They’ll monitor how your body responds to the drug. If necessary, your doctor may increase your dosage to 14 mg once daily after you’ve taken the 7-mg daily dose for at least 30 days. Your doctor may adjust your dosage if needed to better manage your condition.

Below is information on commonly asked questions about Rybelsus.

Can Rybelsus be used for weight loss? If so, what is the dosage for weight loss?

Rybelsus is not approved by the Food and Drug Administration (FDA) as a weight loss medication. However, studies have shown that semaglutide can cause weight loss when used with diet and exercise changes. Semaglutide is the active ingredient in Rybelsus.

Certain factors, such as changes in your diet and exercise regimen, may cause weight loss during Rybelsus treatment. Keep in mind that Rybelsus is prescribed in combination with a balanced diet and exercise to manage blood sugar levels in certain adults with type 2 diabetes.

Weight loss may also happen due to side effects of the drug, such as:

  • nausea
  • vomiting
  • loss of appetite
  • diarrhea

If your doctor prescribes Rybelsus for weight loss, it will be an off-label use of the drug. (Off-label use means a drug is used for a purpose other than those it’s approved for.) In this case, your doctor will discuss a dosage of Rybelsus for weight loss with you.

Note: A prescription medication called Wegovy is approved for long-term weight management. It contains semaglutide, the same active ingredient that’s in Rybelsus. If you’re interested in learning more about Wegovy, ask your doctor.

Does Rybelsus have recommended dosing instructions?

Yes, your doctor will likely provide a dosing guide when they prescribe Rybelsus.

Typically, you’ll start with a low dose of Rybelsus and take this dose for the first 30 days. Then your doctor may increase your dose. After at least another 30 days, they may increase your dose again. This depends on how your body responds to the treatment.

Your doctor and pharmacist will also provide dosing instructions on how to take the drug. It’s important to take Rybelsus at least 30 minutes before your first food or drink of the day. You should take the drug with a small amount (4 ounces) of water. This ensures that Rybelsus works the way it’s supposed to in your body.

See the “How to take Rybelsus” section below for more dosing instructions. You can also refer to the drug’s prescribing information.

If I have renal (kidney) problems, will I need a renal dosing adjustment for Rybelsus?

No, Rybelsus doses typically don’t require adjustments in people with kidney disease. In clinical trials of the drug in people with kidney disease, there were no differences in how Rybelsus worked in the body. These trials included people with end stage renal disease.

Tell your doctor if you have kidney problems before you begin treatment with Rybelsus. Your doctor will monitor your kidney function while you’re taking the medication. This is because the drug can cause new or worsening kidney problems. For more information on side effects of Rybelsus, see this article.

If you miss a daily dose of Rybelsus, skip the missed dose and continue with your usual dosing schedule the next day. Do not take two doses of Rybelsus at one time to make up for the missed dose.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.

The Rybelsus dosage your doctor prescribes will depend on several factors. These include:

  • the severity of your condition
  • other medications you may be taking

Rybelsus comes as oral tablets that you’ll swallow. You’ll take it once per day. You should take the drug with a small amount (4 ounces) of water.

It’s important to take Rybelsus 30 minutes before you eat, drink, or take any other medications for the day.

Eating or drinking less than 30 minutes after taking Rybelsus can lower the effectiveness of the drug. This is because food or other types of liquid can affect how Rybelsus works in your body.

Waiting longer than 30 minutes after taking Rybelsus to eat or drink anything can increase the effect of Rybelsus in your body. This could increase your risk of low blood sugar.

Do not chew, cut, or split Rybelsus tablets. Instead, swallow the tablets whole. If you have trouble swallowing tablets, see this article for tips on how to take this form of medication. You can also talk with your doctor or pharmacist.


Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.

If you’re having trouble opening medication bottles, ask your pharmacist about putting Rybelsus in an easy-open container. They also may recommend tools that can make it easier to open bottles.

If you take more Rybelsus than your doctor prescribes, you may develop serious side effects. It’s important that you don’t take more Rybelsus than your doctor advises.

If you take more than the recommended amount of Rybelsus

Call your doctor right away if you believe you’ve taken too much Rybelsus. Another option is to call America’s Poison Centers at 800-222-1222 or use its online tool. If you have severe symptoms, immediately call 911 or your local emergency number, or go to the nearest emergency room.
