What is the recommended frequency for a medication labeled "qd"?

The recommended frequency for a medication labeled "qd" is every day. In medical terminology, "qd" stands for "quaque die," which is Latin for "once a day." This abbreviation is widely used in prescription writing and indicates that the medication should be administered once during a 24-hour period.

Understanding this terminology is crucial for ensuring proper medication adherence and avoiding potential overdosing or underdosing, which can occur if the prescription is misunderstood. Other frequency indications, such as "tid" for three times a day or "q4h" for every four hours, have different meanings and should not be confused with "qd."
