Saxenda (liraglutide) is a prescription drug that’s used for weight management. Saxenda comes as a liquid solution inside a prefilled injection pen.
Saxenda is used to help with weight loss and long-term weight management in:
- adults and some children who have obesity
- adults who are overweight and have a weight-related condition
This drug is meant to be part of a long-term weight management plan that includes a reduced-calorie diet and increased exercise. To learn more, see the “Is Saxenda used for weight loss and weight management?” section below.
Saxenda basics
Saxenda contains the active ingredient liraglutide. (An active ingredient is what makes a drug work.) It belongs to a group of drugs called GLP-1 agonists.
Saxenda is a brand-name medication that’s not currently available in generic form.
You may wonder how Saxenda and Wegovy compare. Saxenda contains the active ingredient liraglutide, and Wegovy contains semaglutide. Both medications are prescribed for weight loss and management. Wegovy can also help reduce the risk of serious cardiovascular problems.
Saxenda and Wegovy are injected under the skin. Saxenda is used once daily, and Wegovy is used once weekly.
For more information about either drug, talk with your doctor. They will recommend the best treatment option for you.
Ozempic and Saxenda are prescribed for different purposes. Ozempic is used in people with type 2 diabetes, to help manage blood sugar levels and to reduce the risk of serious cardiovascular problems. It’s not approved for weight loss and weight management like Saxenda. However, doctors might prescribe Ozempic off-label for weight loss. (With off-label use, a drug that’s approved for certain conditions is prescribed for another purpose.)
These drugs contain different active ingredients: Ozempic contains semaglutide, and Saxenda contains liraglutide. Both drugs come in prefilled injection pens.
For details about how Saxenda and Ozempic compare, you can talk with your pharmacist or your doctor.
Like most drugs, Saxenda may cause mild or serious side effects. The lists below describe some of the more common side effects that Saxenda may cause. These lists don’t include all possible side effects of using Saxenda for weight loss.
Keep in mind that side effects of a drug can depend on:

Boxed warning
Saxenda has a boxed warning about the risk of thyroid cancer. A boxed warning is the most serious warning from the Food and Drug Administration (FDA).
There may be a possible risk of thyroid cancer with Saxenda. In animal studies, 厂补虫别苍诲补’蝉 active ingredient, liraglutide, was found to cause thyroid tumors in animals. But it’s not known if the drug causes thyroid cancer in humans.
Due to the possible risk of thyroid cancer, your doctor will likely not prescribe Saxenda if:
- you or a member of your close family have had a rare type of thyroid cancer called medullary thyroid cancer (MTC)
- you have multiple endocrine neoplasia syndrome type 2 (MEN 2), a rare inherited condition that raises your risk of thyroid cancer
Symptoms of thyroid cancer may include:
- a hoarse voice that doesn’t go away
- a lump in your neck
- trouble swallowing
- trouble breathing
- shortness of breath
What might help
Before starting Saxenda, talk with your doctor about your medical history. Tell them about any conditions you have. This includes conditions that may increase your risk of thyroid cancer, such as MTC or MEN 2. Informing your doctor about your medical history will help them determine whether Saxenda is safe for you to take.
Contact your doctor right away if you have symptoms of thyroid cancer during Saxenda treatment.
Nausea
You may have nausea with Saxenda. This is usually mild and should lessen as you continue to use Saxenda.
In studies, nausea was the most common side effect reported with Saxenda.
Keep in mind that nausea can sometimes happen with 厂补虫别苍诲补’蝉 more serious side effects. These include kidney problems, gallbladder problems, pancreatitis, and low blood sugar level.
What might help
If you have nausea from Saxenda, here are a few tips to try to help ease it:
- Avoid eating large meals. Instead, eat smaller amounts more frequently.
- Avoid rich, spicy, or greasy foods.
- Take frequent sips of water.
- Try ginger or peppermint teas.
- Avoid wearing tight clothing.
- Avoid lying down after eating.
Be sure to drink plenty of fluids, even if you have nausea or vomiting. If you become dehydrated, this can raise your risk of kidney problems with Saxenda.
If you have nausea that’s bothersome, severe, or stops you from eating and drinking as you usually would, talk with your doctor. Also, talk with your doctor if you have nausea with other symptoms, such as abdominal pain, fever, or urinating less than usual.
Your doctor may recommend other ways to ease nausea. They may also check that your nausea is not caused by a more serious condition.
Headache
You may have headaches during Saxenda treatment. These headaches are usually mild and tend to go away as your body gets used to Saxenda.
In studies, headaches were commonly reported in adults who took Saxenda. But they weren’t commonly reported in children.
What might help
If you have bothersome headaches with Saxenda, try taking an over-the-counter pain reliever, such as acetaminophen (Tylenol). Ask your doctor or pharmacist to recommend a suitable product.
If you have headaches that are severe or do not get better, talk with your doctor.
Allergic reactionSome people may have an allergic reaction to Saxenda.
Symptoms of a mild allergic reaction can include:
A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include:
- swelling under your skin, typically in your eyelids, lips, hands, or feet
- swelling of your tongue, mouth, or throat, which can cause trouble breathing
Call your doctor right away if you have an allergic reaction to Saxenda. But if you think you’re having a medical emergency, call 911 or your local emergency number.
Find answers to some commonly asked questions about Saxenda.
What can I expect before and after Saxenda treatment? Are reviews available from people who’ve used the drug?
Before you start Saxenda, your doctor will help you develop a long-term weight management plan. This should include a low calorie diet and increased exercise. You can also work with a dietitian or nutritionist to develop your plan.
Including Saxenda as part of your plan can help you lose weight and keep it off long term. But different people may have different results with Saxenda. The amount of weight you may lose and any side effects you have will depend on your personal situation.
厂补虫别苍诲补’蝉 prescribing information has details about side effects and how much weight people lost with Saxenda in studies. But keep in mind that everyone’s experience with this drug will be different.
To find out more about what you can expect with Saxenda, talk with your doctor.
Are Wegovy, Contrave, Ozempic, Qsymia, and phentermine weight loss alternatives for Saxenda?
Yes, some of these drugs are. Wegovy (semaglutide), Contrave (naltrexone/bupropion), Qsymia (phentermine/topiramate), and phentermine (Adipex-P, Lomaira) can each be used for weight loss.
The exception is Ozempic (semaglutide), which is not used for weight loss. Instead, it’s used for type 2 diabetes.
If you’d like to learn more about alternatives to Saxenda, talk with your doctor or pharmacist. You can also see the “Saxenda vs. Wegovy” and “Saxenda vs. Ozempic” sections in this article for more information.
How does Saxenda work? Is it a type of insulin?
No, Saxenda isn’t a type of insulin. Insulin is a hormone that helps manage your blood sugar level. Instead, Saxenda is a type of drug called a GLP-1 agonist.
GLP-1 is another hormone that helps manage blood sugar levels. It also regulates appetite.
Saxenda works by acting in the same way as GLP-1. (The way a drug works is called its mechanism of action.) Specifically, Saxenda causes your stomach to empty more slowly, which helps you feel fuller after eating. Saxenda also helps reduce your appetite.
Saxenda helps you consume fewer calories, which helps with weight management.
Does Saxenda treat diabetes?
No, Saxenda does not treat diabetes. It’s only used for weight loss.
Saxenda contains the same active drug as a diabetes medication called Victoza. The active drug in both these medications is liraglutide. However, Victoza is used in a lower dosage for diabetes than Saxenda is for weight loss.
How should I store Saxenda?
When you receive a new Saxenda pen, store it in your refrigerator until you start using it. Make sure the pen doesn’t freeze. Do not use Saxenda if it has been frozen.
When you start using the new pen, you can take it out of the fridge and keep it at room temperature. Or you can continue storing it in your fridge. Either way, the pen is good for 30 days after you start using it. If there’s any medication left in the pen after 30 days, safely dispose of the pen.
Never store your pen with a needle attached. Be sure to remove the needle and replace the pen cap after each dose of Saxenda.
For more information about Saxenda storage and disposal, talk with your doctor or pharmacist.
Your doctor will recommend the dosage of Saxenda that’s right for you. Below are commonly used dosages, but always take the dosage your doctor prescribes.
Form and strength
厂补虫别苍诲补’蝉 form and strength are listed below.
Saxenda form: Injection pen
Saxenda comes as a liquid solution inside a prefilled injection pen. You’ll use the pen to inject Saxenda under your skin. Your doctor will teach you how to give yourself an injection using the pen.
Saxenda strength
The Saxenda pen comes in one strength. It contains 18 milligrams of liraglutide in 3 milliliters of solution (18 mg/3 mL). You can set the pen to inject the following doses:
- 0.6 mg
- 1.2 mg
- 1.8 mg
- 2.4 mg
- 3 mg
Recommended dosages
The recommended starting dose of Saxenda for adults and children ages 12 years and older is 0.6 mg. You’ll likely take this dose once each day for the first week of treatment. After this, your doctor will gradually increase your dosage over the next few weeks.
The usual recommended dosages are:
- Week 1: 0.6 mg once each day
- Week 2: 1.2 mg once each day
- Week 3: 1.8 mg once each day
- Week 4: 2.4 mg once each day
- Weeks 5 and beyond: 3 mg once each day
Try to take your dose at around the same time each day.
If you have bothersome side effects after a dose increase, talk with your doctor. They may recommend delaying your next dose increase for about a week until your side effects lessen.
The recommended maintenance (long-term) dose for adults and children is 3 mg once each day. Adults who have unacceptable side effects at this dose will usually need to stop Saxenda treatment. Children with unacceptable side effects at this dose may have their maintenance dose lowered to 2.4 mg once each day.
Questions about 厂补虫别苍诲补’蝉 dosage
Here are some common questions about 厂补虫别苍诲补’蝉 dosage.
- What if I miss a dose of Saxenda? If you miss a dose, skip the missed dose and inject your next dose as scheduled. Do not take any extra doses to make up for missed doses. If you miss three or more doses in a row, talk with your doctor. They’ll likely have you resume Saxenda treatment at the lower starting dose. Then they’ll gradually increase this dose each week, just like at the start of treatment.
- Will I need to use Saxenda long term? Yes, if Saxenda is safe and effective for you, you’ll likely use it long term.
- How long does Saxenda take to work? It may take a couple of weeks before you start losing weight with Saxenda. It’s recommended that doctors check the progress of adults after 4 months and children after 3 months. If you have not lost the amount of weight recommended by your doctor by this time, it’s unlikely Saxenda is working for you. Your doctor will probably recommend stopping treatment.
Note: You can refer to this Saxenda dosage article for more details.

Q:
Is it safe to use Saxenda with metformin?
AnonymousA:
Metformin (Riomet, Fortamet, Glumetza, others) is a medication commonly used for type 2 diabetes. If you take metformin, it’s usually safe to use Saxenda as well. Metformin isn’t known to interact with Saxenda.
But both medications commonly cause digestive side effects, such as nausea and upset stomach. So you could be more likely to have these side effects if you use both medications.
If you use Saxenda with metformin, tell your doctor if you have bothersome digestive side effects. They can suggest ways to help reduce these problems. For example, they may recommend adjusting your doses or trying a different form of metformin. Long-acting forms of metformin tend to cause fewer digestive problems than short-acting forms.
