You could always just ask for it's generic name i.e codeine
linctus and they should give you codinex or which ever thing is available
If that doesnt work out pulmo bailey is another type of codeine linctus over the counter with 7mg/5ml.
Is it just me or do americans have some weird thing about putting caffeine
in cocodamol, I mean few of the Irish/British formulations even have caffeine in thankfully but over there they all seem to have caffeine in, tylenol 2,3,4 and those are prescription >_<
