Rybelsus (oral semaglutide tablets)
Updated over a week ago

Rybelsus is a prescription-only-medicine. Our clinicians review each treatment request on an individual basis, and prescriptions are subject to a clinical decision after completing our online consultation. This page is only intended for those who have completed an online consultation and have been prescribed Rybelsus.

We'd like to give you some important information before you start taking Rybelsus. It’s also recommended to read the patient information leaflet to understand how the medication works, what to expect, and potential side effects and how to manage them.

What is Rybelsus and how does it work?

Rybelsus is a medication that is licensed for type 2 diabetes patients. The active ingredient in Rybelsus is called semaglutide. Semaglutide mimics the hormone glucagon-like peptide-1 (GLP-1), which is naturally released in your gut after you eat and acts on GLP-1 receptors. Because of this, semaglutide is also known to be a GLP-1 receptor agonist. As a GLP-1 receptor agonist, semaglutide prompts the body to produce more insulin, which in turn reduces blood sugar levels. It also interacts with receptors in the brain, reducing appetite which can lead to weight loss. A prescription for Rybelsus outside of its licensed use is a clinical decision based on the specific needs and factors of each individual patient.

How to take Rybelsus

Rybelsus should be taken on an empty stomach at any time of the day. The tablet should be swallowed whole with a sip of water (up to half a glass of water equivalent to 120 ml). Don’t crush, split or chew the tablet as that might affect the effectiveness of the medication. After taking the tablet, wait at least 30 minutes before eating or drinking or taking other oral medicinal products.

Your dose of Rybelsus will gradually be increased each month until you reach your maintenance dose.

  • Your dose of Rybelsus will gradually be increased each month until you reach your maintenance dose. You can find the dosage information on the label of your medication box or within the treatments section of your Numan account page.

  • If you are unclear on the dose, please speak to a clinician.

  • If you feel you are not experiencing the weight loss you expected, or are experiencing an increase in appetite, contact our clinical team, who will review your dosage. You can contact our clinical team on [email protected]. Alternatively, you can contact your health coach or clinician via the coaching section in the Numan app.

Don’t take Rybelsus…

  • If you are allergic to semaglutide or any of the other ingredients in the medication.

  • If you have diabetes (type 1 or type 2), controlled with medication.

  • Together with insulin or insulin secretagogue medications (e.g. sulfonylurea), semaglutide lowers blood sugar and can cause hypoglycemia. The risk of hypoglycemia is increased when semaglutide is used in combination with insulin or insulin secretagogue medications.

  • If you are taking other GLP-1 agonists (semaglutide, liraglutide, dulaglutide, eventide or lixisenatide). GLP-1 agonists lower blood sugar and can cause hypoglycemia.

  • If you develop diabetic ketoacidosis (a complication of diabetes with high blood sugar, breathing difficulty, confusion, excessive thirst, a sweet smell to the breath or a sweet or metallic taste in the mouth).

  • Together with other prescription, over-the counter, or herbal weight loss products.

  • If you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC).

  • If you have or have previously had acute pancreatitis.

  • If you have or have had problems with your pancreas.

  • If you are pregnant or think you might be pregnant.

  • If you are breastfeeding.

  • If you have an eating disorder such as anorexia nervosa or bulimia nervosa.

  • If you have congestive heart failure.

  • If you have kidney disease or are on dialysis.

  • If you have liver problems.

  • If you have had bariatric surgery.

If you are on any of the following medications, please speak to your GP before starting treatment:

  • Levothyroxine which is used for thyroid disease. You might need to check your thyroid levels when taking Rybelsus together with levothyroxine.

  • Warfarin or similar medicines taken by mouth to reduce blood clotting (oral anticoagulants). You may need frequent blood tests to check how quickly your blood clots.

What to do if you forget or miss a dose

If you forget or miss a dose, skip the missed dose for that day. The next day, take your dose as normal. Never double up tablets to account for missed dosages.

If you miss more than one dose, please contact a Numan clinician.

What to do if you take more Rybelsus than you should

If you take more Rybelsus than you should, contact your clinician straight away. You may get side effects such as feeling sick (nausea).

Side-effects of Rybelsus

Like all medicines, Rybelsus can cause side effects, although not everybody gets them. Most patients find that the side effects resolve with time, once your body is accustomed to the medication. If your side effects are not resolving, please speak to one of our clinicians who can advise you on next steps.
