What does 'TID' refer to in medication dosages?

'TID' stands for "ter in die," which is Latin for "three times a day." This notation is commonly used in medical prescriptions to indicate the frequency with which a medication should be taken. This helps in establishing a consistent schedule for the patient, ensuring that the medication is administered at regular intervals throughout the day to maintain effective therapeutic levels in the body.

The other options specify different frequencies: once a day, twice a day, and four times a day, which are clearly distinct from the meaning of 'TID.' Understanding these abbreviations is crucial for medication aides to ensure accurate administration and adherence to medication regimens.
