In medical terms, what is a contraindication?

A contraindication refers to a specific situation or condition in which a particular treatment or procedure should not be used because it may be harmful to the patient. This can arise from various factors such as the patient's medical history, allergies, or potential interactions with other medications. Understanding contraindications is crucial for healthcare professionals, as it ensures patient safety and helps guide decision-making in treatment plans. Recognizing when a treatment is inappropriate prevents adverse effects and promotes better health outcomes for patients.
