Travelling with medications can be a complex process due to varying regulations across countries. It’s essential to understand that while certain medications are legally accessible in the UK, they might be restricted or prohibited in other countries. Failing to comply with these regulations could lead to intense scrutiny from customs officials, possible confiscation of medication, and even imprisonment for carrying an excess amount without the appropriate documentation.
