Correct Answer is B
Explanation
Rationale:
A. Dosage strength: The dosage strength indicates the amount of active drug per unit but does not provide information about potential allergens. Allergic reactions are not related to the amount of the active ingredient alone.
B. Inactive ingredients: Inactive ingredients, such as dyes, preservatives, or fillers, can trigger allergic reactions in sensitive patients. Reviewing this information is essential to prevent adverse allergic responses and ensure patient safety.
C. Therapeutic class: The therapeutic class describes the general action or purpose of the drug, such as antihypertensive or antibiotic, but it does not indicate potential allergens present in the formulation.
D. Expiration date: The expiration date ensures the medication is safe and effective to use but does not provide any information regarding allergens or allergy risks associated with the drug.
