The abbreviation qid or q.i.d. is also sometimes written without a period in capital letters as "QID". However it is written, it is one of a number of hallowed abbreviations of Latin terms that have been traditionally used in prescriptions to specify the frequency with which medicines should be taken. Other examples include: <ul> <li>q.d. (qd or QD) is once a day; q.d. stands for "quaque die" (which means, in Latin, once a day).</li> <li>b.i.d. (or bid or BID) is two times a day; b.i.d. stands for "bis in die" (in Latin, 2 times a day).</li> <li>t.i.d. (or tid or TID) is three times a day ; t.i.d. stands for "ter in die" (in Latin, 3 times a day).</li> <li>q_h: If a medicine is to be taken every so-many hours, it is written "q_h"; the "q" standing for "quaque" and the "h" indicating the number of hours. So, for example, "2 caps q4h" means "Take 2 capsules every 4 hours."</li></ul> <a href="http://www.medterms.com/script/main/hp.asp">MedTerms</a> (TM) is the Medical Dictionary of <a href="http://www.medicinenet.com/script/main/hp.asp">MedicineNet.com</a>.
