Addyi for vegans — animal-origin ingredient questions
For people on a vegan or strict vegetarian diet, the question of whether Addyi (Flibanserin) contains animal-derived ingredients is a real practical concern. Addyi is used for Addyi is indicated for the treatment of acquired, generalised hypoactive sexual desire disorder (HSDD) in premenopausal women.; 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 Addyi and what alternatives may exist around the 100mg dosing strengths.
Capsule shells and tablet coatings in Addyi
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 Addyi prescribing information, the available dosage forms are tablet — 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 Addyi at the 100mg 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 Addyi (Flibanserin) is published with the Women's Sexual Health 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.
Frequently asked questions

The current Addyi prescribing information lists the available forms (tablet); ask your pharmacist about the gelatin status of the specific batch dispensed.
Are there vegan alternatives to Addyi? ▾

For Addyi (Flibanserin) specifically, the availability of a vegan-suitable form depends on the local market. A pharmacist familiar with the Women's Sexual Health class can identify which generic at the 100mg strength uses a plant-based capsule in your country.
