Hepatotoxic adverse drug reactions are associated with significant morbidity and mortality and are the leading cause of postmarketing regulatory action in the United States.

This type of adverse drug reaction is usually predictable but sometimes unavoidable. It may occur if a drug dose is too high (overdose reaction), if the person is unusually sensitive to the drug, or if another drug slows the metabolism of the first drug and thus increases its level in the blood (see Drug Interactions). Dose-related reactions may or may not be serious, but they are relatively common.
Idiosyncratic adverse drug reactions result from mechanisms that are not currently understood. This type of adverse drug reaction is largely unpredictable. Examples of such adverse drug reactions include rashes, jaundice, anemia, a decrease in the white blood cell count, kidney damage, and nerve injury that may impair vision or hearing.

Adverse drug reactions (ADRs) are increasingly common and are a significant cause of morbidity and mortality. Historically, ADRs have been classified as type A or type B. Type A reactions are predictable from the known pharmacology of a drug and are associated with high morbidity and low mortality…
Type A reactions are consistent with an increase in a drug’s pharmacological actions. Therefore, these are also called pharmacological adverse reactions. They are dose-dependent and thus easily reversible when reducing the dose or withdrawing the medication.
An adverse drug reaction is a harmful reaction to a medicine given at the correct dose. The reaction can start soon after you take the medicine, or up to 2 weeks after you stop. An adverse drug reaction can cause serious conditions such toxic epidermal necrolysis (TEN) and anaphylaxis.
