About Provigil

Provigil serves as the original brand name for Modafinil, a medicine indicated for excessive sleepiness linked to narcolepsy. Identical formulations appear under names such as Modavigil, with the compound initially developed by Cephalon. Tablets are the standard form of administration, often found in strengths of 100mg and 200mg.

Provigil availability in Asia

Provigil is registered across 14 markets including Malaysia, the Philippines and Indonesia, with availability also in Taiwan, South Korea and Japan. Generic Modafinil, often produced in Indian pharmaceutical facilities, remains far more affordable than the original brand. These options provide consistent access for expats and individuals situated far from a well stocked pharmacy, though this medicine is best used under a doctor’s care.
