If a client begins to have an allergic reaction during a service, what should the practitioner do?

Discontinuing the use of the product is the most appropriate action for a practitioner when a client begins to have an allergic reaction during a service. This choice prioritizes the client's health and safety. An allergic reaction can escalate, and continuing to use the product could exacerbate the situation or lead to a more severe reaction. By stopping the service immediately, the practitioner can prevent further exposure to the allergen.

Taking swift action also allows the practitioner to assess the situation further, seek medical help if necessary, and provide appropriate responses, such as calming the client and addressing any immediate needs, like removing the product from the affected area. This response is critical because managing an allergic reaction effectively can minimize discomfort for the client and demonstrate the practitioner's professionalism and adherence to safety protocols.

Other options may involve potential risks. Using an alternative product without addressing the underlying reaction could lead to additional complications, while completing the service quickly may endanger the client’s well-being. Consulting further with the client is important, but it should come after ensuring that no further exposure occurs.
