adverse effect (medicine)


adverse effect


This is an abnormal or harmful effect to an organism caused by exposure to a chemical. It is indicated by some result such as death, a change in Food or water consumption, altered body and organ weights, altered enzyme levels, or visible illness. An effect may be classed as adverse if it causes functional or anatomical damage, causes irreversible change in the homeostasis of the organism, or increases the susceptibility of the organism to Other chemical or biological stress. A non-adverse effect will usually be reversed when the organism is no longer being exposed to the chemical.
