Semaglutide Dosage Charts For Weight Loss: Understanding the Prescription (Plus Printable PDFs!)
Dosage charts can be confusing to understand — that's why we discussed how to read them with medical experts.
There’s a lot to consider before starting GLP-1s. Will you opt for a semaglutide or tirzepatide medication? Also, how long will you be taking it — and at what rate will you increase your dosage? Medication manufacturers have general dosage guidelines, but what does it all mean? Woman’s World spoke with medical experts about dosage charts, who helped us break down how semaglutide and tirzepatide dosing actually works.
If you don’t want to learn more about the reasons behind GLP-1 dosing, you can just jump to our dosage charts down below.

Dosage charts vary by medication and use
Wegovy and Ozempic are both semaglutide medications, while Mounjaro and Zepbound are both tirzepatide medications. However, any FDA-approved medication has different dosing guidelines for different needs (like taking it for diabetes versus weight loss). HaVy Ngo-Hamilton, Pharm.D., who is a pharmacist and clinical consultant at BuzzRx, tells Woman’s World you should always plan to adhere to FDA guidelines, unless told otherwise by your doctor.
“Wegovy and Ozempic both contain semaglutide as their active ingredient; however, they have different FDA-approved indications,” she explains. “Ozempic is approved to treat type 2 diabetes, while Wegovy is approved for chronic weight management. Besides their approved uses, Wegovy and Ozempic have different dosing guidelines.”
Doctors sometimes stray from FDA guidelines
Generally, medical experts adhere to recommended dosage for each medication. FDA approval means the medication’s dosage recommendation is safe and effective for what it’s being used for. And while doctors almost always opt for the recommended starting dose, sometimes doctors will stray from the guidelines after the first dose.
“Based on the patient’s response to the medication and how they tolerate the side effects, healthcare providers may use their clinical judgment to adjust the dosing regimen to best suit their patient,” Ngo-Hamilton adds. “This can be for several reasons, including how the patient tolerates the medication’s side effects and their clinical responses to the treatment.”
A typical dosage chart increases until the goal dose is met
Dosage charts show patients the trajectory of their progress. They may increase weekly or decrease, depending on if you’re just getting started, or weaning off it. “For example, on Wegovy, a patient will start on 0.25 mg once weekly, stay on that dose for four weeks and then progress to 0.5 mg,” Dr. Crystal Wyllie of Zava Online Doctor explains. “We prescribe patient’s scheduled doses, increasing incrementally, so their bodies can adjust gradually.”
Doses start low, and often increase over time
Patients generally want to meet their “goal dose” quickly, to see the most progress. But, it’s important to take it slowly. That way, Dr. Wyllie says, the body can adjust to either the semaglutide or tirzepatide injection.
“If a patient experiences side effects, their doctor may suggest they stay on the same dose for longer to give their body more time to adjust,” Dr. Wyllie says. “In more severe cases, the doctor may suggest they reduce their dose temporarily before reattempting an increase.”
Tirzepatide and Semaglutide Weekly Dosage Charts
Even medications in the same category have different dosages
Tirzepatide medications impact two receptors instead of one, which is why tirzepatide dosage is increased more slowly than semaglutide. But even medications within the same category as dosed differently. This is because medications gain approval for different uses.
“Even with the same active ingredient, Ozempic and Wegovy have different dosing recommendations,” Dr. Hgo-Hamilton explains. “Meanwhile, even though Zepbound and Mounjaro have the same dosing regimen, their recommended maintenance doses differ, too. The recommended dosages are based on the data from clinical trials for that specific use.”
For both types, higher doses may lead to negative side effects
Increasing the dosage for both types of medications can come with negative side effects (nausea, vomiting, constipation, fatigue, loss of appetite and more). That said, Dr. Ngo-Hamilton explains it’s important to stay on the current dose for at least four weeks to build tolerance.
“Working closely and communicating effectively with your provider is necessary for your treatment success,” she tells us. “For instance, even though the recommendation is to have at least 4 weeks between dose increases, your provider may advise you to stay on a certain dose for a longer duration to help with the medication’s side effects.”
All dosage charts look quite different
Even though you may be taking semaglutide, the brand varies by dose. Discuss with a doctor your dosage plan, to ensure you’re fully on board.
