Injectable GLP-1 medication can help manage type 2 diabetes and, when combined with diet and exercise, aid weight loss. Several telemedicine companies offer GLP-1 medications to help support health and may offer some drugs off-label for weight loss.
GLP-1 medication can help people with overweight or obesity who have at least one weight-related health condition manage their weight.
Some medications, such as Ozempic (semaglutide), only have Food and Drug Administration (FDA) approval for the management of type 2 diabetes. However, healthcare professionals may prescribe them off-label for weight loss.

These medications mimic gut peptides, which help regulate blood sugar. Research from 2021 has found that, in conjunction with appropriate lifestyle habits, they can help people lose a significant amount of weight or maintain weight loss.
Incretin hormones cause the body to produce insulin when eating sugar, called the incretin effect. People with type 2 diabetes either have a decreased or absent incretin effect. GLP-1 medication can help manage blood sugar by
One effect of GLP-1 medication is delayed gastric emptying, which can make people feel fuller for longer. This effect has led to companies creating GLP-1 medication specifically for weight management, including the FDA-approved drugs Wegovy and Zepbound.
What experts say about using GLP-1 medication for weight loss
“Only two anti-diabetic medications are FDA-approved for weight management in people who do not have diabetes: semaglutide (Wegovy) and liraglutide (Saxenda). Ozempic and Rybelsus are two other brands of semaglutide on the market that are approved by the FDA for glycemic control in diabetes but not for weight management.
“Ozempic is only prescribed to type 2 diabetic patients for the sole purpose of glycemic control. Because of the increased risk of adverse reactions, it is not recommended for use in the absence of diabetes. This medication’s safety profile has not been studied in patients under the age of 18, pregnant and lactating people, or those with normal BMIs.”
At the time of publishing, the FDA has only approved three GLP-1 agonists for weight loss: Wegovy (semaglutide), Zepbound (tirzepatide), and Saxenda (liraglutide). These medications are only available to people with a body mass index (BMI) of 27 or over with at least one weight-related health condition or those with a BMI of 30 or over.
Wegovy
Wegovy is available as a once-weekly injection in several doses, ranging from 0.25 to 2.4 milligrams (mg). The FDA approved this drug for use in weight management in

Two popular GLP-1 medications, Ozempic and Mounjaro (tirzepatide), only have FDA approval for the management of type 2 diabetes. However, some healthcare professionals may prescribe these off-label for weight loss.

Ozempic
Ozempic is available in doses of 2 mg to 8 mg in once-weekly injections. Research has found that Ozempic
A
Mounjaro
Mounjaro is available in 2.5 to 15 mg once-weekly injections. Its active ingredient is tirzepatide, a GIP receptor agonist that activates both the GLP-1 and GIP receptors to improve blood sugar regulation. This dual effect may make tirzepatide more effective than other injectable diabetes medications.
According to 2023 research, Mounjaro is very effective for weight loss, with people losing

The FDA has approved the following GLP-1 medications for heart health.
Victoza (liraglutide)
In 2017, the FDA approved Victoza (liraglutide) to reduce the risk of heart disease and stroke. It based its decision on the results from the
The company states that the trial found that Victoza led to:
- a 22% reduction in cardiovascular death compared with a placebo
- a 12% lower risk of non-fatal heart attack
- an 11% risk reduction of non-fatal strokes
Trulicity (dulaglutide)
In 2020 the FDA approved Trulicity (dulaglutide) for the reduction of major adverse cardiovascular events (MACE) in adults with type 2 diabetes who have established cardiovascular disease or multiple cardiovascular risk factors. The FDA based its decision on results from the Researching Cardiovascular Events with a Weekly Incretin in Diabetes (REWIND) trial. Researchers tested the drug on patients with established CVD and CV risk factor subgroups. The results showed that Trulicity reduced CV events by 12% in the study population.
Ozempic and Wegovy (semaglutide)
In 2020 The FDA approved Ozempic (semaglutide) for the reduction of stroke, heart attack, and other major adverse cardiovascular events (MACE) in adults with type 2 diabetes and heart disease. The FDA based its decision on outcomes from the 2-year SUSTAIN 6 trial where Ozempic reduced the risk of MACE by 26%.
More recently, in 2024, the
Regulating blood sugar and helping with weight management are not the only benefits of GLP-1 medications. A
- diabetic cardiomyopathy
- myocardial infarction
- stroke
- high blood pressure
- dyslipidemia
Some of the most common side effects of these medications are:
- decreased appetite
- indigestion
- abdominal pain
- nausea
- vomiting
- constipation
- diarrhea
Possible serious risks and side effects include:
- serious allergic reactions
- low blood sugar
- diabetic retinopathy complications
- severe stomach, gallbladder, or kidney problems
- inflammation of the pancreas, or pancreatitis
Rodent studies have also shown that semaglutide, tirzepatide, and liraglutide can cause thyroid C-cell tumors. Health experts do not yet know whether these injectable diabetes drugs can cause tumors in humans, but it is important to understand the risk. All of these medications have FDA-boxed warnings.
Manufacturers generally warn against using these drugs if a person has a personal or family history of medullary thyroid carcinoma, a type of thyroid cancer, or multiple endocrine neoplasia syndrome type 2 (MEN 2), an endocrine system condition.

Healthcare professionals only recommend injectable diabetes drugs for weight loss for people who either have obesity or overweight and another weight-related medical condition.
Weight-related medical conditions include:
- type 2 diabetes
- hypertension (high blood pressure)
- higher levels of “bad” cholesterol
- coronary heart disease
- stroke
Some doctors may prescribe injectable diabetes drugs for weight loss if a person has overweight or obesity and has indications of prediabetes.
Manufacturers did not design these drugs for people with moderate weight who want to lose additional weight. Despite their popularity on social media, these medications carry significant risks and can be harmful to those who do not need them.
What experts say about using Ozempic at a moderate weight
“Ozempic helps regulate blood glucose by stimulating the pancreas to release more insulin when blood glucose levels are elevated. This can cause severe hypoglycemia (low blood sugar levels) in people who do not have diabetes, necessitating immediate medical attention.
Other serious side effects include pancreatitis (pancreatic inflammation), the development of thyroid tumors, and gallbladder problems.”
Research from 2023 shows that semaglutide, such as Ozempic and Wegovy, and tirzepatide, such as Mounjaro and Zepbound, are more effective than liraglutide for weight loss.
Metformin is not a GLP-1 drug — it is in a class of medications called biguanides.
Healthcare professionals may prescribe metformin alongside GLP-1 medication.
Ozempic is a brand name for a type of GLP-1 drug called semaglutide. There are several other GLP-1 medications, and healthcare professionals will work closely with each person to determine which one best suits their needs.
The FDA has approved several GLP-1s for managing type 2 diabetes and weight loss. Healthcare professionals may prescribe type 2 diabetes medication for weight loss off-label if people meet certain criteria.
People will need to be obese or overweight and have at least one weight-related health condition to use GLP-1 medications. Some drugs, such as those containing semaglutide and tirzepatide, are more effective than others.
