GLP-1 receptor agonists are a popular class of medications used to manage blood sugar levels in adults with type 2 diabetes. While these treatments were once only available as shots, medical advances have introduced convenient GLP-1 pills.
There are now two primary oral semaglutide options approved by the FDA for use in the United States: Rybelsus and the Wegovy pill. These medications allow patients to get the benefits of GLP-1 therapy without needing daily or weekly injections.
These medications work by mimicking a natural hormone that helps regulate both appetite and blood sugar. They are often prescribed for people who need strong glucose control or help with chronic weight management.
Indications for use
The FDA has approved GLP-1 pills for two distinct primary purposes depending on the brand. It is important to understand which version is appropriate for a specific health goal.
-
Type 2 diabetes: Oral semaglutide (Rybelsus) is specifically approved to improve blood sugar control in adults with type 2 diabetes alongside diet and exercise.
-
Chronic weight management: The Wegovy pill is approved for adults living with obesity (BMI of 30 or higher) or those who are overweight (BMI of 27 or higher) with weight-related health issues.
-
Heart health: For adults with established heart disease who are also overweight or obese, the Wegovy pill can reduce the risk of major events like heart attacks and strokes.
Choosing the right medication depends on whether the primary focus is blood sugar regulation or weight loss.
How to take it
To get the full benefit of GLP-1 pills, you must follow the dosing instructions exactly. These medications use a unique technology called SNAC, which protects the drug from stomach acid so your body can absorb it through the stomach lining. Because food can stop this process from working, you must take the pill on an empty stomach.
You should take the tablet the moment you wake up with no more than 4 ounces (120 milliliters) of plain water. After swallowing the tablet, you need to wait at least 30 minutes before eating, drinking anything else, or taking other oral medicines.
Dosing schedule
Your healthcare provider will start you on a low dose to help your body adjust to the medicine. The dosing varies based on the specific medication:
-
For diabetes (Rybelsus): The initiation dose is 3 mg once daily for 30 days, typically increasing to a maintenance dose of 7 mg or a maximum of 14 mg.
-
For weight management (Wegovy pill): The standard daily dose for long-term weight control is 25 mg. Your provider will gradually increase your dose over several weeks to reduce potential stomach issues.
Following this gradual schedule helps ensure the medication is well-tolerated while reaching its effective strength.
Possible side effects
The most common side effects for GLP-1 pills are stomach and digestive issues. Many people experience nausea, vomiting, diarrhea, or constipation, especially when starting the medication or increasing a dose. These symptoms often improve as your body adjusts.
Serious side effects are less common but can include:
-
GLP-1 pills offer an injection-free way to manage type 2 diabetes or support long-term weight loss, depending on the specific medication.
-
Rybelsus is used for blood sugar control, while the Wegovy pill is approved for weight management and can also lower heart attack and stroke risk in certain adults.
-
These pills must be taken on an empty stomach and timed carefully, since eating too soon can prevent the medication from being absorbed properly.
-
Pancreatitis: Painful inflammation of the pancreas that requires medical attention.
-
Gastroparesis: Delayed stomach emptying that can cause bloating and discomfort.
-
Vision changes: Possible worsening of diabetic retinopathy or rare conditions such as NAION that can cause sudden vision loss.
-
Heart safety: Clinical trials have confirmed that oral semaglutide does not increase the risk of major cardiovascular events.
While many of these effects are manageable, you should always report new or worsening symptoms to your doctor.
Contraindications for use
GLP-1 pills are not safe for everyone and carry a boxed warning about thyroid tumors. You should not take these medications if you have a personal or family history of medullary thyroid carcinoma (MTC) or a genetic condition called multiple endocrine neoplasia syndrome type 2 (MEN 2).
Pregnancy is also a reason to avoid this medication. It is recommended to stop treatment at least two months before a planned pregnancy. Breastfeeding is not recommended during treatment because the effects on infants are not fully studied
