Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Propecia excipients should ask the pharmacist or manufacturer directly.

For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.
Frequently asked questions
Does Propecia contain gelatin? ▾
Whether Propecia contains gelatin depends on the formulation — capsule shells often do, tablet coatings sometimes do. The patient leaflet for Finasteride at 1mg lists excipients; the manufacturer or pharmacist can confirm gelatin source if not explicitly stated.
Is Propecia 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 Propecia product.
