About Digestive Health medicines in Japan
Digestive issues happen to the best of us. Whether you need something for stomach pain, diarrhea, constipation, heartburn, or hemorrhoids, Japan has a wide selection of OTC options at most drug stores.
If you take an MAOI, warfarin, blood pressure medication, or any other regular medication, are pregnant, nursing, or simply not sure, consult your doctor before taking any over-the-counter medication.
