Semaglutide Dosage: Approved Schedules, Charts, and Safety

Semaglutide dosage depends on which product is being used and what it is treating. Wegovy, the version approved for weight loss, starts at 0.25 mg once weekly and reaches a maximum of 2.4 mg once weekly. Ozempic for type 2 diabetes also begins at 0.25 mg weekly but tops out at 2 mg, while Rybelsus tablets start at 3 mg once daily and go up to 14 mg daily.

Semaglutide Dosing at a Glance

Three brand-name medications contain semaglutide, and no two share the same schedule. The table below lists the FDA-approved starting dose, titration steps, and maximum dose for each product.

Product	Form	Starting Dose	Titration	Maximum Dose	Approved Use
Wegovy	Weekly injection	0.25 mg	0.5, 1, 1.7, 2.4 mg every 4 weeks	2.4 mg weekly	Chronic weight management
Ozempic	Weekly injection	0.25 mg	0.5, 1, then 2 mg	2 mg weekly	Type 2 diabetes
Rybelsus	Daily tablet	3 mg	7 mg, then 14 mg	14 mg daily	Type 2 diabetes

Every product uses a step-up approach called titration. Titration allows the body to adjust to the medication and reduces nausea and other gastrointestinal side effects. Nobody should jump straight to a maintenance dose on day one.

Semaglutide Weight Loss Dosage Chart

Wegovy is the only semaglutide injection approved by the FDA for chronic weight management, and its full schedule takes about four months to complete. The semaglutide dosage for weight loss rises in five steps, with at least four weeks between each one.

Weeks	Weekly Dose
1 to 4	0.25 mg
5 to 8	0.5 mg
9 to 12	1 mg
13 to 16	1.7 mg
17 and beyond	2.4 mg

The 0.25 mg, 0.5 mg, and 1 mg steps are titration doses rather than weight-loss doses. Wegovy's maximum dose is 2.4 mg once weekly, and that is the level most people stay on long term.

A weekly dose of semaglutide 1 mg is a common maintenance level for type 2 diabetes, but in weight loss treatment it is usually just a temporary step on the way to 1.7 mg or 2.4 mg. People who cannot tolerate 2.4 mg may stay at 1.7 mg, which still produced meaningful weight loss in clinical trials.

Semaglutide Injection Dose vs. Oral Tablets

Injections and tablets are not interchangeable. Injectable semaglutide is measured in milligrams per week, while oral semaglutide is measured in milligrams per day, and the two forms are absorbed quite differently.

Rybelsus Tablet Dosing

Rybelsus follows a three-step schedule: 3 mg once daily for 30 days, then 7 mg once daily, then 14 mg once daily if blood sugar needs more control. That 3 mg starting dose is only a tolerance step and is not considered an effective dose for blood sugar.

Rybelsus must be taken on an empty stomach with no more than 4 ounces of plain water, and nothing else should be eaten or drunk for at least 30 minutes afterward. Taking the tablet with food sharply reduces how much semaglutide the body absorbs.

As of this writing, Rybelsus is approved only for type 2 diabetes, so there is no FDA-approved semaglutide tablet dose for weight loss. Oral products sold for weight loss outside a prescription are either compounded, unregulated, or part of a clinical trial.

Compounded Semaglutide and Other Forms

Compounded semaglutide is not FDA-approved, and there is no standard dosage chart for it. Compounding pharmacies set their own concentrations, so the correct amount depends entirely on the vial label and the prescriber's instructions.

• Vials labeled 5 mg/mL: A 0.25 mg dose equals 0.05 mL, or 5 units on a U-100 insulin syringe. That math is why so many people search for a semaglutide 5mg/ml dosage chart.
• Vials labeled 10 mg/mL: The same doses take half the volume, so 0.25 mg becomes 2.5 units and 1 mg becomes 10 units. Concentration, not vial size, decides the number on the syringe.
• Blends with L-carnitine or vitamin B12: Added ingredients change the concentration again, so the units will not match a plain semaglutide chart.
• Sublingual drops and tablets: There is no standard sublingual semaglutide dosage chart because these products are not FDA-approved and absorption under the tongue has not been established.

Compounded semaglutide dosage should always come from the prescriber who wrote the prescription, never from a friend's schedule or a social media post. Cagrilintide semaglutide dosage information comes only from clinical trials, since that combination is still investigational and no approved product exists yet.

How Semaglutide Dosing Compares to Tirzepatide

Tirzepatide is a different medication, so its milligrams do not translate into semaglutide milligrams. The table below shows how each drug is titrated on its own terms.

Drug	Starting Weekly Dose	Increase Interval	Maximum Weekly Dose
Wegovy (semaglutide)	0.25 mg	Every 4 weeks	2.4 mg
Ozempic (semaglutide)	0.25 mg	Every 4 weeks	2 mg
Zepbound (tirzepatide)	2.5 mg	Every 4 weeks	15 mg
Mounjaro (tirzepatide)	2.5 mg	Every 4 weeks	15 mg

Anyone comparing tirzepatide vs semaglutide dosage for weight loss should compare each drug's own titration schedule instead of the numbers side by side. Semaglutide is a GLP-1 receptor agonist, while tirzepatide acts on both GLP-1 and GIP receptors, which is why the maximum doses look so different.

Titration, Side Effects, and Safety

• Follow the exact schedule from the prescriber, and expect dose increases no more often than every four weeks.
• Common side effects include nausea, vomiting, diarrhea, constipation, and abdominal pain, and they are most noticeable right after a dose increase.
• Semaglutide carries a boxed warning about thyroid C-cell tumors and is not for people with a personal or family history of medullary thyroid cancer or MEN2.
• Semaglutide is not recommended during pregnancy, so anyone planning a pregnancy should talk with a prescriber about stopping it.
• Anyone drawing from a vial should double-check the syringe units against the prescribed dose before every injection.

Semaglutide is a prescription medication, and dosing decisions belong with a licensed healthcare professional who knows the person's medical history, kidney function, and other medications. This article is general information and is not medical advice.

COMMON QUESTIONS

Frequently Asked Questions

What is the starting dose of semaglutide?

The starting dose is 0.25 mg once weekly for injectable semaglutide and 3 mg once daily for Rybelsus tablets. These starter doses exist to help the body adjust and are not the levels that produce the full effect. Prescribers usually raise the injection dose after four weeks and the tablet dose after 30 days.

What is the maximum dose of semaglutide for weight loss?

Wegovy's maximum approved dose is 2.4 mg once weekly, reached after about 16 weeks of titration. Ozempic tops out at 2 mg weekly and Rybelsus at 14 mg daily, but neither of those is approved for weight loss. Higher oral doses have been studied, so people should ask their prescriber what applies to their situation.

Can non-diabetics take semaglutide for weight loss?

Yes. Wegovy is FDA-approved for weight loss in adults who have obesity or who are overweight with at least one related health condition, and a diabetes diagnosis is not required. Ozempic and Rybelsus are approved only for type 2 diabetes, though some prescribers use them off-label. The titration schedule for semaglutide for weight loss in non diabetics dosage terms is the same one used in people with diabetes.
