depends where you live.
In canada and I'm sure the UK you just walk into the pharmacy and say "HAND OVER THE PERIACTIN BEEOTCH!!!" After they laugh at you, then you ask again in a non handicapped way.
In US i'm not sure... I can't see why you'de need a perscription, just go ask them.
It cost me 26.99 canadian for like 50 tabets I think.
