What does QHS close-fisted on a perscription instuction sticky label?
Answer:
every bedtime
{from Latin, quaque hora somni}
Stupid unless they say-so it in English too, but here you have it.
At bedtime. HS stands for hora somni, which is Latin. Most of the abbreviation you see in a prescription come from Latin. The Q is a segment that many doctors drag along from QD (quaque die = every day).
It's a grammatical error from somebody who didn't revise his Latin. Q's pop up in the darndest places on prescriptions because of the widely held belief that it ability "every." The intent of "QHS" is that the drug should be taken at bedtime. The proper label is simply HS, horum somni.
QHS method once at night. I don't know why they don't purely say that.
