Why is it essential to verify a patient's allergies before dispensing medication?

Verifying a patient's allergies before dispensing medication is crucial primarily to prevent potentially dangerous allergic reactions. Allergies can lead to mild to severe reactions, including anaphylaxis, which can be life-threatening. Knowledge of a patient's allergies allows the pharmacy technician or pharmacist to avoid prescribing or dispensing medications that might trigger such reactions, ensuring the safety and well-being of the patient.

Knowing a patient's allergies helps healthcare professionals make informed decisions about medication therapy, providing safer alternatives when necessary. This practice is a fundamental aspect of patient care that enhances therapeutic outcomes and minimizes the risk of adverse effects related to drug allergies.
