For a non-life-threatening illness, minor injury or prescription need outside ordinary business hours, do not assume the nearest clinic or pharmacy is open. Korea's Ministry of Health and Welfare uses the 129 Health and Welfare Call Center to provide guidance, and its current holiday notices include information on emergency medical institutions and pharmacies operating during holiday periods.
Call 129 in Korea for current guidance before making a long trip to a facility. The current 129 service information lists the general counseling hours as weekdays 09:00–18:00, while selected urgent welfare and emergency-support categories operate 24 hours. For travelers calling from overseas, the listed number is +82-31-389-7000.
For holiday pharmacy or clinic information, ask for a facility that is open now in the area where you are staying, then confirm the facility's own status if possible. Holiday rosters and operating hours can change, and a listing does not guarantee that a specific medicine, specialist or foreign-language service is available.
If the situation is severe, rapidly worsening or life-threatening, call 119 rather than waiting for a pharmacy or routine clinic. This page is for practical after-hours access, not emergency triage.
