Do side effects vary among individuals?

• A. They vary from person to person
• B. They are the same for everyone
• C. They only occur with illegal drugs
• D. They are always dangerous

Answer: (A)

Side effects vary among individuals because our bodies process and respond to drugs differently. Genes can affect how quickly a drug is metabolized, which can change both how strong the effect is and how long it lasts. Factors like age, body weight, overall health, liver and kidney function, and interactions with other medications or foods also play a role. Because of these differences, one person might notice a certain side effect, another might have a different one, and another might barely feel anything at all. This isn’t limited to any particular kind of drug—side effects can occur with prescription medicines, over-the-counter drugs, and even supplements. And most side effects are not always dangerous; many are mild or temporary, such as a slight stomach upset or dizziness, while more serious effects are less common but possible depending on the individual and the medication.
