I couldn't get over this after moving here from the UK where you can pick up a pack for 10p in a supermarket.

Yeah, I lived in the UK before and it's a bit mad.

You can't buy antihistamines either, only in pharmacies and they are quite expensive. I remember you could get them in Tesco or Asda for like £2.

That is interesting. In the UK they're both available pretty much everywhere, and they're some of the cheapest drug prices I've seen anywhere in the world... ~20p for 16 tablets or something.

I would say 16 tablets would be closer to 6, or even 8 euro here.
