Medicines regulator in Switzerland
Are semaglutide and tirzepatide approved in Switzerland?
Switzerland is not part of the EU medicines system. Swissmedic authorises medicines separately, so a product approved in the EU is not automatically approved in Switzerland, and the reverse is also true.
Semaglutide and tirzepatide products are prescription-only medicines in Switzerland. Swissmedic’s published information shows which products are authorised and for which uses.
Who can prescribe weight loss medicines in Switzerland
A doctor has to prescribe these medicines after an assessment. Cantonal authorities license doctors and pharmacies, so a practitioner’s licence can be confirmed with the canton where they work.
Advertising and online offers
Swiss law does not allow prescription medicines to be advertised to the general public. Clinics may describe a weight management service, but not promote a named prescription medicine.
Fake and unlicensed products
The World Health Organization has issued alerts about falsified semaglutide pens found in several regions. Falsified products may contain the wrong ingredient, the wrong amount or something harmful, and can look very similar to the real packaging.
Safer habits: get the medicine from a licensed pharmacy with a prescription, check the packaging and batch details, never buy from a social media seller, and report suspected fakes to Swissmedic.
Botox, fillers and medical aesthetics in Switzerland
Botulinum toxin products are prescription medicines in Switzerland and must be authorised by Swissmedic. Ask who will inject, their qualifications and which product will be used.
What a safe weight loss program looks like
- A real consultation with a named, registered prescriber who reviews your health history and current medicines.
- Clear information on which exact product you would receive, and whether it is a brand-name medicine or a compounded preparation.
- A licensed pharmacy as the supplier, with packaging you can check.
- A follow-up plan for side effects, dose changes and what happens when you stop.
- Nutrition and activity support, not just a prescription.
- Registration you can confirm with the professional council or health authority in Switzerland.

Frequently asked questions
Do I need a prescription for semaglutide or tirzepatide in Switzerland?
Yes. Both are prescription-only medicines in Switzerland, so a registered prescriber has to assess you first.
Is it safe to buy weight loss injections online in Switzerland?
Only from a licensed pharmacy with a valid prescription. Falsified semaglutide pens have been found by regulators, and sellers on social media or websites that skip the prescription are the most common source of them.
What is the difference between semaglutide and tirzepatide?
Semaglutide acts on the GLP-1 hormone receptor. Tirzepatide acts on two receptors, GIP and GLP-1. Both are weekly injections that affect appetite and blood sugar, and a prescriber decides which, if either, is suitable for you.
Can a medical spa in Switzerland offer GLP-1 weight loss?
Some medical spas and aesthetic clinics run weight management programs with a licensed prescriber. Whether that is allowed, and who must be involved, depends on the rules in Switzerland. Ask who prescribes and who follows you up.
Who regulates Botox and fillers in Switzerland?
Swissmedic oversees medicines and medical products in Switzerland. Professional councils decide which practitioners may inject, so check both the product and the practitioner.
