What does the abbreviation "tid" signify in medication administration?

The abbreviation "tid" stands for "ter in die," which is a Latin phrase that translates to "three times a day." This term is commonly used in medical prescriptions to indicate how often a medication should be taken throughout the day. When a medication is prescribed to be taken tid, it means that the patient should take it at roughly equal intervals, ideally spaced out over the waking hours of the day. Understanding these abbreviations is crucial for ensuring proper medication administration and patient compliance, as it helps both healthcare providers and patients follow the prescribed treatment regimen accurately.
