Quaque (on prescription):When a medication needs to be taken at specific intervals, it is denoted with "q" for the Latin term meaning "once" followed by "h" for the number of hours. For instance, "2 caps q4h" translates to "Take 2 capsules every 4 hours." These abbreviations, rooted in Latin, have been conventionally used in prescriptions to indicate how often a medicine should be administered. Other common examples include:- q.d. (qd or QD) indicates once daily, derived from the Latin phrase meaning "once a day."- b.i.d. (bid or BID) signifies twice daily, from the Latin meaning "twice a day."- t.i.d. (tid or TID) means three times daily, from the Latin for "three times a day."- q.i.d. (qid or QID) refers to four times daily, from the Latin for "four times a day."
