Who Should NOT Use Weight Loss Injections? Important Considerations

If you're searching for information on weight loss injections like GLP-1 agonists (e.g., semaglutide, liraglutide, tirzepatide), you're likely wondering if they're right for you and how to get a prescription online in the EU. This article explains who should not use these medications, and how you can get an online consultation with an EU-licensed doctor for just €25. If the doctor finds the treatment appropriate, you'll receive a digital prescription in under 24 hours, valid at any pharmacy across the EU. If not, you get your money back — no risk.

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

  1. Fill the online medical questionnaire (2–3 minutes) and pay the €25 consultation fee.
  2. A licensed EU doctor reviews your case in private. If the doctor decides the treatment is NOT appropriate, your €25 is refunded automatically — no risk, you pay nothing.
  3. If approved, you receive a REMPE electronic prescription (PDF file) in your Hi-Doctor account and by email within 24 hours.
  4. Print the PDF or show it on your phone — present it at any pharmacy in the EU to collect the medication.

Who qualifies for weight loss injections

Our EU-licensed doctors assess each patient individually to determine if weight loss injections are a safe and effective option. Generally, these medications are considered for adults with a Body Mass Index (BMI) of 30 or higher (obesity), or a BMI of 27 or higher (overweight) with at least one weight-related comorbidity such as type 2 diabetes, high blood pressure, or dyslipidemia. The doctor will look for a comprehensive medical history, including existing conditions and current medications, to ensure your safety and suitability for treatment.

What weight loss injections actually do (and doesn't do)

Weight loss injections, primarily GLP-1 receptor agonists, work by mimicking natural hormones that regulate appetite and blood sugar. They slow gastric emptying, helping you feel fuller for longer, and reduce food cravings. This leads to a decrease in calorie intake and, typically, a gradual, sustainable weight loss when combined with diet and exercise. These medications are a tool to support weight management, not a magic bullet. They do not replace healthy eating and physical activity, and results vary. Expect a gradual process, not a quick fix.

Side effects and when to stop

Like all medications, weight loss injections can have side effects. Most commonly, patients experience mild gastrointestinal issues such as nausea, vomiting, diarrhoea, or constipation, especially when starting treatment or increasing the dose. These usually subside over time. More serious, though rare, side effects can include pancreatitis, gallbladder problems, kidney issues, or severe allergic reactions. It's crucial to report any persistent or severe side effects to your doctor immediately. Your Hi-Doctor physician will guide you on when to stop or adjust treatment based on your individual response and any adverse reactions.
