Saxenda and Ozempic are both GLP-1 medications, and both can help people lose weight. But they are not the same drug, and one of them is not even approved for weight loss. Here is a plain-language look at how they compare, and how a doctor decides which one fits you.
What each drug actually is
Saxenda is the brand name for liraglutide. It is a GLP-1 you inject once a day, and the FDA has approved it for weight loss.
Ozempic is the brand name for semaglutide. It is a GLP-1 you inject once a week. Here is the part that trips people up: Ozempic is FDA-approved for type 2 diabetes, not for weight loss. The semaglutide brand that is approved for weight loss is Wegovy. Same drug, different label and dose. Doctors sometimes prescribe Ozempic off-label for weight loss, which means they use an approved drug for a purpose the FDA has not officially signed off on. If the goal is weight loss, the on-label semaglutide choice is Wegovy. Our Ozempic vs Wegovy guide breaks that down.
How much weight can you lose?
In research that puts the two side by side, weekly semaglutide tends to produce more weight loss on average than daily liraglutide. Newer options like Zepbound (tirzepatide) generally do even more. That said, averages are not promises. Some people lose a lot on Saxenda, and some do not respond well to semaglutide. Your starting weight, your habits, and how your body reacts all matter. A drug that works great for a friend may do less for you.
Daily vs weekly injections
This is the clearest practical difference. Saxenda is a shot every single day. Ozempic (and Wegovy) is one shot a week. Both use a small pen with a fine needle, and both go into the fat just under the skin, usually the belly, thigh, or upper arm.
Once a week is easier to remember and easier to stick with for most people. But some patients like the daily routine, or find that steady daily dosing feels gentler on their stomach. Neither is wrong. It comes down to what you will actually keep up with.
Side effects
Both drugs cause similar issues, mostly in the gut. Nausea is the most common one. You may also get constipation, diarrhea, or a bit of vomiting, especially in the first few weeks as the dose goes up. These usually ease over time. Going slow with dose increases helps a lot. Our guide on GLP-1 side effects covers what to expect and how to manage it. Tell your doctor about any severe or lasting symptoms.
What about cost?
Brand-name GLP-1s are expensive at full list price, often more than $1,000 a month. Most people do not pay the sticker price, though. Manufacturer savings cards, self-pay pharmacy options, and insurance can bring the cost down a lot. Coverage is the big variable, so it is worth checking your plan first. See our guides on insurance coverage, pricing, and finding affordable clinics. One note for 2026: cheap compounded versions are no longer a routine option, so plan around the brand-name drugs.
Which one is better?
For most people focused on weight loss, weekly semaglutide (as Wegovy) or tirzepatide will likely do more with fewer shots. But Saxenda still has a real place, especially if your insurance covers it, if you tolerate daily dosing better, or if your provider recommends it for your situation. There is no single winner. The best choice is the one a doctor matches to your health, your budget, and your routine.
