Right pain in the arse the hayfever last couple of days
Sounds like you've got something else mate, hayfever has nothing to do with your arse. Get down the doctors quick.
I'm a piroten man!
I don't want to ruin your confidence in that brand but the brands are exactly the same, as is Boot's own, Superdrug's own etc etc. Go to a chemist and ask for ceterizine hydrodichloride and you get the same drug for about a fraction of the price. I buy 36 tablets for £3.99 whereas the same tablets marketed as Zirtec, Piroten etc etc are more like £3.99 for 7 tablets.
