Acyclovir vs generic: are they the same? — for Italy
Acyclovir is the originator brand for the active ingredient Acyclovir. Once the original patent expired, authorised generic versions of the same active ingredient became available. For most users at 200mg, 400mg, 800mg, the practical question is: is the generic just as good, and what really differs?
Italy context
Authorised generics of Acyclovir are typically dispensed in Italy alongside or instead of branded Acyclovir. Italian farmacie are heavily regulated independent businesses, with a strong pharmacist-as-consultant tradition. Para-farmacie can sell OTC products outside the traditional pharmacy network. The pharmacist applies local equivalence rules at the point of dispensing; the brand vs generic price gap in EUR is usually the most decisive economic factor for ongoing use.
