Quick FAQ

What is lisdexamfetamine?

• Lisdexamfetamine is a prodrug of dextroamphetamine. It is inactive until ingested, where it is cleaved by red blood cells into the active stimulant. This delayed activation helps reduce the potential for abuse compared with immediate‑release amphetamines.

Why does the capsule contain lactose?

• Lactose is a common filler that helps give the capsule its weight and stability. Those with lactose intolerance can check with their prescriber or pharmacist for a suitable alternative formulation.

Can I take Vyvanse if I'm lactose intolerant?

• Many people tolerate the small amount of lactose in a 20 mg capsule, but if you have severe lactose intolerance or a milk allergy, discuss alternative formulations (e.g., a 5 mg or 10 mg capsule, or a generic version) with your provider.

Are there any potential allergens in the tablet?

• The main potential allergens are lactose, gluten (from the capsule shell), and, rarely, excipients such as talc or silicon dioxide. If you have a known allergy, read the label carefully or ask your pharmacist to verify.

How to Verify

1. Check the Packaging – The label on the blister pack or the bottle’s insert lists all active and inactive ingredients.
2. Ask Your Pharmacist – They can confirm the exact composition of the specific product you have.
3. Manufacturer’s Website – For Vyvanse®, visit AbbVie’s product information page for the most up‑to‑date ingredient list.
