When a medication is prescribed "q.o.d.", how often should it be taken?

The abbreviation "q.o.d." stands for "quaque altera die," which is Latin for "every other day." This means that if a medication is prescribed to be taken "q.o.d.," the patient should take the medication on one day and then skip the following day, resuming on the next day. This scheduling allows for a break in administration that may be beneficial for certain medications, often to reduce side effects or to allow for monitoring of the medication's effects on the patient.

Understanding this medical terminology is crucial for proper medication administration and patient care, ensuring that patients receive their medications as intended by their healthcare providers.
