What does q.i.d. indicate in dosing?

Explanation:
Dosing frequency abbreviations tell you how often to give a drug in a 24-hour period. q.i.d. means four doses per day, coming from the Latin quater in die. So the idea is to space four administrations roughly every six hours to keep drug levels more even across the day. Practical scheduling might be morning, mid‑day, evening, and night, depending on the medication and patient needs. This differs from once daily, twice daily, or three times daily, which indicate fewer or more frequent dosing within the same 24 hours.
