In a medication context, what does "sig." indicate?

In a medication context, "sig." is derived from the Latin term "signa," which translates to "let it be labeled." This term specifically refers to the section of a prescription or medication order that provides instructions on how the medication should be taken or administered. These instructions can include details such as the dosage, frequency, and route of administration, effectively serving as the labeling or instructions for the individual taking the medication.

The other options pertain to different aspects of medication management. For example, prescription refill instructions would detail how and when a patient may obtain additional supplies of the prescribed medication, but would not be indicated by "sig." Similarly, the type of medication form refers to whether the medication is a tablet, liquid, injection, etc., which is separate from the specific usage instructions provided by "sig." Lastly, storage instructions are related to how a medication should be stored, such as whether it needs to be kept refrigerated or protected from light, but again, they do not fall under the purview of what "sig." denotes.
