The capacity of a drug to do damage or cause adverse effects in the body is called toxicity.
In general terms, toxicity can be described as something that is harmful. In medical terms, toxicity can be described as the ability of any chemical or drug to damage the body of a person.
Drugs, of various kinds, can cause serious adverse effects on a person. Even drugs that are used for medical purposes can cause adverse reactions when not used properly, without the prescription of a doctor. Hence, to avoid toxicity by a drug, a person should only take a drug that is prescribed by a doctor. The toxicity of a drug can even lead to lifelong damage or death of a person.
