In medication terms, what does "pg." refer to?

The term "pg." in medication contexts refers to microgram. A microgram is a unit of mass equal to one-millionth of a gram (10^-6 g). This unit is commonly used for measuring very small doses of medications, particularly in cases where precise dosages are critical for patient safety and efficacy. Medications such as hormones, certain vitamins, and some specialized medications are frequently dosed in micrograms to ensure that patients receive an accurate amount that is effective without being excessive. Understanding this measurement is essential for medication aides, as it aids in the proper administration of medications that require precise dosing.
