The abbreviation "qw" represents which prescribed frequency?

The abbreviation "qw" stands for "once a week." In the context of medication prescribing, this indicates that the medication should be taken or administered one time each week. This frequency helps in managing the dosing schedule for certain medications that may require less frequent administration due to their pharmacokinetics or the conditions they are used to treat.

Other frequencies that are common in prescription writing include "qd" for every day, "qod" for every other day, and "biweekly" for every two weeks, but "qw" specifically designates the weekly interval. Understanding these abbreviations is critical for pharmacy technicians to ensure accurate dispensation and adherence to prescribed therapy.
