doustnie

Doustnie is a Polish adverb meaning by mouth or orally. It is used to describe the route of administration for medicines, supplements, and other substances. In medical texts, it indicates that a product should be taken through the mouth rather than by injection, inhalation, or topical application.

In prescriptions and patient information, doustnie is often used alone or in phrases such as “doustnie podawać” or “doustnie przyjmować.” Example: “Doustnie 1 tabletka 2 razy dziennie po posiłkach.” This usage guides patients on how to administer the substance safely and effectively.

Doustnie is part of standard pharmacological and clinical language in Polish. In international contexts, the route is commonly expressed as the Latin term per os (PO) or simply as oral administration, with doustnie serving as the native Polish equivalent.
