Caverject vs generic: are they the same?
Caverject is the originator brand for the active ingredient Alprostadil. Once the original patent expired, authorised generic versions of the same active ingredient became available. For most users at 10mcg, 20mcg, 40mcg, the practical question is: is the generic just as good, and what really differs?
What is the same
Authorised generics of Alprostadil contain the same active substance at the same 10mcg, 20mcg, 40mcg strength as Caverject, with regulator-required bioequivalence to the originator. Clinical effect is, on average, the same. According to the prescribing information, generics meet the same regulatory standard and can substitute for the brand in most patients.
What can differ
Differences include manufacturer, country of production, excipients, tablet appearance, packaging and price. A small minority of patients react to a specific excipient that varies between manufacturers. Price is usually significantly lower for generics — often the most decisive practical difference for chronic use.
