Semaglutide Dosage Chart for Weight Loss

If you've been prescribed semaglutide for weight loss, the first questions you probably have are, “how much do I take?” and “how will the dose change over time?”

The good news is that semaglutide follows a simple and structured dosing schedule designed to help your body gradually adjust to it. This article will cover everything you need to know: from your semaglutide starting dose to the maximum dose, how to inject it correctly, and what to do if you miss a dose.

What is semaglutide?

Semaglutide is a medication that mimics the hormone glucagon-like peptide-1 (GLP-1). GLP-1 is a natural hormone produced in your body after you eat. By mimicking GLP-1, semaglutide can help you feel fuller for longer, slow digestion, and reduce appetite, all of which can help reduce caloric intake and promote weight loss.

Semaglutide for weight loss is available in both injectable and oral tablet forms.

The brand names are Wegovy (available as both an injection and an oral tablet, FDA-approved for weight management), Ozempic (an injection, FDA-approved for type 2 diabetes but sometimes prescribed for weight loss), and Rybelsus (a separate oral tablet, FDA-approved for type 2 diabetes). This article focuses on the injectable forms of semaglutide.

“Compounded” semaglutide (a custom-mixed version) is also available, but it’s important to note that compounded semaglutide is not FDA-approved and isn’t the same as Ozempic or Wegovy.

In clinical trials, results have shown that people taking semaglutide lost an average of 15% of their body weight over 68 weeks, a result that has made it one of the most talked-about weight loss medications available.

Semaglutide dosage chart for weight loss

Semaglutide dosing follows a process called dose escalation or titration, which means your dose starts low and increases gradually over time. This gradual increase gives your body a chance to adjust and helps manage any potential side effects.

The table below shows the FDA-approved titration schedule for injectable Wegovy (the brand-name version of semaglutide approved specifically for weight loss):

In March 2026, the FDA approved a higher 7.2mg dose of Wegovy, called Wegovy HD, for adults who tolerated the 2.4mg dose for at least four weeks and need to lose additional weight. This isn't part of the standard titration schedule. It's an optional step-up your healthcare provider may consider if 2.4mg isn't providing enough results.

Your healthcare provider will guide you through this dosing schedule, and depending on how you tolerate the medication, they might choose to keep you at a lower dose for longer before increasing.

What is the max dose of semaglutide for weight loss?

The maximum dose of semaglutide for weight loss is 2.4mg per week for Wegovy, with a higher 7.2mg dose available, or 2mg per week for Ozempic. Most people typically reach their maintenance dose after around 16 weeks.

That said, reaching the maximum dose isn’t always the goal. Your healthcare provider may choose to keep you at a lower maintenance dose if you’re tolerating it well and seeing good results. The aim is to find the lowest effective dose, rather than the highest possible one. 

If you’re taking compounded semaglutide, dosing isn’t necessarily standardized in the same way as the brand-name versions. 

How to take semaglutide for weight loss

Semaglutide for weight loss is given as a subcutaneous injection, meaning it’s injected into fatty tissue just under the skin. You give it to yourself once a week, on the same day each week, with or without food. 

Injection sites

There are three different spots you can use: 

• Your abdomen (around or below your belly button)

• Your upper thigh

• The back of your upper arm

These injection sites should be rotated every week. This gives your skin time to heal, and it’s generally just good practice to avoid injecting in the same spot twice in a row. 

Step-by-step injection instructions

1. Wash your hands with soap and water and dry them well using a clean towel.

2. Double-checks. Check the dosage and expiration date on the pen or vial. The liquid should be clear and colorless. If it looks cloudy, has a weird color, contains particles, or anything else feels off, don’t use it, and contact your healthcare provider.

3. Get your dose ready. For Wegovy, each dose has a prefilled single-dose pen. Simply attach the needle. For Ozempic, attach a new needle and set your prescribed dose. For compounded semaglutide, draw the dose from the vial using a sterile syringe.

4. Clean your skin on the injection site with an alcohol swab and let it dry.

5. Inject at a 90-degree angle firmly into the skin. Press the button or plunger until the full dose is injected, then count a few seconds before pulling out the needle. 

6. Remove the needle and press gently with a gauze pad if there’s blood, but don’t rub it. 

7. Throw away the needle or pen safely in an FDA-cleared sharps container. Never throw away needles in your regular trash.

Last but not least, always follow the specific instructions that come with your medication, as instructions may differ slightly depending on whether you’re using Wegovy, Ozempic, or compounded semaglutide.

How to store semaglutide

Any unopened pens or vials should be stored in the refrigerator at 36°F–46°F. Once they are in use, Ozempic pens can be kept at room temperature, up to 86°F, and for a maximum of 56 days. Always be sure to keep semaglutide away from direct sunlight and heat, and check the storage instructions that come with your medication.

Semaglutide dosing myths: what doesn't affect how well it works

There’s a lot of information out there about semaglutide, and unfortunately, not all of it is accurate. Here are a few common myths and misconceptions.

Myth: A higher dose always means faster weight loss

It seems logical to assume that more medication equals faster results, but that’s not quite how semaglutide works. The dosing schedule, where you gradually increase the dose, exists for a reason. Increasing the dose too fast raises the risk of side effects like nausea and vomiting, all without necessarily improving results. The goal is to find the lowest possible effective dose.

Myth: Skipping doses will speed up results

Skipping doses doesn't accelerate weight loss. Semaglutide’s effectiveness is partly due to the level of medication present in your system. If you’re missing doses, this can reduce the effectiveness of the medication and may also cause side effects when you resume your regular dosing schedule.

Myth: Injecting in the same spot each time improves absorption

The reason it’s recommended to rotate injection sites is to help prevent skin irritation and ensure the medication gets absorbed properly. Sticking to one spot might seem fine, but it can actually cause something called lipohypertrophy, where there’s a buildup of fatty tissue under the skin, potentially affecting how the medication is absorbed.

Myth: You can take semaglutide without lifestyle changes and get the same results

People who combine semaglutide with healthier habits tend to see better results. Semaglutide is ideally prescribed alongside a healthy, reduced-calorie diet and increased physical activity. Lifestyle changes matter, even if you're taking semaglutide. Put simply, if you're still eating in a calorie surplus, semaglutide alone won't produce the same weight-loss results.

Tips to stay on track with your dosing schedule

The semaglutide injection is taken once a week, which keeps dosing simple. That said, it can still be easy to forget, so here are a few strategies to help you stay consistent:

• Set a weekly reminder on your phone on the same day each week.

• Tie your injection day to a routine activity you never skip, like Sunday morning coffee or a weekly call with a friend.

• Keep your medication and supplies somewhere visible and easy to access (within storage guidelines) so that you don’t forget.

• If you do miss a dose, check your medication guide for instructions. For Wegovy, if your next dose is more than 2 days away, you should take the missed dose as soon as you remember. If it's less than 2 days away, then skip it and resume your regular schedule. For Ozempic, take the missed dose if it's been 5 days or fewer since you missed it.

• Never double up on a dose to make up for a missed one.

Managing side effects

The most common semaglutide side effects are gastrointestinal, including: 

• Nausea

• Vomiting

• Diarrhea

• Constipation

• Abdominal discomfort

A 2022 review showed that gastrointestinal side effects are generally most intense when people first start taking semaglutide, or after increasing their dose, while side effects typically improve as the body adjusts.

A few things that can help:

• Eat smaller meals

• Chew your food slowly 

• Avoid fatty, greasy, or spicy foods 

• Stay well hydrated

• Consume more fiber in your diet if constipation is an issue

If any gastrointestinal side effects feel severe or aren’t improving over time, it’s best to reach out to your healthcare provider. They might suggest you don’t increase your dose, or they might recommend other ways to manage. When in doubt, reach out.

The bottom line

The semaglutide injection requires a gradual increase in dosage to help the body adjust and minimize side effects. It starts at 0.25mg weekly and increases every four weeks up to a maintenance dose.

Taking the semaglutide injection correctly means consistent weekly injections on the same day, rotating injection sites every week, storing it properly, and not skipping doses. Also, remember that more isn’t always better. The goal with semaglutide is to find the right dose, not the highest possible.

If you have questions about your semaglutide dosage and how it's affecting you, reach out to your healthcare provider. They can adjust your plan based on how you feel and your specific goals.
