Can You Bring Adderall or Sleeping Pills to Korea 2026? Customs Permit Rules and What Happens Without It

Bottom line: If you're packing Adderall, Ambien (zolpidem), Xanax (alprazolam) or Valium (diazepam) for a trip to Korea, a prescription from home is not enough. You need a separate, advance import permit from Korea's Ministry of Food and Drug Safety (MFDS) — regardless of your nationality — or customs can seize and destroy it on the spot.

If you didn't know: the permit is filed online at nedrug.mfds.go.kr, and the legal processing time is 10 business days, so apply at least 10 days before you fly. Travelers who skip this and get stopped at customs lose the medication immediately, no exceptions made for a valid prescription. Even with a permit, the quantity is capped at what you'd need for your trip plus a 5-day buffer, up to a hard ceiling of 90 days' supply. Melatonin trips up a different group: in Korea it's classified as a prescription-only drug, not a supplement, so bringing in the large gummy bottles sold at US pharmacies can get them flagged and blocked as a restricted ingredient rather than a harmless vitamin.

Why: Korean embassies and MFDS notices state that narcotic-classified sleep aids and anti-anxiety drugs — zolpidem, diazepam, alprazolam among them — require advance government approval before entry, no matter where you're from. Since December 27, 2024, that approval can be filed online instead of on paper. Forms must be in Korean or English; anything else needs a notarized translation alongside the original. Products containing cannabis compounds (cannabinol, THC, CBD) don't get approved at all, full stop. Amphetamine-class stimulants like Adderall fall under the same psychotropic-drug framework, though travelers should still confirm the exact paperwork with MFDS's narcotics policy division before departure, since requirements can vary by substance. Plain over-the-counter painkillers aren't covered by this permit system at all — a reasonable personal supply in your luggage is routinely fine — but that's a different situation from ordering large quantities through overseas direct-purchase sites, which run into separate customs clearance blocks.
