Are Weight Loss Injections Safe? Risks, Benefits, and Myths

You're looking for information on weight loss injections, and specifically, how to get a prescription online in the EU. You've come to the right place.

4. Print the PDF or show it on your phone — present it at **any pharmacy in the EU** to collect your medication.

Who qualifies for weight loss injections

When you consult with an EU-licensed doctor for a weight loss injection prescription, they will carefully assess your medical history and current health status. Typically, safe and effective use of these medications (like semaglutide or tirzepatide) is 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 high cholesterol. The doctor will look for any contraindications, which are conditions that would make the medication unsafe for you, such as a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. They will also consider other factors to ensure the treatment is appropriate for your specific needs.

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

Weight loss injections, primarily GLP-1 receptor agonists like semaglutide (Wegovy) and tirzepatide (Mounjaro), work by mimicking natural hormones in your body. These hormones regulate appetite and blood sugar. When you take these medications, they slow down how quickly food leaves your stomach, making you feel fuller for longer. They also act on the brain to reduce your appetite and cravings. This leads to a natural reduction in your calorie intake and, over time, significant weight loss. It's important to understand that these injections are not a 'magic bullet'. They are most effective when combined with healthy eating habits and regular physical activity. Realistic timelines for noticeable weight loss vary, but consistent use alongside lifestyle changes typically yields results over several months. You won't lose 10 kg overnight, but you can expect a steady, sustainable reduction in weight if the treatment is appropriate for you.

Side effects and when to stop

Like all medications, weight loss injections can have side effects. The most common ones are gastrointestinal, including nausea, vomiting, diarrhea, and constipation. These are usually mild to moderate and often improve as your body adjusts to the medication. Less common, but more serious, side effects can include pancreatitis, gallbladder problems, or kidney issues. Your doctor will discuss all potential side effects with you and monitor your progress. It's crucial to seek immediate medical attention if you experience severe abdominal pain, persistent vomiting, or signs of an allergic reaction. Your doctor will advise you on when it might be necessary to stop treatment, especially if side effects are severe or if the medication is not producing the desired results after a certain period.
