From the Health Products Regulatory Authority website:
"In Ireland, it is against the law to supply prescription medicines by mail order (including through the internet). Manufacturing fake or counterfeit medicines – known as falsified medicines – is also a criminal offence. Illegal prescription medicines that are discovered by customs officials coming into the country are destroyed. There have also been prosecutions and other actions involving website operators."
