Wegovy® (semaglutide) is a glucagon-like peptide 1 receptor (GLP-1) agonist that suppresses appetite and aids in weight loss. GLP-1 agonists activate receptors in the brain, stomach, and pancreas, inducing feelings of satiety and fullness, slowing stomach emptying, and increasing insulin release. After a series of clinical trials demonstrating its effectiveness and safety, Wegovy® was U.S. Food & Drug Administration (FDA)-approved for chronic weight management in 2021. 1 Other forms of semaglutide are used off-label to treat obesity. Wegovy is not a controlled substance, and it is not habit-forming.
Adults who meet either of the following criteria may be candidates for Wegovy® (semaglutide):
If you are interested in changing your body composition or losing weight, the first steps should always be lifestyle modifications such as regular, daily exercise at a moderate to vigorous level, decreased caloric intake, and behavioral changes that support weight loss.2 Lifestyle modifications have many health benefits, but frequently they are not enough to induce weight loss. Adding medications such as Wegovy® (semaglutide) can help support your weight loss efforts.3,4
Wegovy (semaglutide) should be stored in the refrigerator at a temperature between 36°F and 46°F (2°C and 8°C). It should not be frozen.
Before removing the pen cap, Wegovy can be stored from 8°C to 30°C (46°F to 86°F) in the original carton for up to 28 days. Keep Wegovy in its original container to protect it from light. If Wegovy is removed from the refrigerator, it should be used within 30 days. After 30 days, the medication should be discarded, and a new vial should be used. It is important to follow the storage and handling instructions provided with the medication to ensure its effectiveness and safety. Talk to your pharmacist if you have questions about how to store or use Wegovy.
According to the manufacturer, you can take Wegovy® with or without food. The auto-injecting pen is a single preset dose. The needle is hidden to prevent injury. It is typically administered by injection once a week. Each pen should be discarded in a sharps disposal container to prevent injury.
Wegovy (semaglutide) comes in five dose strengths:
Following your healthcare provider’s instructions, Wegovy (semaglutide) is dosed according to the following schedule:
Wegovy is typically self-administered by injection once a week. It is a subcutaneous injection delivered just under the skin in the abdomen, thigh, or upper arm. The specific dosing schedule for Wegovy will depend on the individual patient’s circumstances and their healthcare provider’s recommendations.
It is important to follow the dosing instructions provided by your healthcare provider and to take Wegovy at the same time each week. Wegovy can be taken with or without food.
As with any weight loss medication or treatment, the rate at which an individual will lose weight on Wegovy (semaglutide) will vary depending on several factors, including their diet, exercise habits, and metabolism. Some people may experience a more significant weight loss on semaglutide than others. Weight loss may begin within the first four weeks of treatment, but it is likely to take several months before you experience the full benefits of Wegovy. Overall, Wegovy gets excellent reviews.
Wegovy was tested by its manufacturer, Novo Nordisk, with eight Semaglutide Treatment Effects in People with Obesity (STEP) clinical trials. Clinical trial participants either received Wegovy or a placebo. The U.S. Food and Drug Administration Draft Guidance requires that participants taking medications for weight management must show a weight loss of over 5% or greater than those taking a placebo. In clinical trials, participants taking Wegovy had an average weight loss of 10% to 16% of their starting body weight. Those who received Wegovy lost an average of 34 pounds. The placebo group participants lost about 2.5% of their body weight, about six pounds.
“Wegovy (semaglutide) is not only superior at reducing body weight compared with other antidiabetic drugs, but it is also cardioprotective. Another significant benefit of semaglutide is that it can be used for long-term management of weight. With the recent approval of Wegovy, we could expect improvement in patients’ weight loss-related outcomes and quality of life.”Singh, Krauthamer, and Bjalme-Evans, BMJ Journal of Investigative Medicine (2022)3
