What is the purpose of assessing a patient’s current medications before starting cancer treatment?

The purpose of assessing a patient's current medications before starting cancer treatment is primarily to identify potential drug interactions. Cancer treatments often involve potent therapies that can significantly interact with other medications the patient may be taking. Understanding these interactions is crucial, as they could lead to reduced efficacy of the cancer treatment or cause adverse effects that might jeopardize the patient's health.

Additionally, the complexity of cancer regimens and the nature of medications prescribed for managing cancer symptoms, co-morbidities, or side effects means that healthcare providers must be aware of all medications a patient is currently using. This comprehensive assessment helps ensure the treatment plan is both safe and effective, optimizing the patient's overall care during a critical time in their treatment journey.

Identifying drug interactions is fundamental to preventing medication-related complications, which can range from mild side effects to life-threatening conditions, thereby allowing the clinician to make necessary adjustments to the treatment plan for each individual patient.
