Yeah, it's pretty weird considering you can get products with codeine in them over the counter...
Yeah, it's really odd - just different laws in different countries.
Some medicines are sold for completely different purposes in the UK compared to the US... for example, the antihistamine, diphenhydramine (in 25mg tablets):
- in the UK is it sold behind the pharmacy counter as the sleeping tablet, Nytol (two-a-night)
- in the US it is sold on the shelf as the anti-allergy tablet, Benadryl (while Benadryl in the UK is non-drowsy and contains acrivastine instead)
