Weight Loss Medication Approval: FDA and EU Regulations

You’re looking for weight loss medication online, and you want to know how to get an electronic prescription in the EU. Yes, you can get a prescription for weight loss medication through a licensed EU doctor, from the comfort of your home. Hi-Doctor offers a discreet, efficient online consultation service. For just €25 every 28 days (cancel anytime) or €35 one-off, an EU-licensed doctor reviews your case. If treatment is appropriate, you receive a valid electronic prescription in under 24 hours, accepted at any pharmacy across the EU.

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

  1. Fill the online medical questionnaire (2–3 minutes) and pay the consultation fee of €25 every 28 days or €35 one-off.
  2. A licensed EU doctor reviews your case in private. If the doctor decides the treatment is not appropriate for you, your payment is refunded automatically, so there is no risk. You pay nothing.
  3. If approved, you receive a valid electronic prescription (a downloadable PDF file) in your Hi-Doctor account and by email within 24 hours.
  4. Print the PDF or show it on your phone and present it at any pharmacy in the EU to collect your medication.

Who qualifies for weight loss medication

When you complete your online medical questionnaire, the doctor reviews your health profile to determine if weight loss medication is appropriate for you. They look for specific criteria, including:

  • Body Mass Index (BMI): Typically, a BMI of 30 or higher (obesity), or a BMI of 27 or higher (overweight) with at least one weight-related comorbidity (e.g., type 2 diabetes, high blood pressure, dyslipidemia).
  • Medical History: The doctor assesses your overall health, existing conditions, and any medications you currently take to ensure the treatment is safe and won't interact negatively.
  • Previous Weight Loss Efforts: They consider your history of diet and exercise interventions to confirm that lifestyle changes alone have not been sufficiently effective.
  • Contraindications: Certain conditions, such as a personal or family history of medullary thyroid carcinoma, Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), or severe gastrointestinal disease, may make you unsuitable for some GLP-1 medications.

The doctor's review ensures your safety and the effectiveness of the treatment plan.

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

Medications like semaglutide (Wegovy) and tirzepatide (Mounjaro) are GLP-1 receptor agonists. They work by mimicking a natural hormone in your body that helps regulate appetite and food intake. This leads to:

  • Reduced Hunger: You feel fuller faster and for longer, leading to a natural decrease in calorie consumption.
  • Slower Gastric Emptying: Food stays in your stomach longer, further contributing to feelings of fullness.
  • Improved Blood Sugar Control: These medications also help regulate blood sugar, which can be beneficial for overall metabolic health.

What they don't do: These medications are not a magic bullet. They are most effective when combined with healthy lifestyle changes, including a balanced diet and regular physical activity. You won't see results overnight; significant weight loss typically occurs over several months, with average losses of 15% to 22% of body weight over 68–72 weeks, depending on the specific medication.

Side effects and when to stop

Like all medications, weight loss treatments can have side effects. Most are mild and temporary, especially during the initial weeks as your body adjusts to the medication. Common side effects include:

  • Nausea
  • Vomiting
  • Diarrhea or constipation
  • Abdominal pain
  • Headache

When to contact your doctor or stop the medication:

  • If you experience severe abdominal pain, especially if it radiates to your back (this could indicate pancreatitis, a rare but serious side effect).
  • If you have persistent vomiting or diarrhea leading to dehydration.
  • If you notice signs of a severe allergic reaction (e.g., swelling of the face or throat, difficulty breathing).
  • If you develop symptoms of gallbladder problems (e.g., severe pain in your upper right abdomen, fever, jaundice).

Always discuss any concerning side effects with your Hi-Doctor EU-licensed doctor through the private chat in your account. They will advise you on whether to continue, adjust your dose, or stop the medication.
