How to get a prescription for oral Wegovy in Spain: BMI requirements, steps and timescales

To get a prescription for oral Wegovy in Spain, a doctor has to assess you first. If you meet the criteria in the summary of product characteristics (SmPC), they can write you a private prescription. The SmPC approves it for adults with a BMI of 30 or more, or a BMI from 27 to under 30 with at least one weight-related condition. Any pharmacy can dispense it with that prescription, but you pay the full price because the Spanish National Health System (Seguridad Social) doesn't fund it.

Wegovy tablets are oral semaglutide made by Novo Nordisk. CIMA, the register of the Spanish Agency of Medicines and Medical Devices (AEMPS), lists four packs of 30 tablets (1.5, 4, 9 and 25 mg). As of 5 November 2026, all four are prescription-only medicines and on the market in Spain.

What does the SmPC require before oral Wegovy can be prescribed?

Section 4.1 of the SmPC approves Wegovy tablets for weight loss and weight maintenance in two groups of adults, alongside a reduced-calorie diet and more physical activity:

• Obesity: a BMI of 30 kg/m² or more. No other condition is needed.
• Overweight: a BMI from 27 to under 30 kg/m², as long as there is at least one weight-related comorbidity.

The SmPC gives these comorbidities as examples: blood sugar problems (prediabetes or type 2 diabetes), high blood pressure, dyslipidaemia (abnormal cholesterol or triglycerides), obstructive sleep apnoea and cardiovascular disease. The list isn't complete. The prescribing doctor decides whether a particular condition counts.

The indication covers adults only, and the SmPC says there are no data in under-18s. Below these BMI thresholds, use falls outside the approved indication, even if you'd like to lose a few kilos.

How do you work out your BMI to see whether you meet the minimum?

The World Health Organization defines body mass index as your weight in kilograms divided by your height in metres squared: BMI = weight (kg) / height² (m²). For adults, the WHO counts a BMI of 25 or more as overweight and 30 or more as obesity. The Wegovy SmPC sets its own entry point for overweight at 27.

Here's an example for someone who is 1.70 m tall. Their height squared is 1.70 × 1.70 = 2.89. At 90 kg, their BMI is 90 / 2.89 = 31.1, which is in the SmPC's obesity range. At 80 kg, their BMI is 80 / 2.89 = 27.7. That's in the 27 to 30 band, so they would only qualify if they also had a condition such as high blood pressure or prediabetes. At 75 kg, their BMI drops to 26.0, which is below both thresholds.

BMI is a screening figure, not a full diagnosis. The WHO itself points out that waist circumference is also useful for assessing excess weight.

Who can prescribe oral Wegovy, and why on a private prescription?

Article 79.1 of Spain's Law on Guarantees and Rational Use of Medicines (Royal Legislative Decree 1/2015) says only doctors, dentists and podiatrists can prescribe prescription-only medicines, each within their own field. For a weight-management medicine, that means a doctor registered with a Spanish medical college (médico colegiado). CIMA classes it as a prescription-only medicine and doesn't restrict it to hospital use. Any doctor who carries out the assessment can prescribe it, whether a GP, an endocrinologist or another specialist.

Under Article 3 of Royal Decree 1718/2010 on medical prescriptions, a private prescription must include the doctor's name, medical registration number and signature, among other details. Article 14 of the same decree says an electronic prescription can be dispensed at any pharmacy in Spain.

Why doesn't the Spanish National Health System fund oral Wegovy?

In Spain, public money only pays for a medicine if the Ministry of Health issues a formal resolution adding it to public pharmaceutical coverage. Article 92 of the Law on Guarantees says funding is selective. It weighs therapeutic value, cost-effectiveness and the impact on public spending, among other criteria.

BIFIMED, the Ministry's funding database, lists all four Wegovy tablet packs as «No financiado por resolución» (not funded, by formal resolution) from 1 September 2026. It also marks both the obesity indication and the overweight-with-comorbidity indication as «No incluida» (not included). In practice, Wegovy tablets are dispensed on prescription and you pay the full price.

Rybelsus is different. It's the other oral semaglutide, approved only for type 2 diabetes and funded with special authorisation (visado) in specific cases. We cover it in the price of Rybelsus per dose and per month.

What does the doctor check before prescribing it?

The SmPC has only one contraindication: allergy to semaglutide or to any of the excipients. Everything else is a warning that the doctor weighs against your medical history. That's why the assessment involves more than checking your BMI:

• Pancreatitis: extreme caution if you've had it before. If it's confirmed during treatment, the medicine is not restarted.
• Type 2 diabetes: it doesn't replace insulin. Taking it with sulphonylureas or insulin raises the risk of hypoglycaemia, and it isn't recommended if you have uncontrolled diabetic retinopathy.
• Kidneys and liver: it isn't recommended in severe renal impairment (glomerular filtration rate below 30 ml/min/1.73 m²) or severe hepatic impairment.
• Digestive system: it isn't recommended in severe gastroparesis, and nausea, vomiting or diarrhoea can cause dehydration.
• Not studied: type 1 diabetes, class IV heart failure, or use alongside other weight-management products.
• Pregnancy and breastfeeding: it isn't used in either case. If you're planning a pregnancy, the SmPC says to stop it at least two months beforehand.
• General anaesthesia or deep sedation: there have been cases of pulmonary aspiration because the stomach empties more slowly. The SmPC asks for this to be taken into account beforehand.

The doctor also checks what medicines you already take. The SmPC says to check thyroid function in people taking levothyroxine and to monitor INR in people taking warfarin or acenocoumarol. You take the tablet on an empty stomach and wait 30 minutes before eating or taking other oral medicines, so the doctor also checks whether that routine fits with your other treatments.

What are the steps from appointment to pharmacy, and how long does it take?

• Medical assessment: weight, height, BMI, related conditions, medical history and current medicines. This can be done in person or by telemedicine, but always with a registered doctor. If you're doing it online, read what to expect from a weight-loss clinic.
• Private prescription: if the doctor thinks it's appropriate, they write the prescription on paper or electronically for a specific pack. Under the SmPC, you start on 1.5 mg a day for four weeks, then move up in steps to 4, 9 and 25 mg, staying at least four weeks on each. Each step is a different pack.
• Pharmacy: a paper prescription is valid for ten calendar days from the date it's written (or from the planned dispensing date, if one is given). An electronic prescription is valid for ten days for the first dispensing. As a general rule, each paper prescription covers a single pack, and no prescription can cover more than three months of treatment (Articles 5.5 and 13 of Royal Decree 1718/2010).
• Payment: because it isn't funded, the price is not regulated. The press has reported €236.20 for the box of 30 × 25 mg tablets, but no official price has been published. We couldn't find prices for the starting doses.

The SmPC sets the timescale. With at least four weeks at each of the 1.5, 4 and 9 mg steps, it takes at least 12 weeks to reach the 25 mg maintenance dose. The doctor decides each dose change, so follow-up is part of the treatment.

Can you buy oral Wegovy without a prescription or online?

No. Article 3.5 of the Law on Guarantees bans the online or mail-order sale of prescription-only medicines. Royal Decree 870/2013 only allows distance selling of non-prescription medicines, through the website of an authorised pharmacy with a pharmacist responsible.

On 3 September 2025, the AEMPS, together with the EMA and the network of European medicines agencies, warned of a sharp rise in illegal products sold as semaglutide, liraglutide or tirzepatide on fraudulent websites and social media. These products may not contain the active ingredient they claim to, and may contain other harmful substances. We explain this in how to get these treatments legally and safely.

Key points

A prescription for oral Wegovy depends on three things you can check. First, a BMI of 30 or more, or 27 or more with a related condition. Second, an assessment by a registered doctor who reviews the contraindications and warnings. Third, a private prescription: if it's on paper, you have to take it to a pharmacy within ten days, and you pay the full price. For people in Spain who want to lose weight with medical support, there is medical weight-loss treatment available today. It involves an assessment first, a prescription from a registered doctor where appropriate, and ongoing follow-up. You can:
