25% of Patients Face Drug Side Effects — What Really Causes Them?
💡 Why do some medicines trigger unexpected reactions?
Studies show that nearly 1 in 4 patients experience at least one drug side effect during routine treatment. These reactions are not random — they are usually linked to predictable mechanisms such as drug–drug interactions, altered metabolism, organ function decline, and immune sensitivity. For example, when two medicines share the same liver enzyme pathway, one can build up in the bloodstream and cause nausea, dizziness, or skin rashes. In older adults, slower kidney clearance can lead to higher-than-expected drug levels. Understanding these root causes is the first step in protecting yourself.
