 Modafinil is not part of India's Schedule-H or Schedule-H1 or Schedule X drugs as of 2018.Though the Central Drugs Standard Control Organisation warned users of potential side-effects in a 2012 report, and in spite of the letters from the DCGI to pharmacies mandating its sale, Modafinil continues to be sold in India with rather lax regulation.In Sweden, modafinil is classified as a schedule IV substance and possession is therefore illegal without prescription.
