Abstract
Medications are essential components of modern healthcare, used to prevent, treat, and manage diseases across the world. While their benefits in improving life expectancy and quality of life are undeniable, medications may also produce unintended physiological effects, known as side effects. This article explores both the beneficial and adverse effects of pharmaceuticals, explains the biological basis for side effects, and emphasizes the importance of patient education and professional consultation. A balanced, evidence-based understanding of medications enables safe, rational, and effective use, ensuring that therapeutic benefits outweigh potential risks.
