An adverse effect is an undesired harmful effect resulting from a medication or other intervention, such as surgery. [1] An adverse effect may be termed a " side effect ", when judged to be secondary to a main or therapeutic effect .
Therapeutic effect refers to the response(s) after a treatment of any kind, the results of which are judged to be useful or favorable. [1] [2] [3] This is true whether the result was expected, unexpected, or even an unintended consequence. An adverse effect (including nocebo) is the converse
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
Unlike direct side effects, an adverse event does not necessarily mean the medication directly caused the problem. These events can include any unfavorable symptoms, signs, or medical conditions that appear during medical treatment, regardless of whether they are definitively linked to the specific medication being studied.

Adverse drug reaction is effects arising when drug given even in therapeutic dose either immunologically mediated reaction or pharmacologically mediated adverse response or idiosyncratic reaction due to the peculiarities of individual. Adverse event (AE) is a side effect occurring with a drug. By definition, the causal relationship between the ...
In adverse drug reactions involving overdoses, the toxic effect is simply an extension of the pharmacological effect (Type A adverse drug reactions). On the other hand, clinical symptoms of idiosyncratic drug reactions (Type B adverse drug reactions) are different from the pharmacological effect of the drug.
Knowledge of the most common and severe complications of a disease, procedure, or treatment allows for prevention and preparation for treatment if they should occur. Complications are not to be confused with sequelae , which are residual effects that occur after the acute (initial, most severe) [ 1 ] phase of an illness or injury.
The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection). Pharmacodynamics and pharmacokinetics are the main branches of pharmacology , being itself a topic of biology interested in the study of the interactions of both endogenous and exogenous chemical ...
