New Weight Loss Medication Wegovy™ Approved by the FDAPosted: Jun 04 in Weight Loss Medication by Dr. Lazarus
The molecule semaglutide has been used for the treatment of type II diabetes for the past 5 years at doses of up to 1 mg. Novo Nordisk is also seeking an approval for a 2 mg weekly dose for diabetes. However, Wegovy™, the 2.4 mg dose, is approved for chronic weight management whether or not the person has diabetes.
Wegovy™ is the 5th new weight loss medication approved by the FDA since 2012. The mechanism of action is similar to Saxenda™. It is known as a GLP-1 analogue (glucagon like peptide-1). GLP-1 is a hormone your small intestine normally makes in response to food intake. It signals your brain and your stomach that you are done eating, providing control of appetite, satiety, and a decrease in stomach peristalsis (pumping). The existing Ozempic™ has been a great drug to have in our armamentarium against diabetes, because it is extremely effective and safe. In fact, in addition to lowering the blood sugars, it lowers the risk of heart attack and stroke.
Now referred to as anti-obesity medications, Wegovy™ also offers very convenient dosing. It is a self-administered injection, and is only injected once per week. The injections are simple and don’t hurt. Imagine doing an injection once a week during the weekend and then not having to take any pills all week!
Wegovy™ vs Saxenda™
We have had great experience with Saxenda™ over the past 7 years, but Saxenda™ requires an injection every day. Further, compared to the Saxenda™, the Wegovy™ offers more than 50% greater weight loss on average, with the typical patient losing 15% of their body weight (34 pounds). Many even lose 20% – or more! This is significantly more potent than all of the currently available weight loss medications. Novo Nordisk is also developing a pill version of this medication.
It is important to understand that similar to diabetes and blood pressure medications, anti-obesity medications only work if taken chronically. If the medication is stopped, study participants typically regained the lost weight.
The new weight loss medication Wegovy™ should be available at retail pharmacies on or around June 17th, 2021. So why weight? Now is a great time to call your health insurance company and see if they will cover Wegovy™. Although the price has not been announced, we expect the price to be around $25 / month for those with insurance coverage (similar to Saxenda), or for those without, over $1,000 / month.
*Wegovy™, a glucagon-like peptide-1 (GLP-1) receptor agonist, is indicated as an adjunct to a reduced calorie diet and increased physical activity for chronic weight management in adults with obesity (BMI ≥30 kg/m2), or overweight (BMI≥27 kg/m2) with at least one weight related comorbidity.
