If you're searching for a weight loss medication prescription online in the EU, you're in the right place. Hi-Doctor connects you with EU-licensed doctors who can assess your case. Yes, you can get medications like Wegovy (semaglutide), Saxenda (liraglutide), or Mounjaro (tirzepatide) through a licensed EU doctor, here's how. For just €25, an online consultation determines if treatment is appropriate. If approved, you receive a valid REMPE electronic prescription in under 24 hours, accepted at any pharmacy throughout the EU.

How it works — get your weight loss medication prescription in 4 steps

  1. Fill out our quick online medical questionnaire (takes 2–3 minutes) and pay the €25 consultation fee.
  2. An EU-licensed doctor reviews your case individually and in private. If the doctor determines the treatment is NOT appropriate for you, your €25 fee is refunded automatically — no risk to you.
  3. If approved, you receive a REMPE electronic prescription (a downloadable PDF file) directly in your Hi-Doctor account and via email within 24 hours.
  4. Print the PDF or show it on your phone — present it at any pharmacy in the EU (Spain, Portugal, Italy, France, Germany, Netherlands, Belgium, Austria, Ireland, etc.) to collect your medication.

Who qualifies for weight loss medication

Our EU-licensed doctors review each case to ensure the medication is safe and appropriate for you. Generally, eligibility for GLP-1 receptor agonists like Wegovy, Saxenda, or Mounjaro depends on your Body Mass Index (BMI) and overall health. Doctors typically look for:

  • A BMI of 30 or higher (obesity).
  • A BMI of 27 or higher (overweight) with at least one weight-related comorbidity such as type 2 diabetes, high blood pressure, or high cholesterol.
  • No contraindications such as a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), or severe gastrointestinal disease.
  • No current pregnancy or breastfeeding.

The doctor considers your full medical history during the online consultation to make a personalised decision.

What weight loss medication actually does (and doesn't do)

Weight loss medications like semaglutide (Wegovy) and liraglutide (Saxenda) are GLP-1 receptor agonists. They work by mimicking a natural gut hormone that regulates appetite and food intake. This leads to a feeling of fullness, reduced hunger, and slower stomach emptying. Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist, offering a similar but often more potent effect.

These medications are not 'magic pills.' They are tools to support weight loss when combined with diet and exercise. You can expect a gradual, steady weight loss over several months, not sudden dramatic changes. They help you stick to a reduced-calorie diet by making it easier to eat less, but they do not eliminate the need for lifestyle changes. Consistency is key for achieving and maintaining results.

Side effects and when to stop

Like all medications, weight loss treatments can have side effects. Common ones include nausea, vomiting, diarrhoea, constipation, and abdominal pain, especially when starting treatment or increasing the dose. These are usually mild to moderate and often improve over time as your body adjusts. To minimise these, the doctor often recommends starting with a low dose and gradually increasing it.

You should contact a doctor immediately if you experience severe abdominal pain (which could indicate pancreatitis or gallbladder issues), persistent vomiting or diarrhoea leading to dehydration, or signs of an allergic reaction (e.g., swelling of the face, lips, tongue, or throat, difficulty breathing). The doctor will advise you on when to stop treatment, which typically happens if side effects are unmanageable, or if you reach your weight loss goals and discuss a maintenance plan.
