Can I buy Rybelsus for weight loss in the UK?

Generally, you'll struggle to get a prescription for Rybelsus for weight loss in the UK.

Here we’ll talk you through what Rybelsus is, how it works for diabetes, and the process of it being prescribed.

What is Rybelsus?

Rybelsus is a tablet you take once a day to control your blood sugar for type-2 diabetes. The active ingredient in Rybelsus is semaglutide, the same active ingredient in the weight-loss medication Wegovy. It’s also available as another type-2 diabetes treatment called Ozempic.

Before Rybelsus, the only way to take semaglutide was as an injection (Wegovy and Ozempic). The pharmaceutical company Novo Nordisk developed a tablet form to target patients who found it difficult to use injections. It was the first GLP-1 receptor agonist to become available globally.

It’s used for type-2 diabetes because the active ingredient works in several ways to help lower your blood sugar levels. Its main job is to reduce insulin resistance, but it also has the added bonus of curbing your appetite, which can help you to lose weight because you don’t feel as hungry as often. Weight loss can be good for patients with type-2 diabetes, as it tends to go hand-and-hand with lower blood sugar levels and also improves overall cardiovascular health.

How does Rybelsus work?

Semaglutide acts like a hormone called GLP-1 (glucagon-like peptide-1) that our bodies naturally produce. Rybelsus activates receptors in your body called GLP-1 receptors, which are found in different parts of your body, like the pancreas, brain, and stomach.

Rybelsus tells your pancreas to release more insulin, a hormone that helps lower blood sugar levels after you eat. It also sends signals to your brain to reduce your appetite and make you feel fuller for longer. This can help you eat less and make healthier food choices, like sticking to a low-calorie diet. Rybelsus can slow down the emptying of food from your stomach. This means that the food stays in your stomach for a longer time, which can make you feel satisfied and help control your appetite.

What dose of semaglutide does Rybelsus come in?

Rybelsus comes in three strengths of semaglutide for type-2 diabetes. The starting dose of Rybelsus is one 1.5 mg tablet once a day, for one month. This will then increase to one 4 mg tablet a day. If a 4 mg dose isn’t enough to manage your blood sugar effectively, your clinician may increase your dose to 9 mg once a day.

What other medications use the active ingredient semaglutide?

Both Wegovy and Ozempic contain semaglutide as their active ingredient. While Wegovy is specifically licensed for weight loss, Ozempic is only approved for treating type-2 diabetes. 

Both medications are administered through injections once a week and are available in different dosages. Typically, patients start with the lowest dose and gradually increase it to a manageable level. Wegovy comes in six strengths: 0.25mg, 0.5mg, 1mg, 1.7mg, 2.4mg, and 7.2mg, while Ozempic is available in three: 0.25mg, 0.5mg, and 1mg.

Who can use Rybelsus?

Rybelsus has been approved as a suitable treatment for people who have type-2 diabetes and have high blood sugar. It’s best used alongside a low calorie diet and exercise regimen or other diabetic treatments to help keep your blood sugar levels under control. Rybelsus can be used on its own but this is usually only when you can’t tolerate or take metformin due to conflicting medications.

Most semaglutide treatments for weight loss are used for around two years, and they should be used alongside a low-calorie diet and exercise. Sometimes they can be used for longer than this, but this is something you’d need to discuss with your clinician.

Will Rybelsus help me lose weight?

Will Rybelsus help me lose weight?

Rybelsus has been clinically proven to aid weight loss. In a random, placebo-controlled trial called OASIS 1, oral semaglutide was assessed for the treatment of non-diabetic overweight adults. The results showed that the group taking the oral pill experienced an average weight loss of 15.1%, while the placebo group only lost 2.4%.  

Where can I buy Rybelsus for weight loss?

You can’t simply buy Rybelsus for weight loss in the UK. You can only get it on prescription, and only if you’ve been diagnosed with type-2 diabetes. 

But if you do want to use a tablet treatment for weight loss rather than an injectable GLP-1, you might want to try the Wegovy pill. You take the tablets daily, and like the injections, it works by suppressing hunger cues and slowing down the rate your stomach empties.

Can I get Rybelsus as an injection?

Rybelsus is unique in that it’s the first oral GLP-1 receptor agonist, and it was created for that purpose: to provide an alternative to the injections that were already on the market. If you’re interested in taking semaglutide as a once-weekly injection instead of a daily tablet, Wegovy may be an option for you. Wegovy is the only MHRA-approved treatment for weight loss, and it’s available as a pre-filled pen with doses of 0.25mg, 0.5mg, 1mg, 1.7mg, 2.4mg, and 7.2mg.

Can I get Rybelsus without a prescription?

Can I get Rybelsus without a prescription?

Like other semaglutide medications, you will need a prescription for Rybelsus. It’s not available over-the-counter. The prescriber will want to make sure you’re already taking it for diabetes. Answer a few questions using our online consultation, and our expert clinicians can write a one-off Rybelsus prescription for you, as well as show you other suitable options too.
