What is the correct interpretation of the prescription label indicating "1 tsp qid pc prn allergy"?

The prescription label indicating "1 tsp qid pc prn allergy" provides specific instructions for medication use. Breaking down the components of this label offers clarity:

• "1 tsp" indicates the dosage to take, which is one teaspoon.

• "qid" stands for "quater in die," a Latin term meaning four times a day.

• "pc" translates to "post cibum," meaning after meals.

• "prn" means "pro re nata," indicating that the medication should be taken as needed.

Thus, combining these interpretations, the prescription directs the patient to take one teaspoon of the medication four times daily, specifically after meals, and only when necessary for allergy symptoms. This makes option A the correct interpretation of the prescription label.

In contrast, the other choices misinterpret aspects such as the frequency (twice daily instead of four times), meal timing (before meals or regardless of meals), and the usage of "prn" (as needed versus fixed schedule). Overall, understanding medical abbreviations and their meanings is crucial for accurately interpreting medication instructions.
