Search for weight-loss medication without a prescription in Slovakia or Czechia and you mostly find ads promising home delivery with no doctor, and websites dressed up as pharmacies. This article sells nothing. It explains what the law says, what regulators warn about, and the safe route.
What the law says
In Slovakia, the Act on Medicines (No. 362/2011, section 22) allows only registered non-prescription medicines to be sold online, only by a licensed pharmacy through its own website, and from abroad only from EU member states. The regulator, ŠÚKL, puts it plainly: prescription-only medicines are available only in physical pharmacies and cannot legally be ordered online.
In Czechia, the Act on Pharmaceuticals (No. 378/2007, sections 84 to 87) limits distance selling to registered non-prescription medicines, sold by a pharmacy operator. The regulator, SÚKL, states that prescription medicines may be dispensed only by pharmacists in pharmacies, and never online or at markets.
So the rule is simple. If someone offers you a prescription medicine without a prescription, through a classified ad, social media or an online shop, the offer is outside the legal supply chain, however professional the site looks.
What might be in the pack
Nobody vouches for the origin, contents or storage of a medicine bought outside a pharmacy. In September 2025 the European Medicines Agency (EMA) warned of a sharp rise in illegal products marketed as medicines for diabetes and weight loss. They may not contain the claimed active substance at all and may contain harmful levels of other substances, putting users at a very high risk of treatment failure or unexpected, serious health problems.
In June 2024 the World Health Organization (WHO) issued a warning on falsified medicines used for diabetes treatment and weight loss. Falsified products were found in Brazil, the United Kingdom and the United States. The WHO noted that they may contain a different, undeclared active ingredient, and that reports of falsified products in this group have risen in all regions since 2022. Anyone buying a prescription medicine outside a pharmacy cannot know what they are taking.
Slovakia's ŠÚKL warns more generally that falsified medicines can contain rat poison, cement, heavy metals, antifreeze or wall paint. Czechia's SÚKL adds that medicines sold outside pharmacies may be expired or stored in the wrong conditions.
Classified ads, social media, online shops and abroad
- Classified ads. Only a licensed pharmacy may sell medicines online, and only non-prescription ones. Czech SÚKL acts against illegal offers in online classifieds, and the EU pharmacy logo may not appear on classified-ad portals or marketplaces at all.
- Social media. Authorities have found hundreds of fake Facebook profiles, ads and e-commerce listings, says the EMA. After INTERPOL's Operation Pangea XVII, involving more than 90 countries including Slovakia, ŠÚKL warned of a rise in falsified medicines promoted on social media for weight loss.
- Sites that look like pharmacies. Fraudulent sites misuse official logos and false endorsements, says the EMA. Regulators do not endorse specific products or brands, so any claim that one does is false.
- Abroad. Many listings are hosted outside the EU, according to the EMA. Czech SÚKL says illegal online pharmacies often ship from outside the EU against payment up front; customs hold the parcels and the buyer loses the money.
Be careful if
- A prescription medicine is offered without a prescription.
- The product is advertised as recommended by a medicines agency or carries an official logo.
- The seller promises miraculous effects or claims it works better than registered medicines.
- You cannot find the manufacturer or the operator, only an order form and a phone number.
- The site has no EU pharmacy logo and is not on the national regulator's list.

How to recognise a legitimate online pharmacy
The EU introduced a common logo for legally operating online pharmacies. It shows the flag of the country where the seller is registered and links to the national regulator's list of every legal online seller. In Slovakia and Czechia it must appear on the pharmacy's pages.
Find the logo
The common EU logo, with the flag of the country where the pharmacy is registered.
Click it
It should take you to the pharmacy's entry on the regulator's site: sukl.sk in Slovakia, sukl.gov.cz in Czechia.
Check for yourself
Open the regulator's list directly rather than trusting the link. Fraudulent sites can copy the logo.
Remember the limit
Even a pharmacy with the logo cannot sell you a prescription medicine online. It may sell only non-prescription medicines.
The last step matters most. If a site with the logo offers a prescription medicine without a prescription, something is wrong.
If you already have a suspicious product
The WHO advises stopping use of any suspicious medicine and reporting it; the EMA asks people to report suspicious websites, ads and products to their national authority: ŠÚKL in Slovakia, SÚKL in Czechia. If you have taken something and feel unwell, see a doctor and say what you took and where it came from. In an emergency, call 155 or 112.
The legal route: a doctor, a prescription, a pharmacy
A doctor assesses your health and decides whether any treatment is appropriate for you. If it is, they issue an e-prescription, which in Slovakia can be collected at any pharmacy in the country, and in Czechia is dispensed at a pharmacy, where an ID card is enough for the pharmacist to find it. If it is not, that answer protects you too.
| Offer without a prescription | Doctor and pharmacy | |
|---|---|---|
| Who checks whether treatment suits you | Nobody | A doctor |
| Origin | Unverified | The legal chain, all the way to the pharmacy |
| What is in the pack | The active substance may be missing or different | A registered medicine |
| If something goes wrong | Nobody to turn to | Your doctor and pharmacist |
- Can I legally buy weight-loss medication without a prescription in Slovakia or Czechia?
- Not if it is a prescription-only medicine. Without a prescription you can legally buy only non-prescription medicines, and online only from a licensed pharmacy. Prescription medicines are dispensed by a pharmacy against a prescription.
- Is it safe to buy from a classified ad or social media?
- No. Nobody vouches for what is in it or how it was stored. The EMA warns that illegal products may lack the claimed substance and contain harmful levels of others.
- Can I order a prescription medicine from a pharmacy abroad?
- Not legally. Both countries allow online supply only of non-prescription medicines, and Slovakia only from EU member states. Czech SÚKL also warns that parcels from illegal sellers outside the EU are held at customs.
- How do I check that an online pharmacy is legitimate?
- Find the common EU logo with a national flag, click it, and check it leads to the pharmacy's entry on the regulator's site, or open the regulator's list directly.
- What if I already have a suspicious product at home?
- Do not use it, and report it to ŠÚKL in Slovakia or SÚKL in Czechia. If you have already taken it and feel unwell, see a doctor and tell them what you took. In an emergency, call 155 or 112.
- Will a doctor prescribe a medicine if I ask for one?
- Not automatically. The doctor assesses your health and decides whether any treatment is appropriate. If it is not, they prescribe nothing, and that is a legitimate outcome.
a.clinic is a technology platform. Healthcare is provided by a licensed doctor, who decides whether any treatment is appropriate for you. We do not decide about specific medicines and do not write about them.
