dose is Wegovy HD 7.2 mg once weekly.
The 7.2 mg dose is not a starting dose. Adults should first tolerate Wegovy 2.4 mg once weekly for at least four weeks. A prescriber may then increase the dose to 7.2 mg when additional weight reduction is clinically indicated and the patient can tolerate the higher dose.
What Is the Highest Dose of Semaglutide for Ozempic?
The highest labeled dose of Ozempic injection is 2 mg once weekly.
Ozempic is approved for adults with type 2 diabetes. It is not the semaglutide product specifically approved for weight management.
Using more than 2 mg of Ozempic, combining Ozempic with Wegovy or taking another GLP-1 medication does not provide a safe way to reach the Wegovy HD dose. The products have different indications, dosing schedules and delivery systems.
What Is the Highest Oral Dose of Semaglutide?
The highest approved oral dose listed in the current U.S. labeling is Wegovy 25 mg once daily for eligible adults using oral semaglutide for weight reduction or cardiovascular risk reduction.
The Wegovy tablet schedule increases from 1.5 mg to 4 mg, then 9 mg, before reaching the 25 mg maintenance dose.
For diabetes treatment, the maximum labeled doses are:
- Rybelsus: 14 mg once daily
- Ozempic tablets: 9 mg once daily under current U.S. labeling
The Rybelsus instructions state that patients should take the tablet on an empty stomach with a small amount of water. They should then wait at least 30 minutes before eating, drinking other beverages or taking other oral medicines.
Is the Highest Dose Always the Best Dose?
No. The highest dose is not automatically the right dose for every patient.
The appropriate dose depends on the product, treatment goal, response, side effects and medical history. Higher doses can cause more gastrointestinal side effects, including:
- Nausea
- Vomiting
- Diarrhea
- Constipation
- Abdominal pain
The FDA also reported that altered skin sensation, including sensitivity, pain or burning, occurred more often with Wegovy 7.2 mg than with lower doses.
Semaglutide has also been associated with pancreatitis, gallbladder disease, dehydration-related kidney injury and low blood sugar when used with insulin or insulin-releasing medicines. It is contraindicated in people with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2.
Bottom Line
The maximum semaglutide dose depends on the specific product and its approved use. Do not increase a dose, convert milligrams into syringe units or combine semaglutide products without instructions from a licensed prescriber or pharmacist.
