T36-T50: Poisoning by drugs, medicaments and biological substances

T45: Poisoning by primarily systemic and haematological agents, not elsewhere classified

Poisoning by primarily systemic and haematological agents, not elsewhere classified, includes various conditions that occur when harmful substances negatively impact the blood or other systems in the body. These substances, which can be introduced into the body through ingested food, medication, or other methods, affect the body's ability to fight off disease, produce blood cells, or perform other important functions. Common symptoms of these conditions include fatigue, fever, unexplained bruises, and abnormal bleeding. Over time, these conditions can lead to a decrease in general health and could affect multiple organ systems. It's important to note that the symptoms and disease progression can vary significantly based on the specific substance involved, the amount, and length of exposure.
