ロペミン小児用細粒0.05%
Loperamide (Imodium)
Loperamide hydrochloride · ロペミン
Loperamide is sold in Japan both on prescription (Lopemin) and over the counter, though Imodium itself is not marketed here and OTC doses are lower. Japanese pharmacies also stock traditional remedies such as Seirogan; for diarrhea with fever or blood, see a doctor rather than self-treating.
