Before you buy a weight-loss pen from a Facebook seller, please read this.
Last year, UK investigators found counterfeit weight-loss pens — sold online and through social media — containing the wrong medicine at many times the intended dose. Medicines regulators seized millions of doses of illegal medicines in 2025, including thousands of black-market weight-loss pens, and Ireland's regulator, the HPRA, has reported a sharp rise in illegal weight-loss products seized here. The sellers haven't gone away. Some of them are in Facebook groups like the ones you may be scrolling right now.
We're a doctor-led clinic in Ireland, so here is the plain version of what keeps people safe:
1. Weight-loss injections are prescription-only in Ireland. Only a registered pharmacy can legally supply them, and only against a doctor's prescription — anyone else selling them is breaking the law.
2. You can check any doctor on the Irish Medical Council register — it's public and free.
3. A legitimate service asks about your health history before anything else. If nobody asks, walk away.
4. No genuine pharmacy sells through DMs, group chats or beauty salons.
5. If the price looks too good to be true, that is the warning.
If you're unsure about something you've seen for sale, ask below — we'd much rather answer a question here than see someone get hurt.
