What is the first step to take in case of an adverse reaction?

The crucial first step in the case of an adverse reaction is to contact a healthcare professional. This step ensures that the individual receives immediate and appropriate evaluation and care. Adverse reactions can range in severity and complexity, potentially leading to serious health implications if not addressed promptly. A healthcare professional has the expertise to assess the situation, determine the need for interventions, and decide on further actions, such as monitoring or administering treatments to mitigate the adverse effects.

Taking other actions, such as documenting the reaction, waiting for it to subside, or administering more medication, might delay necessary care or potentially worsen the individual's condition. Thus, the priority is always to seek professional guidance to manage the situation safely and effectively.
