Multifunctional serotonin agonist/antagonist (HSDD)
Is Flibanserin vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Flibanserin in Flibanserin is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 100mg.
Animal-derived excipients in Flibanserin
Common animal-derived excipients in pharmaceuticals include gelatin (in capsule shells, derived from porcine or bovine sources), lactose (dairy-derived), and certain magnesium stearate sources. The prescribing information and patient leaflet for Flibanserin list excipients; whether they are animal-derived is sometimes specified, sometimes left ambiguous. Flibanserin acts as a serotonin 5-HT1A receptor agonist and 5-HT2A receptor antagonist, with additional effects on dopamine and norepinephrine signalling.
Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Flibanserin excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Flibanserin with vegetable-derived excipients is sometimes possible at 100mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.
Frequently asked questions
Does Flibanserin contain gelatin? ▾
Whether Flibanserin contains gelatin depends on the formulation — capsule shells often do, tablet coatings sometimes do. The patient leaflet for Flibanserin at 100mg lists excipients; the manufacturer or pharmacist can confirm gelatin source if not explicitly stated.
Is Flibanserin suitable for vegans? ▾
Most modern tablet formulations are vegan-compatible (active ingredient synthetic, excipients usually plant or mineral), but capsule shells and some coatings may use animal-derived components. For strict vegan requirements, confirm with the manufacturer or pharmacist for the specific Flibanserin product.
