Where did you find that information?

It is my understanding that the countries you mentioned are the less tolerant. I think they will not allow any meds to enter their countries, if detected, unless a valid perscription is shown and duties are paid. Germany most likely will not allow any meds not coming from the European Union with or without a prescription

The U.K. does allow meds for personal use, many menbers reported having to collect their meds at customs, or the customs area of the post office, and paying the VAT (Tax)...

Small and well organized countries like Finland and Norway have excellent custom services, they will separate any pack if they think the can charge you some taxes, then if it is prescription meds they will ask you for a valid prescription.
