Rybelsus is the tablet form of semaglutide, the same active substance as Ozempic and Wegovy. It is the first and only oral GLP-1 receptor agonist in the world and is manufactured by Novo Nordisk. The tablet is licensed for type 2 diabetes; in the Netherlands it is sometimes prescribed off-label for weight loss in obesity.

What is the difference between Rybelsus and Ozempic?

Rybelsus is a tablet, Ozempic is a weekly injection. Both contain semaglutide. The injection is more effective because the active substance is absorbed better (subcutaneous vs oral). Rybelsus requires a strict fasting protocol (take 30 minutes before eating, with no more than 120 ml of water) to guarantee sufficient absorption.

How much does Rybelsus cost in the Netherlands?

Rybelsus tablets cost approximately €110 to €170 per month depending on the dose (3 mg, 7 mg or 14 mg). For type 2 diabetes it is usually reimbursed by basic health insurance. For off-label use in obesity there is no reimbursement and you pay the full amount yourself.

How much weight can you lose with Rybelsus?

In clinical studies, 14 mg Rybelsus led to approximately 5 to 8% weight loss in 6 months, considerably less than injections (Ozempic 1 mg: ~10%, Wegovy 2.4 mg: ~15%, Mounjaro 15 mg: ~20%). Rybelsus is therefore less powerful than injections, but it is an option for patients with a fear of needles.

What are the side effects of Rybelsus?

The most common side effects are nausea (15-20%), diarrhoea (10%), abdominal pain and vomiting. These are comparable to other GLP-1 medication and occur mainly during the titration phase. Rare but serious risks: pancreatitis, gallstones and (theoretically) thyroid tumours (absolutely contraindicated with a family history of MTC, medullary thyroid tumours).

What is Rybelsus?

Rybelsus is the first and only oral GLP-1 receptor agonist available worldwide. It contains semaglutide, exactly the same active substance as Ozempic and Wegovy, but in tablet form. The tablets are manufactured by Novo Nordisk and are licensed for the treatment of type 2 diabetes.

Developing an oral GLP-1 was long considered technically impossible because the molecule is broken down in the stomach. Novo Nordisk solved this by combining semaglutide with SNAC (salcaprozate sodium), an absorption enhancer that gives the tablet a protected micro-environment in the stomach. This also explains why Rybelsus has to be taken so precisely on an empty stomach.

In the Netherlands, Rybelsus is licensed for type 2 diabetes, not for weight loss. Some doctors prescribe it off-label for obesity; in that case there is no reimbursement from basic health insurance and you pay for it yourself.

Dosing schedule

Rybelsus is built up in three steps to minimise side effects. Each dose is maintained for at least 30 days before you move up.

Month 1

3 mg

Starting dose. The aim is to get used to it, not weight loss.

Months 2-3

7 mg

Therapeutic dose. First effects on appetite and weight become visible.

Month 4+

14 mg

Maximum dose. Full effect on appetite suppression and blood sugar.

Important dosing protocol

• Take on an empty stomach immediately after waking, before you eat, drink or take other medication
• No more than 120 ml of water (half a mug)
• Wait at least 30 minutes before you take or eat anything else
• Do not crush or split — the tablet works through its structure

This protocol is stricter than for many other medications. If you do not follow it, absorption drops below 1% and the treatment does not work.

Rybelsus versus injections

The big question: do you choose a daily tablet or a weekly injection? It depends on your goals and preference.

	Rybelsus	Ozempic	Wegovy
Form	Tablet, daily	Injection, once a week	Injection, once a week
Maximum dose	14 mg	2 mg	2.4 mg
Average weight loss	5-8%	10-12%	15-17%
Indication NL	Type 2 diabetes	Type 2 diabetes	Obesity
Dosing protocol	Strictly fasting	Flexible	Flexible
Cost/month	€110-170	€106-190	€140-190
Reimbursement obesity	No (off-label)	No (off-label)	Sometimes (GVS criteria)

Choose Rybelsus if: you cannot tolerate or do not want injections, your primary goal is diabetes control, or you want milder appetite suppression to make smaller changes.
Choose an injection if: maximum weight loss is the priority, you would find the strict Rybelsus dosing protocol hard to keep up, or if Wegovy is reimbursed in your case and is therefore cheaper.

Side effects and risks

Side effects are comparable to other GLP-1 medication and occur mainly during the titration phase. In most patients they disappear within 4 to 8 weeks.

Common (10-25%)

Nausea
Diarrhoea or constipation
Abdominal pain, bloating
Decreased appetite

Rare but serious

Pancreatitis (inflammation of the pancreas)
Gallstones or cholecystitis
Worsening of retinal damage in diabetes
Suspected MTC with a family history

Rybelsus tablets: cost, reimbursement and how to buy

Rybelsus is available in 3 mg, 7 mg and 14 mg tablets (30 per box). The pharmacy price per month varies by dose:

3 mg (starting phase, first month): approximately €110 — €130 per box of 30
7 mg (low maintenance): approximately €130 — €155 per box
14 mg (maximum maintenance): approximately €145 — €175 per box

Reimbursement for type 2 diabetes: Rybelsus is licensed on the Dutch market for type 2 diabetes and is included in the Medicines Reimbursement System (GVS). Basic health insurance reimburses it subject to conditions, usually once metformin proves insufficient.

Reimbursement for obesity without diabetes: off-label use (for weight loss only, without a type 2 diabetes diagnosis) is not reimbursed by basic health insurance. Some supplementary policies offer partial reimbursement of up to €300-€500 per year. Our BIG-registered doctor assesses whether reimbursement is possible.

How to buy Rybelsus? Only on prescription from a Dutch BIG-registered doctor. At Go Leaner you receive a personal prescription after a comprehensive intake (including blood tests and BMI measurement). You then collect it from a Dutch pharmacy or have it delivered discreetly to your home via our partner pharmacy.

Dosing protocol and experiences with Rybelsus

The effectiveness of Rybelsus depends entirely on the strict fasting protocol. Patients who do not stick to these rules often achieve only 30-50% of the potential effectiveness.

How to take Rybelsus correctly:

Immediately after waking, on a completely empty stomach (no coffee, tea or water in the 30 minutes before)
Swallow the tablet whole with no more than 120 ml of water (do not chew or break it)
Wait at least 30 minutes before you eat, drink or take other medication
Taking it at the same time each day helps build the habit and keeps absorption consistent

What patients typically experience in the first 3 months:

Weeks 1-2: mild nausea in the mornings, reduced appetite already noticeable
Weeks 3-4: most gastrointestinal complaints ease, weight loss starts (~1-2 kg)
Months 2-3: stable pattern, appetite significantly suppressed, on average 3-5% weight loss at the 14 mg dose
Month 6: most patients have lost 5-8% of their starting weight

When to switch to injections? If weight loss stalls after 3-6 months on Rybelsus 14 mg, or side effects become unmanageable, your treating doctor may advise switching to Ozempic, Wegovy or Mounjaro for a stronger effect.

Considering Rybelsus at Go Leaner?

Our BIG-registered doctors assess whether oral semaglutide suits your situation, or whether an injection would be more effective. No questionnaire-only prescriptions: in-person intake, blood tests and at least 6 months of monitoring.
