I live in the states, but recently, my husband and I took a two week bus tour of the British Isles. There was a cold going around the bus and both my husband and I caught it. In Ireland, we went to the pharmacy and boy what a difference in the UK pharmacies and USA pharmacies.
In the states, they sell everything and anything. toys, food, greeting cards, etc. and you are on your own about what meds to take for a cold. You can ask the pharmacist, but they are usually too busy filling prescriptions.
In the UK, we saw the chemist and she recommended several meds. They worked great. Wish the USA had pharmacies like that.
