Caverject for vegans — animal-origin ingredient questions
For people on a vegan or strict vegetarian diet, the question of whether Caverject (Alprostadil) contains animal-derived ingredients is a real practical concern. Caverject is used for Caverject is approved for erectile dysfunction of vasculogenic, neurogenic, psychogenic or mixed aetiology in adult men.; like most prescription medications it can contain excipients or capsule materials whose origin is not always obvious from the outer packaging. Below is what the available labelling typically tells us about animal-origin components in Caverject and what alternatives may exist around the 10mcg, 20mcg, 40mcg dosing strengths.
Capsule shells and tablet coatings in Caverject
The most common animal-derived component in any oral medication is gelatin, used in the shell of soft and hard capsules and extracted from bovine or porcine tissue. According to the Caverject prescribing information, the available dosage forms are injection — gelatin capsules should be assumed non-vegan unless the manufacturer specifies an HPMC (hypromellose, plant-derived) shell. Tablet film coatings are usually plant-based; enteric coatings on a small subset of products can use shellac, an insect-derived resin. Pharmacy staff can confirm which formulation of Caverject at the 10mcg, 20mcg, 40mcg strengths uses gelatin and which does not.
Common excipients of animal origin
Beyond the capsule, several excipients have potential animal-origin variants. Lactose monohydrate, present in many tablets, is dairy-derived. Magnesium stearate and stearic acid can be sourced from animal or vegetable fat — modern pharmaceutical manufacturing typically uses vegetable, but the prescribing information rarely states the source. Cochineal (E120) is a possible colourant of insect origin. The full excipient list for Caverject (Alprostadil) is published with the Erectile Dysfunction (ED) class label; people following strict diets are encouraged to review it for each new prescription, as generic manufacturers can vary in their formulations and excipient choices.
