Naituku

Naituku, a transliteration of the Japanese word 内服 (ないふく), refers to the act of taking medicine orally, meaning to swallow medication for internal use. This encompasses pills, tablets, capsules, liquids, and any other form of medication intended to be ingested. It is a common term used in medical settings within Japan and by individuals familiar with Japanese medical terminology. The term distinguishes oral medication from other routes of administration, such as injections (注射, chūsha), topical applications (外用, gaiyō), or suppositories (坐薬, zayaku).
