T36-T50: Poisoning by drugs, medicaments and biological substances
Poisoning by drugs, medicaments and biological substances refers to a group of conditions that occur when a person accidentally or purposely ingests or is exposed to harmful amounts of these substances. This can happen through overdose, misuse, or incorrect administration. The transmission occurs primarily through ingestion, inhalation or skin contact. A wide range of symptoms may present, depending on the substance involved and the individual's body response. Common symptoms include altered mental state, such as confusion or drowsiness, seizures, nausea, vomiting, abdominal pain, or abnormal heart rhythms. The progression of these conditions can range from mild symptoms to life-threatening emergencies, impacting various systems of the body including the nervous, digestive and cardiovascular systems. Each condition within this group is distinct, relating to the type and amount of substance involved.
