How it works — get your Semaglutide prescription in 4 steps

  1. Fill the online medical questionnaire. It takes just 2–3 minutes to provide your medical history and current health status.
  2. A licensed EU doctor reviews your case in private. Our doctors assess your information carefully to determine if Semaglutide is appropriate for you.
  3. If appropriate, you receive a REMPE electronic prescription within 24 hours. This secure, digital prescription is delivered to your private account and by email.
  4. Pick up your medication at any EU pharmacy. Your prescription is valid across the European Union, including Spain, Portugal, Italy, France, and Germany.

Who qualifies for Semaglutide

Our EU-licensed doctors determine if Semaglutide is appropriate for your weight management journey. Generally, they look for specific criteria:

  • BMI (Body Mass Index) of 30 kg/m² or greater (obesity).
  • BMI of 27 kg/m² or greater (overweight) with at least one weight-related comorbidity, such as high blood pressure, type 2 diabetes, 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 kidney disease.

Each case is reviewed individually to ensure your safety and the treatment's effectiveness. The doctor remains the gatekeeper, issuing a prescription only if it's medically appropriate for you.

What Semaglutide actually does (and doesn't do)

Semaglutide is a GLP-1 receptor agonist that helps manage weight by mimicking a natural hormone your body produces. It works by:

  • Reducing your appetite: You feel fuller faster and for longer, leading to reduced calorie intake.
  • Slowing stomach emptying: This contributes to prolonged feelings of fullness and helps control blood sugar levels.
  • Impacting brain signals: It influences the parts of your brain that regulate hunger and satiety, helping to curb cravings.

It's important to understand that Semaglutide is not a magic bullet. It's a tool that supports weight loss when combined with a reduced-calorie diet and increased physical activity. Realistic timelines show that significant weight loss typically occurs over several months, with an average of 15% body weight reduction in clinical trials over 68 weeks. It doesn't guarantee specific results, and individual outcomes vary.

Side effects and when to stop

Like all medications, Semaglutide can cause side effects. Most are mild and temporary, especially during dose escalation. Common side effects include nausea, vomiting, diarrhea, constipation, and abdominal pain. These usually subside as your body adjusts.

However, it’s crucial to be aware of less common but more serious side effects, such as pancreatitis, gallbladder issues, or kidney problems. If you experience severe abdominal pain, persistent vomiting, or signs of an allergic reaction, stop the medication and seek immediate medical attention. Your EU-licensed doctor will discuss these risks with you and monitor your treatment. Always follow your doctor's instructions and report any concerning symptoms.
