Who qualifies
You qualify for an online consultation with Hi-Doctor if you are an adult patient located in the EU. Our doctors review every case individually to ensure treatment appropriateness. The specific criteria for weight-loss medications depend on your individual health profile, medical history, and BMI, as per current EU guidelines for approved treatments like Wegovy, Mounjaro, Ozempic (off-label), and Saxenda.
What the medication actually does
Ketoconazole, primarily an antifungal medication, is currently being investigated for its potential role in weight management by modulating hormone levels. However, it is experimental and not approved for this use in the EU. Instead, EU-approved weight-loss medications work through various mechanisms:
- GLP-1 Receptor Agonists (e.g., Semaglutide in Ozempic/Wegovy, Liraglutide in Saxenda): These mimic a natural hormone, helping to regulate appetite, reduce food intake, and promote a feeling of fullness. They also slow gastric emptying.
- Dual GIP and GLP-1 Receptor Agonists (e.g., Tirzepatide in Mounjaro): This newer class offers enhanced effects on appetite regulation and glucose metabolism, leading to significant weight reduction.
These medications are prescribed for adults with obesity or overweight with at least one weight-related comorbidity, when diet and exercise alone have been insufficient.
Side effects and when to stop
Since Ketoconazole is not an approved weight-loss medication, its specific side effects for this use are still under investigation. For approved weight-loss medications, common side effects can include nausea, vomiting, diarrhoea, constipation, and abdominal pain. These often subside as your body adjusts to the medication.
You should stop treatment and consult a doctor immediately if you experience:
- Severe abdominal pain, which could indicate pancreatitis.
- Persistent vomiting or diarrhoea leading to dehydration.
- Any severe allergic reaction (rash, swelling, difficulty breathing).
Your Hi-Doctor physician will provide detailed information on potential side effects and when to seek medical attention if a prescription is issued.
