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

T45.1: Poisoning: Antineoplastic and immunosuppressive drugs

Immunosuppressants are drugs that suppress the body’s immune system. The immune system protects the body from pathogens and foreign substances. The immune system can also destroy cells in the body that have pathologically changed. Anti-neoplastic agents slow down or prevent the growth of the body’s cells. They can be used for cancers, among other things. Anti-neoplastic agents can also suppress the body’s immune system.

A drug can cause poisoning if, for example, too much of it is taken. The drug may also be administered or taken by mistake.

The symptoms depend, among other things, on which medication caused the poisoning. For example, the person may experience nausea and vomiting. The function of the kidneys, liver or other organs may be affected. Anti-neoplastic agents can cause hair loss. The person may also be more susceptible to infectious diseases.
