Thank you for the reply. So you carry these medications in your carry-on baggage and keep it aside in a resealable plastic bag or something? Well the cough syrup I'm going to carry is called Bricarex A. Well there's the issue that it's not a spice that has been bought from a store, my mum made it at home and I've packed it in a transparent tupperware sort of a container. Would that be okay? Appreciate your help
