What does "tid" stand for in terms of frequency of medication intake?

The abbreviation "tid" is derived from the Latin term "ter in die," which translates to "three times a day." In medical practice, this term is used to indicate the frequency with which a medication should be administered to a patient. When a prescription or medication administration instruction states "tid," it instructs caregivers to provide the medication to the patient three separate times throughout the day, allowing for appropriate distribution of the dose over the waking hours. This is important for maintaining effective drug levels in the body and ensuring that the medication has the desired therapeutic effect.
