What does the term "cumulative effect" imply in a medical context?

The term "cumulative effect" in a medical context refers to the reaction that occurs over time as a result of exposure to a substance or treatment. This means that the initial exposure to a drug or toxin may not produce significant effects immediately, but as the exposure continues or increases, the effects can accumulate and lead to a more pronounced response.

This concept is particularly important in pharmacology and toxicology, where repeated doses of a medication or repeated exposure to toxins can result in increased effectiveness or heightened side effects. Over time, the body's ability to metabolize and excrete substances may become overwhelmed, leading to potential adverse effects.

Understanding cumulative effects is essential for healthcare providers in monitoring patient responses to medications over time and in managing potential toxicity, especially in cases where patients are on multiple medications.
