List one or two adverse reactions for the selected agent that would cause you to change therapy.

When selecting a particular treatment for any patient, it is essential to take into account potential side effects that could possibly arise from using the chosen agent. For instance, if a physician prescribes antibiotics then they must also be aware of any adverse reactions – such as nausea or headaches – which could occur during this course of therapy and would require them to switch medications if these symptoms persist.

Moreover, certain drugs can cause more serious side effects ranging from increased risk of bleeding or organ damage in some cases which should also be weighed before making a final decision. Additionally, drug interactions with other treatments being taken by the same individual must also be factored into the equation when evaluating alternatives as these too can potentially lead to unwanted outcomes.

Ultimately, by understanding various risks associated with each agent – physicians can better tailor therapies towards meeting their patient’s specific needs while minimizing any potential harm that may result.
