One pharmacy visit tells you little about the next country
A traveller's story of getting a medicine in one country says nothing about the current rule in another. Ask the national regulator or a licensed local pharmacist about the exact product, whether you need a prescription and how the pharmacy will supply it. Find out whether the product is authorised locally, specially imported or only advertised. An advert is no evidence of lawful supply.
Brazil and Mexico show why current rules matter
Brazil now requires pharmacies to keep prescriptions for GLP-1 medicines. The rule applies in Brazil alone, but it shows how fast old travel stories go out of date. Mexico has published counterfeit medicine alerts, so check the supplier and the pack in your hand. Neither example means the whole class of medicines is banned across the region.
A single trip can cross several customs systems
A cruise, an island-hopping holiday or an overland trip may take you through several sets of entry rules. List every stop and check the allowed quantity and paperwork for each one. Permission from your departure country or the cruise line's boarding policy does not cover the rest. Keep a prescription record and labelled packaging. Ask the pharmacist how to handle your product during transfers and spells without reliable storage.
Confirm local approval where the status is open
Where no detailed product record exists for a country, confirm the local status yourself. Check Mounjaro, Wegovy injection, Wegovy tablets and Foundayo one by one. An open status does not mean they are illegal. Set up a plan led by a clinician and compare the full ongoing cost before you buy. The regional list points you to the next question and the right authority. No regional permission to buy a prescription medicine exists.

Your own medicine leaflet and prescriber come first. A source from another country does not mean the same rule applies in the UK.
