Weight loss medications are available for some people when diet management and exercise are not enough. Most of these medications work by reducing appetite. Various options are available via prescription and over the counter (OTC).
According to 2017–2020 data, obesity prevalence rose from
While prescription and OTC medications are available, only one nonprescription medication has Food and Drug Administration (FDA) approval. Healthcare professionals may recommend specific diet and exercise programs alongside prescription weight loss medication.
This article discusses what weight loss medication is, how it works, and whether it is safe. It also lists the available medications, alternatives, and when to contact a doctor.
Weight loss medications typically work by suppressing a person’s appetite.
It is not completely clear how GLP-1 medications work. However, studies have shown that these drugs help to suppress hunger and manage appetite.
Research from 2021 states these types of medications can help with weight loss by decreasing energy intake and increasing energy expenditure.
Another type of weight loss medication is an anorectic. Further 2021 research states that these suppress appetite, minimize fat absorption, and increase the feeling of fullness.
Some weight loss medication is available on prescription, while others are OTC options.
Prescription weight loss medications are available as injections or capsules. Two types of weight loss medications are glucagon-like peptide agonists (GLP-1) and anorectics.
The following medication prices are current listings from Blink Health. However, a person may be able to get them at a lower price at other pharmacies and by using health insurance.
These are GLP-1 weight loss medications, which people typically take them via injection. It is not yet clear how GLP-1 medications work, but studies have found they can help suppress a person’s appetite by slowing the time it takes to empty the stomach, thus making a person feel full for longer.
Some GLP-1 medications for weight loss include:
Wegovy is the branded version of semaglutide 2.4mg and has FDA approval. Common side effects include nausea, vomiting, diarrhea, and constipation. People take Wegovy as a weekly injection.
Wegovy is available from several pharmacies. Blink Health lists it for $21,138.
This is the branded name for semaglutide in a dose of 1mg. The FDA only approves this drug as a treatment for type 2 diabetes, but healthcare professionals may prescribe it off-label as a weight-loss medication.
Using a drug off-label means a person takes it for a purpose other than the FDA approval.

Mounjaro is available from Blink Health for $16,031.36.
As Mounjaro does not have FDA approval as a weight loss medication, insurance companies will not usually cover it for this purpose. However, health insurance can cover Mounjaro for diabetes.
