Rybelsus (Semaglutide)

What is Rybelsus (Semaglutide)?

Rybelsus is an oral medication that contains semaglutide, a GLP-1 receptor agonist (glucagon-like peptide-1). It is primarily used to manage type 2 diabetes in adults by helping control blood sugar levels. Unlike many GLP-1 receptor agonists that are injectable, Rybelsus is taken orally, making it the first oral GLP-1 medication approved for diabetes management.

What are the Uses of Rybelsus?

Rybelsus is prescribed for:

• Type 2 diabetes mellitus: To improve glycemic control in adults.

• Cardiovascular risk reduction: In some cases, it may help reduce the risk of major cardiovascular events in patients with both type 2 diabetes and established heart disease (though this is more commonly associated with injectable forms like Ozempic).

• Weight management (off-label use): Semaglutide has shown benefits in promoting weight loss, though Rybelsus is not FDA-approved specifically for obesity.

Note: Rybelsus is not recommended for treating type 1 diabetes or diabetic ketoacidosis.

How Does Rybelsus Work?

Rybelsus (semaglutide) mimics the action of the GLP-1 hormone, which helps:

• Stimulate insulin secretion in response to high blood glucose

• Reduce glucagon secretion, which lowers glucose production by the liver

• Slow gastric emptying, reducing the rate of glucose absorption

• Promote satiety, decreasing food intake

How to Take Rybelsus?

• Take once daily, ideally at the same time each day.

• Take with a small amount of water (no more than 4 ounces) on an empty stomach.

• Wait at least 30 minutes before eating, drinking (other than water), or taking other medications.

• Swallow the tablet whole—do not split, crush, or chew.
