Can I bring Mucinex DM to Korea?
Multi-ingredient product
Required사전 승인 필요
Mucinex DM requires prior approval from the Korean Ministry of Food and Drug Safety (MFDS) before you travel.
Mucinex DM contains dextromethorphan, a psychotropic substance in Korea, so bringing it in requires written MFDS approval. Plain Mucinex without the DM is guaifenesin only and travels freely under the customs personal-use rule.
Ingredient by ingredient
A product follows its strictest ingredient. This is how each active ingredient stands in Korea:
| Ingredient | In Korea | Note |
|---|---|---|
| Guaifenesin600 mg per ER tablet (1200 mg in Maximum Strength) | OK | Not on Korea's controlled lists. Plain Mucinex (guaifenesin only) is fine to bring. |
| Dextromethorphan HBr30 mg per ER tablet (60 mg in Maximum Strength) | Needs MFDS approval | A psychotropic substance in Korea (decree annex 6). Sets the verdict for the whole product. |
Before you fly
- 1.Apply for the MFDS self-treatment permit at least 3 to 4 weeks before departure, online at nedrug.mfds.go.kr or by email to narcotics@korea.kr. Results are issued within 10 business days.
- 2.Prepare a passport copy, your flight itinerary, the prescription, and a doctor's note stating diagnosis and daily dose, in Korean or English. The permit covers up to a 90-day supply.
- 3.Pack the medication in its original packaging with the pharmacy label attached. Loose pills in an unmarked container invite questions you do not want at the border.
- 4.On arrival, take the goods-to-declare channel and show the permit with the medication.
Questions
Can I bring plain Mucinex instead?
Yes. Plain Mucinex is guaifenesin only, which is not controlled in Korea. The problem ingredient is the dextromethorphan in the DM and Fast-Max DM lines.
