In prescriptions, what are the instructions for how to take the medication referred to as?

The instructions for how to take the medication in prescriptions are referred to as "signa," which comes from the Latin phrase meaning "to write." This term outlines specific details such as the dosage, frequency, and method of administration for the medication. It is essentially the guidance given to the patient on how to correctly use the prescribed medication.

For context, "inscription" refers to the part of the prescription that contains the names of the medication, strength, and form. "Proscription" indicates a prohibition or something that is not allowed, which is not relevant in this context. "Description" generally relates to a general overview or information about something, rather than specific instructions for medication use. Thus, "signa" is the appropriate term for the instructions directing the patient on how to take their medication.
