About Sleep Aids medicines in Japan

If you’ve been having trouble sleeping lately, an over-the-counter sleep aid might help. Japanese OTC sleep aids use diphenhydramine as their active ingredient — the same antihistamine found in products like Unisom in the US.

Note: These products are intended for occasional use only and are not suitable for chronic insomnia. If sleep problems persist, consult a doctor.

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.
