Traveling to Korea with sleep medication
The line is sharp: every prescription hypnotic needs written MFDS approval before entry, while over-the-counter antihistamine sleep aids travel freely. Which side your medication falls on:
Medication by medication
Ambien / Stilnox (zolpidem)
MFDS permit requiredAnnex 6 psychotropic, in any quantity. The upside: zolpidem has long been Korea's most prescribed hypnotic, so continuing with a Korean doctor is easy.
Lunesta (eszopiclone)
MFDS permit requiredNot named in the annex, but covered as the isomer of zopiclone. Sold in Korea under local brands, so refills are possible.
Imovane / Zimovane (zopiclone)
MFDS permit requiredAnnex 6. Racemic zopiclone is no longer marketed in Korea; a Korean doctor would switch you to eszopiclone or zolpidem.
Restoril (temazepam)
MFDS permit requiredAnnex 6, and no finished product is sold in Korea, so bring your whole supply.
Halcion (triazolam)
MFDS permit requiredAnnex 6, sold in Korea under the same brand name.
Trazodone (Desyrel)
No permit neededNot controlled in Korea, and commonly prescribed there for insomnia as Trittico.
Unisom SleepTabs (doxylamine)
No permit neededUncontrolled, and sold over the counter at Korean pharmacies as a sleep aid.
ZzzQuil / Benadryl (diphenhydramine)
No permit neededUncontrolled, and sold over the counter in Korea as 50 mg sleep capsules.
Questions
Why do a few sleeping pills need a permit when antihistamine sleep aids do not?
Korea's rule follows its controlled-substance schedules. Zolpidem, the z-drugs, and benzodiazepine hypnotics sit in annex 6 of the narcotics decree; antihistamines like doxylamine and diphenhydramine do not appear in any annex. The permit requirement tracks that list exactly.
What about melatonin?
Unsettled, and we do not publish a verdict without an official source. Melatonin is prescription-only within Korea and foreign melatonin supplements are blocked from e-commerce import, but no published rule addresses hand-carried personal supplies. Ask the MFDS (narcotics@korea.kr) before packing it, and keep it in original packaging if you do.
I just want something for jet lag on the flight. What is the simplest legal option?
An OTC antihistamine sleep aid such as doxylamine or diphenhydramine: no permit, no declaration within the personal-use allowance, and both are sold in Korean pharmacies if you run out. A few tablets of Ambien, by contrast, still legally require the full MFDS permit.
Can I get a sleeping pill prescribed once I am in Korea?
Yes. Zolpidem, eszopiclone, triazolam, and trazodone are all prescribed in Korea. Korean pharmacies cannot fill foreign prescriptions, so it takes a local consultation; bring a doctor's letter or your records.
