Weight Loss Medication Overdose: What You Need to Know

Understanding the risks of weight loss medication, including potential overdose, is crucial for your safety. While medications like GLP-1 agonists (e.g., semaglutide, tirzepatide) can be effective tools for weight management when used correctly, proper guidance is essential. Here's how you can get your weight loss medication prescription online from an EU-licensed doctor, without the clinic visit. Our online consultation is just €25 every 28 days (cancel anytime) or €35 one-off, and if approved, you receive a prescription in under 24 hours, valid at any EU pharmacy.

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, your payment is refunded automatically, so there is no risk.
  3. If approved, you receive a valid 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 and present it at any pharmacy in the EU to collect the medication.

Who qualifies for weight loss medication

EU-licensed doctors review your medical history, BMI, and other health factors to determine if weight loss medication like GLP-1 agonists (semaglutide, tirzepatide) is appropriate for you. They look for specific criteria, such as a BMI typically above 30, or above 27 with weight-related comorbidities. Contraindications, such as a history of certain thyroid cancers or pancreatitis, are carefully assessed to ensure your safety. The doctor's decision is always based on your individual health profile.

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

Many weight loss medications, especially GLP-1 receptor agonists, work by mimicking natural hormones that regulate appetite, slow stomach emptying, and improve blood sugar control. This helps you feel fuller for longer, reducing overall calorie intake. You can expect gradual, sustainable weight loss over several months, not overnight results. These medications are most effective when combined with lifestyle changes, including diet and exercise, and are not a magic bullet for instant weight loss.

Side effects and when to stop

Common side effects of weight loss medications often include nausea, vomiting, diarrhea, or constipation, especially when starting treatment or increasing the dose. These usually subside over time. However, it's important to be aware of red flags such as severe abdominal pain (which could indicate pancreatitis), persistent vomiting, or symptoms of low blood sugar (hypoglycemia) like dizziness and confusion. If you experience any severe or persistent side effects, contact a medical professional immediately. Your doctor will advise you on when to stop or adjust your medication.
