"PO q12" on a prescription indicates that the medication should be taken "by mouth" (PO stands for "per os," Latin for "by mouth") every 12 hours (q12). This dosing schedule means the patient should take the medication twice a day, spaced roughly 12 hours apart. It's important for the patient to adhere to this timing to maintain consistent therapeutic levels of the medication in their system.
