Emergency numbers
From the section “Emergency services in Ireland” of the UK government's travel advice for Ireland, written for British travellers. Reproduced without changes to the wording; formatting adapted.
From the section “Laws and cultural differences” of the UK government's travel advice for Ireland, written for British travellers. Reproduced without changes to the wording; formatting adapted.
Illegal drugs
Possession of even small quantities of drugs, including cannabis, carry severe penalties.
You should expect a long jail sentence and heavy fines for possessing, using or smuggling illegal drugs, including when transiting through the airport. Do not offer to carry any items for anyone else when entering or leaving Ireland.
Airports in Ireland have excellent technology and security for detecting illegal items. This is also used to scan the baggage of transiting passengers.
Travelling with medicines
From the section “Medication” of the UK government's travel advice for Ireland, written for British travellers. Reproduced without changes to the wording; formatting adapted.
You can use a UK prescription to get medicines, including special food required for medical reasons, from pharmacies in Ireland. You will have to pay in full for any prescription medicine.
The legal status and regulation of some medicines prescribed or bought in the UK can be different in other countries. If you have questions, contact the Irish Embassy in the UK.

Entry requirements and visas
Visa and entry rules depend on your nationality and change often, so Trip Rulebook does not summarise them. Each government explains the rules for its own citizens. If you travel on another passport, check with the embassy or the official immigration website of Ireland.
This page is guidance, not legal advice. Laws and advice change without notice and are written for each government's own citizens, so they may apply to you differently. Confirm everything with the official source before you travel. Terms of use.
