The term 'signa' in a prescription refers to what aspect of the prescription?

The term 'signa' in a prescription, derived from Latin, specifically refers to the directions for use of the medication. This includes how to take the medication, the dosage frequency, and any specific instructions on administration. Proper understanding of the signa is crucial for ensuring that the patient knows how to use the medication safely and effectively, which helps to promote adherence to the prescribed treatment.

When assessing the other terms in a prescription, the patient's information typically includes personal details such as name, age, and contact information, while the drug dosage describes the amount of medication to be taken at each use. The prescription date indicates when the medication was prescribed and is essential for tracking refills and expiration, but none capture the meaning of 'signa' as accurately as the directions for use do. Understanding this terminology is vital for pharmacy practice and patient education.
