Where to buy
Drugstores and pharmacies with a pharmacist on duty. Not sold at convenience stores; online only via licensed pharmacies after a questionnaire.
The same famotidine as Pepcid AC abroad. Japan sells no OTC proton pump inhibitor, so this is among the strongest OTC options for heartburn. Class 1: pharmacist confirmation required. See a doctor if no better after 3 days.
Typical price: ¥1,000 – ¥1,600 (approximate, tax included; varies by store)
