Saxenda<\/span><\/a> (liraglutide) and <\/span>Ozempic<\/span><\/a> (semaglutide) are name-brand prescription medications that can help people lose weight. They\u2019re both self-injected glucagon-like peptide 1 (GLP-1) receptor agonists, so they work in similar ways. Some people wonder which is better for weight loss, so let\u2019s take a closer look at the key differences between Saxenda and Ozempic.<\/span><\/p>\n

What\u2019s the difference between Saxenda and Ozempic?<\/span><\/h2>\n

Saxenda and Ozempic belong to the same drug class (<\/span>GLP-1<\/span><\/a>), but they have different active ingredients: liraglutide in Saxenda and semaglutide in Ozempic.\u00a0<\/span><\/p>\n

On a <\/span>molecular level<\/span><\/a>, liraglutide and semaglutide are nearly identical to each other and to the GLP-1 hormone that the body naturally produces. Tiny differences in structure end up making a significant impact on how long each drug lasts in the body and the average amount of weight people lose while taking them.\u00a0<\/span><\/p>\n

Dosage differences<\/span><\/h3>\n

The body metabolizes Saxenda much faster than it metabolizes Ozempic. Therefore, Saxenda is taken as a daily injection, whereas Ozempic is a weekly one. Both are <\/span>self-administered<\/span><\/a> under the skin via an injection pen.\u00a0<\/span><\/p>\n

\u201cA once-weekly injection of semaglutide is easier for many, but a once daily liraglutide dose could be best for people who\u2019ve had issues with side effects from semaglutide or prefer more flexibility,\u201d says <\/span>Rekha Kumar<\/span><\/a>, MD, an endocrinologist and obesity medicine specialist.<\/span><\/p>\n

As with all GLP-1s, Saxenda and Ozempic start at a low dose to reduce side effects. The dose is gradually increased under the guidance of the healthcare provider until the maximum tolerable dose is reached.\u00a0<\/span><\/p>\n

RELATED: <\/b>Ozempic dosage chart<\/b><\/a><\/p>\n

For Saxenda, that means starting at 0.6 mg per day for one week and increasing the dose by 0.6 mg every week thereafter. The maximum dose is 3 mg, so it\u2019s possible to reach this quantity in five weeks.\u00a0<\/span><\/p>\n

Ozempic is titrated at a much slower pace because it stays in the body longer. The starting dose is 0.25 mg each week. The healthcare provider will gradually increase the dose, with at least one month in between dosage increases. It takes at least four months to reach the <\/span>maximum dose<\/span><\/a> of 2 mg, although some people continue to take a smaller dose, such as 1 mg weekly.\u00a0<\/span><\/p>\n

With either medication, your healthcare provider may recommend a slower dosing schedule if your body needs a little more time to adjust.<\/span><\/p>\n

FDA-approved uses<\/span><\/h3>\n

The Food and Drug Administration (FDA) has approved Saxenda for weight loss and chronic weight management. Specifically, Saxenda is approved to treat adults with obesity and adolescents 12 years and older who weigh more than 60 kilograms (about 132 pounds) and have been diagnosed with obesity. It\u2019s also approved for adults who are considered overweight if they also have a <\/span>weight-related health condition<\/span><\/a>, such as high blood pressure, obstructive sleep apnea, gallstones, osteoarthritis, or heart disease.<\/span><\/p>\n

Ozempic is approved to control blood sugar levels in adults with <\/span>Type 2 diabetes<\/span><\/a> when used with a healthy diet and exercise. The FDA has also approved Ozempic for the <\/span>prevention of major adverse cardiovascular events<\/span><\/a> (MACE), including heart attack and stroke, in adults with both cardiovascular disease and Type 2 diabetes. Adults with chronic kidney disease and Type 2 diabetes can also be prescribed Ozempic to reduce the risk of cardiovascular death and further kidney damage. Ozempic is not FDA approved for weight loss, but healthcare providers often prescribe it <\/span>off-label<\/span><\/a> for this use.<\/span><\/p>\n

It\u2019s also important to note that Saxenda isn\u2019t the only liraglutide product available, nor is Ozempic the only option for semaglutide.\u00a0<\/span><\/p>\n

Under the brand name <\/span>Victoza<\/span><\/a>, liraglutide is FDA approved for blood sugar control in adults with Type 2 diabetes, along with diet and exercise, and to reduce the risk of MACE in adults with both Type 2 diabetes and cardiovascular disease.<\/span><\/p>\n

Semaglutide is FDA approved under the brand name <\/span>Wegovy<\/span><\/a> for weight loss and weight maintenance (along with diet and exercise) in people 12 years and older who have been diagnosed with obesity and in adults who are considered overweight and have at least one weight-related medical condition. It\u2019s also approved to reduce the risk of MACE in adults with heart disease who are considered overweight or obese, and to treat adults with <\/span>a type of fatty liver disease<\/span><\/a> called noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH) with moderate to advanced fibrosis.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Generic availability<\/span><\/h3>\n

Generic Saxenda <\/span>became available in 2025<\/span><\/a>. Known simply as liraglutide, <\/span>generic Saxenda<\/span><\/a> is much more affordable than the brand-name medication. We\u2019ll discuss costs in more detail below.<\/span><\/p>\n

Generic Ozempic is not yet available and may not hit the market until its <\/span>U.S. patent expires in 2032<\/span><\/a>. The patent for Wegovy is also set to expire in 2032.\u00a0<\/span><\/p>\n

How much weight can you lose on Saxenda?<\/span><\/h2>\n

Several studies<\/span><\/a> have concluded that liraglutide (Saxenda) results in an average of 9 to 13 pounds of weight loss over 56 weeks.<\/span><\/p>\n

In 2015, the SCALE Obesity and Prediabetes study group found that two-thirds of participants lost at least 5% of their body weight while taking liraglutide, and one-third lost at least 10%. An <\/span>additional SCALE study<\/span><\/a> confirmed that finding, recording an average weight loss of about 6% after 56 weeks of taking liraglutide.\u00a0<\/span><\/p>\n

The greatest amount of weight loss recorded by liraglutide researchers occurred in a 2024 <\/span>Turkish study<\/span><\/a>, where participants lost an average of about 41 pounds over 24 weeks.\u00a0\u00a0<\/span><\/p>\n

How much weight can you lose on Ozempic?<\/span><\/h2>\n

According to <\/span>researchers from Mayo Clinic<\/span><\/a>, nearly 9 out of every 10 people can expect to lose at least 5% of their body weight after taking semaglutide (Ozempic) for six months, and about half will lose 10% or more.\u00a0<\/span><\/p>\n

Higher doses of semaglutide given over a longer period of time tended to result in the most weight loss. Participants in a 68-week study lost an average of about <\/span>34 pounds<\/span><\/a> while on 2.4 mg of semaglutide. This equaled a weight loss of about 15%\u201317%. In contrast, the placebo (inactive treatment) group lost about 6 pounds on average, or about 2% of their body weight.\u00a0<\/span><\/p>\n

Another study<\/span><\/a> found that people taking semaglutide lost an average of 10% of their body weight in the first 65 weeks, and the loss was maintained until the study ended at more than 200 weeks. In contrast, the placebo group lost 1.5% of their body weight, and the weight loss plateaued at about 26 weeks.\u00a0<\/span><\/p>\n

Oral semaglutide (sold under the brand name <\/span>Rybelsus<\/span><\/a>) has also been studied, but it tends to result in less weight loss than injectable semaglutide. For example, one study found that 14 mg of oral semaglutide per week for 52 weeks resulted in an average of <\/span>10 pounds lost<\/span><\/a>.\u00a0<\/span><\/p>\n

Is Saxenda better than Ozempic for weight loss?<\/span><\/h2>\n

Studies tend to conclude that Ozempic (semaglutide) is more effective for weight loss than Saxenda (liraglutide):<\/span><\/p>\n
