In prescription abbreviations, the letter Q indicates?

Explanation:
Q in prescription shorthand comes from the Latin word quaque, meaning “every.” It signals that the medication should be taken at regular intervals, with the exact timing shown by additional letters or numbers (for example, every 6 hours or every day). So the base meaning is that the dose is to be taken at a consistent frequency, not tied to a specific time point like bedtime or a particular day of the week. You’ll see this concept reflected in examples such as QHS (every night at bedtime), QD (every day), or QW (every week). That straightforward sense—“every”—is why that option fits best. In practice, many systems discourage single-letter abbreviations to reduce dosing errors, but the fundamental meaning remains: it indicates frequency, i.e., every.
