Is Aygestin vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Norethindrone in Aygestin is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 5mg.
Animal-derived excipients in Aygestin
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 Norethindrone list excipients; whether they are animal-derived is sometimes specified, sometimes left ambiguous. Norethindrone binds to progesterone receptors and exerts progestational effects: thickening cervical mucus, suppressing the LH surge, thinning the endometrium and reducing endometrial implant activity…
Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Aygestin excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Norethindrone with vegetable-derived excipients is sometimes possible at 5mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.
Frequently asked questions
Does Aygestin contain gelatin? ▾
Whether Aygestin contains gelatin depends on the formulation — capsule shells often do, tablet coatings sometimes do. The patient leaflet for Norethindrone at 5mg lists excipients; the manufacturer or pharmacist can confirm gelatin source if not explicitly stated.
Is Aygestin 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 Aygestin product.
