Can I bring Hydrochlorothiazide to Korea?
Hydrochlorothiazide · Microzide · Dichlozid
Hydrochlorothiazide can be brought into Korea for personal use. Korean customs treats up to six bottles or a three-month supply as personal use.
Hydrochlorothiazide is not a controlled substance in Korea. It has been sold there since 1960 as Dichlozid and appears in dozens of combination blood pressure pills. Bring it with your prescription; Korean customs treats up to six bottles or a three-month supply as personal use.
At the airport
No permit is needed. Keep the medication in its original packaging, and carry the prescription or a doctor's note if your quantity is near the customs line of six bottles or a three-month supply. Amounts above that line should be declared on arrival.

Questions
My blood pressure pill combines HCTZ with another drug. Still fine?
Yes, as long as the other ingredient is also uncontrolled, which is true of the usual ARB and ACE inhibitor partners. Korea prescribes many of the same combinations, so continuation is routine.
