Questions
Is Benadryl sold in Korea?
The brand is not, but the ingredient is. Korean pharmacies sell diphenhydramine over the counter as sleep aids (Zeromin, Cooldream) rather than as an allergy medicine. For allergies, Korean pharmacies stock cetirizine (Zyrtec) and loratadine (Claritin) without a prescription.
