What is the major consequence of a cumulative effect with regards to medication use?

The major consequence of a cumulative effect in medication use is the increased risk of overdose. A cumulative effect occurs when a medication builds up in the body over time, often because the dosage is too high, the medication is administered too frequently, or the body is unable to eliminate the drug effectively. This can result in a concentration of the drug exceeding therapeutic levels, leading to potentially toxic side effects or overdose, as the system becomes overwhelmed by the substance.

Understanding this concept is crucial for safe medication management, especially in populations such as the elderly or those with liver or kidney impairments, where drug elimination processes may be compromised. Recognizing the signs of a cumulative effect can help prevent serious health consequences and ensure that medications are used safely and effectively.
