An Rx reading 'iii gtt, AS tid prn pain' should have which set of directions on the dispensing label?

  1. Instill 3 drops in the left eye three times daily as needed for pain

  2. Instill 3 drops in the left ear three times daily as needed for pain

  3. Instill 3 drops in the right ear two times daily as needed for pain

  4. Instill 2 drops in the right eye three times daily as needed for pain

The correct answer is: Instill 3 drops in the left ear three times daily as needed for pain

The correct answer is B - Instill 3 drops in the left ear three times daily as needed for pain. The directions on the label should match the instructions given by the prescriber. In this case, the prescription specifies "AS" which stands for "auris sinistra", meaning left ear. Therefore, option A and D are incorrect as they mention the left eye and right eye respectively. Option C is incorrect as it mentions the right ear instead of the left ear. It is important to follow the exact instructions given by the prescriber to ensure the medication is taken correctly.
