How often is medication prescribed when noted as "tiw"?

The notation "tiw" stands for "three times a week" in medical terminology. This abbreviation is derived from the Latin phrase "ter in semana," which translates to "three times a week." When a medication is prescribed with this frequency, it indicates that the patient should take the medication on three separate days within a week, not including any specific days. This is a common shorthand used in prescription writing to communicate the dosage schedule clearly and efficiently to both healthcare providers and patients. Understanding such abbreviations is crucial for ensuring accurate medication administration and compliance.
