qPM stands for Every evening, a prescription abbreviation.

Usage notes

Also written q.p.m., QPM or qpm. Not formally banned, but ISMP warns about a related form, "q6PM" (every evening at 6 PM), which has been misread as "every 6 hours". Writing "daily at 6 PM" or "every evening" avoids the problem.
