👉 In medical terminology, an overdose refers to a situation where a person takes more drugs or substances than they are intended to do, leading to a serious and potentially life-threatening condition. This can occur for various reasons such as taking too many doses of a single drug, consuming too much of a substance, or in combination with other medications. An overdosed individual may experience symptoms such as severe nausea, vomiting, chest pain, dizziness, loss of consciousness, seizures, rapid heartbeat, and organ failure.
