You've tried cutting carbs, counting calories, and exercising more—yet the scale barely moves. Now, you’re considering medication, but even that choice feels overwhelming. 

Liraglutide or semaglutide? One requires daily injections, the other weekly. One seems to work faster, but is it worth the side effects? And what about cost, insurance, or what happens if you’re still hungry while taking it?

Here’s the answer: semaglutide is generally more effective for weight loss, with studies showing greater weight reduction compared to liraglutide. However, liraglutide may be a better option for those who prefer a daily routine or have different insurance coverage.

In this guide, we’ll compare their weight loss results, cost, dosing schedules, and side effects—so you can confidently choose the option that fits your body, budget, and lifestyle.

What is Liraglutide?

Liraglutide helps regulate blood sugar levels and reduce appetite. Originally developed for treatment of type 2 diabetes under the brand name Victoza, it is also FDA-approved for weight loss as Saxenda.

As a GLP-1 receptor agonist, liraglutide supports long-term weight management by reducing cravings and promoting satiety (feelings of fullness). It is administered once daily via injection and is often prescribed alongside diet and exercise for weight loss.

What is Semaglutide?

Semaglutide is also a GLP-1 receptor agonist designed to help regulate blood sugar and suppress appetite. Originally approved for type 2 diabetes under the brand name Ozempic, it is also FDA-approved for weight loss as Wegovy.

Unlike liraglutide, semaglutide treatment is taken once weekly, making it a more convenient option for many patients. 

Clinical studies have shown that semaglutide leads to greater weight loss compared to liraglutide, making it a preferred choice for those looking for more significant results with fewer injections. Additionally, oral semaglutide is available as an alternative to injections, offering another option for patients seeking a GLP-1 weight loss program that fits their lifestyle.

Semaglutide vs Liraglutide: Key Differences 

While both liraglutide and semaglutide are GLP-1 receptor agonists used for weight loss, they differ in how they work, how long they stay in your system, and how quickly they take effect. These differences can impact which medication is the best fit for your lifestyle and goals.

Difference #1: Strength of appetite suppression

Both medications reduce hunger and slow digestion, but semaglutide has a stronger appetite-suppressing effect and shows a greater reduction in body weight in clinical trials. If hunger control is a key concern, semaglutide may be the better option.

Difference #2: How long they stay in your system

One of the biggest differences is how long the medications last in your body:

• Liraglutide has a half-life of about 13 hours, requiring daily injections to maintain its effect.
• Semaglutide has a half-life of about 7 days, allowing for once-weekly injections with a more sustained effect.

If you prefer fewer injections and a more consistent effect, semaglutide might be the better fit.

Difference #3: How quickly you increase your dose

• Liraglutide reaches its full dose within weeks, meaning you may feel its effects sooner but might also experience more initial side effects.
• Semaglutide requires a slow dose increase over several months to help reduce nausea and digestive issues.

If you want to ease into treatment more gradually, semaglutide may be more tolerable.

Difference #4: Who it’s best for

• Liraglutide may be better for those who prefer a daily routine or who can’t tolerate semaglutide’s stronger effects.
• Semaglutide is often the better choice for faster weight loss with fewer injections and stronger hunger control.

Difference #5: Insurance coverage and availability

While insurance coverage varies, semaglutide is more likely to be covered for weight loss than liraglutide. Some providers may also have restrictions on prescribing liraglutide for weight management, as it was originally developed for diabetes. Checking with your insurance provider can help determine which option is more accessible for you.

Potential Side Effects of Liraglutide and Semaglutide

Both liraglutide and semaglutide share similar adverse effects, primarily related to the digestive system. While most side effects are mild and temporary, some users may experience more severe reactions. 

Liraglutide

Common side effects:

• Nausea and vomiting
• Diarrhea or constipation
• Decreased appetite
• Fatigue
• Increased heart rate

Rare but serious side effects:

• Pancreatitis

Common side effects:

Some users may find that they are still hungry on semaglutide, which can impact weight loss results. Adjusting your semaglutide diet plan, ensuring adequate protein intake, and consulting your doctor about dosage modifications may help. And, if you're not losing weight on semaglutide, factors like diet, physical activity, and medication adherence should also be reviewed to optimize results.

If you experience persistent (or severe) side effects, consult a healthcare provider to determine the best course of action.

Cost & Insurance Coverage of Liraglutide and Semaglutide

Liraglutide and Semaglutide: Drug Interactions

Both liraglutide and semaglutide can interact with other medications, affecting their effectiveness or increasing the risk of side effects. If you’re taking any of the following medications, consult your healthcare provider before starting a GLP-1 medication.

Medications That May Interact with Liraglutide & Semaglutide

• Insulin or other diabetes medications – May increase the risk of low blood sugar (hypoglycemia).
• Oral medications – Since GLP-1 agonists slow digestion, they can affect the absorption of oral medications.
• Blood pressure medications – May cause dizziness or fainting due to lowered blood pressure.
• Warfarin (blood thinners) – Can increase bleeding risk if absorption is altered.
• Certain antidepressants – Some SSRIs and SNRIs may interact, potentially affecting appetite suppression.

To avoid complications, discuss your medication list with a doctor before starting liraglutide or semaglutide.

Warnings and Precautions Before Taking These GLP-1 Medications

Before starting liraglutide or semaglutide, it's important to consider potential risks. These medications may not be suitable for everyone, especially those with certain medical conditions.

Liraglutide

• Not recommended for individuals with a history of pancreatitis or thyroid tumors.
• May cause gallbladder issues, leading to gallstones in some users.
• Liraglutide may cause an increase in heart rate, so people with a history of cardiovascular disease should consult their doctor before starting treatment.

Semaglutide

• Should not be used if you have a personal or family history of medullary thyroid cancer.
• May increase the risk of diabetic retinopathy in people with type 2 diabetes.
• Can cause severe gastrointestinal issues, including persistent nausea and vomiting.

Always consult a healthcare provider before starting GLP-1 medications, especially if you have existing health concerns.

Can I Switch Between Liraglutide and Semaglutide?

Yes, it is possible to switch between liraglutide and semaglutide, but it should be done under the guidance of a healthcare provider. The transition process depends on your tolerance, dosage, and treatment goals.

• If you’re switching from liraglutide to semaglutide, you may need to gradually increase the semaglutide dose to minimize side effects.
• If you’re switching from semaglutide to liraglutide, you’ll likely start at a lower liraglutide dose and increase gradually.
• Some users may experience temporary side effects, including nausea or digestive issues, as their body adjusts.

Your doctor will help determine the safest and most effective transition plan based on your medical history and weight loss progress.
