Self-medication involves using substances or influences to self-administer treatment for physical or psychological ailments without medical supervision. Common forms of self-medication include over-the-counter drugs for minor health issues and dietary supplements. While self-medication can provide independence and immediate relief for minor conditions, doctors prescribing for themselves or loved ones risks fueling addiction. Self-medication is most appropriate for common minor issues like headaches, coughs, or skin infections, but serious or ongoing conditions still warrant medical advice.
