When a patient experiences an allergic reaction to contrast material, the most appropriate action is to follow emergency protocols and notify medical personnel. This response is critical as allergic reactions can range from mild to severe, including anaphylaxis, which requires immediate medical intervention. Promptly alerting medical personnel ensures that the patient receives the necessary treatment, such as administering epinephrine, stabilizing the airway, or providing other appropriate interventions based on the severity of the reaction.

While instructing the patient to remain calm is important, it does not address the immediate need for medical attention. Similarly, waiting for the reaction to resolve on its own could put the patient at risk, as allergic reactions can escalate quickly. Administering over-the-counter antihistamines might be suitable for mild allergic reactions, but it is not adequate for managing potentially severe reactions and does not substitute for professional medical care. Therefore, following established emergency protocols and engaging medical personnel is essential for patient safety in this scenario.
