Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Lantus 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

Whether Lantus contains gelatin depends on the formulation — capsule shells often do, tablet coatings sometimes do. The patient leaflet for Insulin Glargine at 100 IU/mL lists excipients; the manufacturer or pharmacist can confirm gelatin source if not explicitly stated.

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 Lantus product.
