オメプラール錠10 10mg
Omeprazole (Prilosec)
Omeprazole · オメプラール
Omeprazole is prescribed in Japan as Omeprazole/Omepral 10 and 20 mg, though doctors now more often choose lansoprazole, esomeprazole or vonoprazan. Bring your own Prilosec OTC under the 2-month rule; for heartburn without a doctor, the OTC option here is famotidine (Gaster 10).
