Ozempic Dosage Chart for Weight Loss

The standard Ozempic dosage schedule starts low and increases slowly: 0.25 mg once weekly for the first 4 weeks, then 0.5 mg once weekly, then up to 1 mg and a maximum of 2 mg once weekly if more effect is needed and tolerated. This Ozempic dosage chart reflects the titration steps in the FDA prescribing information and is shared for education only. It is not a prescription, and only a clinician can set or change your dose.

Ozempic is a brand name for semaglutide, a once-weekly injection you give yourself under the skin. It is FDA-approved to treat type 2 diabetes, and it is often used off-label for weight loss. The semaglutide product that is actually approved for weight management is Wegovy, which is the same drug at different doses. If you want to understand how the medicine reduces appetite in the first place, see how semaglutide works for weight loss.

Because Ozempic is a diabetes medicine being used off-label for weight, the dose schedule below is drawn from the FDA prescribing information for its approved use. A prescriber applies clinical judgment to the individual in front of them, so your real-world plan may look slightly different. Think of this Ozempic dosage chart as the common starting point that a clinician then tailors, not a fixed set of rules you follow on your own.

The Ozempic dosage chart, week by week

The reason for a gradual increase is simple: starting at a full dose causes far more nausea and other stomach side effects. The slow ramp lets your body adjust. The 0.25 mg starting dose is a starter dose only, meant to reduce side effects. It is not considered a therapeutic or maintenance dose, so almost everyone moves past it.

Weeks	Weekly dose	Purpose
Weeks 1 to 4	0.25 mg once weekly	Starter dose to reduce side effects. Not a treatment dose.
Weeks 5 to 8	0.5 mg once weekly	First treatment dose. Many people do well here.
Week 9 onward	1 mg once weekly	Increase only if more effect is needed and tolerated.
Later, if needed	2 mg once weekly (maximum)	Highest approved Ozempic dose, reached after 1 mg.

Each step up happens only after you have spent at least 4 weeks at your current dose. Available pen strengths are 0.25 mg, 0.5 mg, 1 mg, and 2 mg. A clinician decides whether and when to move you to the next step based on how you feel and how your body is responding.

Why the Ozempic dosage climbs so slowly

The whole titration exists to reduce gastrointestinal side effects, especially nausea. Going up too fast is the single most common reason people feel unwell early on. If a dose is not tolerated, a clinician may keep you at your current dose longer before increasing, or hold off entirely. This is normal and safe. What is not safe is speeding up the schedule on your own.

Nausea, when it happens, tends to be worst in the days after a dose increase and then eases. For practical relief strategies, see managing nausea on GLP-1 medications, and for a fuller picture of what to expect and when, read our guides to Ozempic side effects and the GLP-1 side effects timeline.

How high does the Ozempic dose need to go?

Higher doses tend to produce more blood-sugar and weight effect, but the right maintenance dose is individual. Many people do well at 0.5 mg or 1 mg and never need to reach 2 mg. There is no rule that says everyone must climb to the maximum. The goal is the lowest dose that gives you a good result with side effects you can live with.

This is why the schedule is written with the word "if" at each step. Moving from 0.5 mg to 1 mg, or from 1 mg to 2 mg, is a decision your clinician makes based on your response and how well you are tolerating the current dose. Some people settle at 0.5 mg and stay there for the long term. Others need to build higher. Neither path is a failure, and there is no benefit to rushing toward the top of the chart just because a higher number exists.

It is worth knowing that Ozempic's maximum of 2 mg once weekly is lower than Wegovy's maintenance dose of 2.4 mg once weekly. That difference is one reason Wegovy, not Ozempic, is the semaglutide product labeled for weight loss. If you are comparing the two, our Ozempic vs Wegovy comparison breaks down the dosing and approval differences, and you can see where both sit among FDA-approved GLP-1 medications.

When you might see weight results

Because the dose builds up over weeks, the effect on appetite and weight also builds gradually. Do not expect the starter dose to do the heavy lifting. Meaningful appetite changes usually track with reaching the treatment doses. Our GLP-1 weight loss timeline walks through what a realistic month-by-month picture looks like, and the semaglutide dosing schedule covers the same titration in more detail.

A common point of confusion is comparing your progress to someone else's dose. Two people can be on the same 1 mg dose and respond quite differently, and the same person can respond differently at two points in time. The dose on the chart is not a promise of a specific result, and it is not a race. What matters is a steady, sustainable approach that your prescriber is monitoring, rather than chasing a number you saw someone else mention online.

Safety: this Ozempic dosage chart is not medical advice

This chart shows the standard titration from FDA labeling. It is educational and is not a substitute for a conversation with your own prescriber. Please keep these rules in mind:

• Do not change, skip, or double your dose on your own. If you miss a dose, follow the specific instructions your clinician or pharmacist gave you rather than guessing.
• Do not speed up the schedule to lose weight faster. Faster is not better and mostly means more side effects.
• Your dose is personal. The number that is right for you may differ from this chart, and your clinician sets and adjusts it.
• Red flag: if side effects are hard to manage, or you have severe or lasting vomiting, stomach pain, signs of dehydration, or anything that worries you, contact your prescriber. Do not self-adjust your dose to solve a side effect.

Used the way it is prescribed, the slow and steady Ozempic titration is what makes the medicine tolerable for most people. The chart is a map of the usual route, not a set of instructions to follow without a clinician.
