Ozempic is the brand name of a semaglutide injection that comes under the drug class called antidiabetics or Glucagon-like Peptide-1 Agonists.  It is usually prescribed to treat Diabetes Mellitus. Semaglutides are GLP-1 receptor agonists also called incretin mimetics.

These work by enhancing insulin secretion in your body and increasing glycemic control. Good glycemic control is necessary to balance blood sugar levels and that is where the importance of semaglutide comes to the fore.

The Food and Drugs Administration approved Ozempic for treating type 2 diabetes in 2017 in the United States. It is currently used as an off-label for aiding in weight loss for patients who suffer from obesity or are overweight. 

What is Ozempic used for?

Ozempic was initially approved to balance glycemic control in patients who suffer from type 2 diabetes. It also can be used to decrease the onset of cardiovascular issues. But at the same time, the Food and Drugs Association has made it clear that it is not a substitute for insulin.

So Ozempic can not be prescribed for patients with type 1 diabetes mellitus. Also, they have advised that it should not be used for patients who have a history of pancreatitis. 

How does it work?

When one takes Ozempic, it balances the blood sugar levels and thereby decreases the appetite of patients. It instigates insulin secretion in your body and reduces glucagon release. Being a GLP-1, Glucagon-like-Peptide-1, Ozempic increases insulin sensitivity in the body.

That is how they primarily treat diabetes. The intake of Ozempic can reduce your appetite and contribute to a feeling of fullness. That is how it can aid in weight loss. Studies have shown that the intake of Ozempic can also decrease sugar cravings. 

How to use Ozempic?

Ozempic comes as a subcutaneous injection that should be taken once a week for 4 weeks. Each injection contains 0.25mg of Ozempic and it is ideal for the initial treatment. Your doctor will suggest an additional 0.5mg along with the Ozempic after 4 weeks.

This is to control the glycemic levels in your body and if it is not limited by this dosage, doctors will prescribe increasing it to 1 mg weekly.
