It's also worth knowing that items sold under the same (or very similar) marketing name can have different formulations in different countries. I don't know if that is true for Beecham's Powders, but it is certainly true for some cough medicine formulations*. If you are not aware of this, it can catch you out.
And to emphasize what others have pointed out: being able to buy a medicine/remedy/drug Over-The-Counter (OTC) in the UK does not mean it is legal to possess in all countries outside the UK, and
vice-versa.
*An example is (Canada) BENYLIN Regular Strength Cough and Chest congestion Syrup contains Dextromethorphan; (UK) BENYLIN Chesty Cough Original does not.
