This is general information about medicines regulation and patient safety, not medical or legal advice. Only a licensed prescriber who knows your health can decide whether a medicine or treatment suits you. Rules and product availability change, so confirm the current position with the official sources linked on this page. MedSpa Listings does not sell, prescribe or supply medicines.
Medicines regulator in Portugal
INFARMED, National Authority of Medicines and Health Products
Are semaglutide and tirzepatide approved in Portugal?
Brand-name semaglutide for weight management, sold as Wegovy, and tirzepatide, sold as Mounjaro, hold marketing authorisations from the European Commission on the advice of the European Medicines Agency. Those authorisations are valid in every EU member state, including Portugal. Both are prescription-only medicines.
An EU-wide authorisation does not mean a product is on pharmacy shelves in every country at the same time. Supply, pricing and public reimbursement are decided nationally, so INFARMED, National Authority of Medicines and Health Products and local pharmacies are the place to check what is currently available in Portugal.
Who can prescribe weight loss medicines in Portugal
Only professionals with prescribing rights in Portugal can prescribe these medicines. National rules decide who those professionals are and whether online consultations can lead to a prescription.
Within the EU, legitimate online pharmacies display the EU common logo, which links to the national register of authorised online sellers. A website without it, or one that sells a prescription medicine without a prescription, is a warning sign.
Advertising and online offers
EU law bans advertising prescription medicines to the general public, and that ban applies in Portugal. Clinics may describe their services, but adverts that promote a named prescription weight loss medicine are a warning sign.
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 INFARMED, National Authority of Medicines and Health Products.
Botox, fillers and medical aesthetics in Portugal
Botulinum toxin products are prescription-only medicines in Portugal. Dermal fillers sold for cosmetic use come under the EU Medical Device Regulation, which brought products with no medical purpose under the same safety rules as medical devices.
Which professionals may inject is decided by national law and professional bodies in Portugal. Ask for the practitioner’s registration, the product brand and how complications are handled.
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 Portugal.
Frequently asked questions
Do I need a prescription for semaglutide or tirzepatide in Portugal?
Yes. Both are prescription-only medicines in Portugal, so a registered prescriber has to assess you first.
Is it safe to buy weight loss injections online in Portugal?
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 Portugal 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 Portugal. Ask who prescribes and who follows you up.
Who regulates Botox and fillers in Portugal?
INFARMED, National Authority of Medicines and Health Products oversees medicines and medical products in Portugal. Professional councils decide which practitioners may inject, so check both the product and the practitioner.
