A paradoxical reaction (or paradoxical effect) is an effect of a chemical substance, such as a medical drug, that is opposite to what would usually be expected. An example of a paradoxical reaction is pain caused by a pain relief medication .
Paradoxical behavior is often not recalled by the patient due to the amnesia-producing properties of the drug. In extreme situations, flumazenil can be administered to inhibit or reverse the effects of midazolam. Antipsychotic medications, such as haloperidol, have also been used for this purpose. [47] Midazolam is known to cause respiratory ...
Paradoxical disinhibition is a paradoxical reaction, an uncommon but recognized phenomenon, characterized by acute excitement and an altered mental state, caused by benzodiazepines. The mechanism is poorly known, but the most accepted theory is that it occurs secondary to inhibition of the restraining influences of the cortex and frontal lobe ...
Paradoxical reactions are rare in the general population, with an incidence rate below 1% and similar to placebo. [ 8 ] [ 120 ] However, they occur with greater frequency in recreational abusers, individuals with borderline personality disorder , children, and patients on high-dosage regimes.
Adverse drug reaction (ADR), a harmful unintended result caused by taking medication; Combined drug intoxication; Conservative management; Drug-drug interaction (DDI), an alteration of the action of a drug caused by the administration of other drugs; Paradoxical reaction, an effect of a substance opposite to what would usually be expected
Both substance use and alcohol can cause both long-term and short-term memory loss, resulting in blackouts. The most commonly used group of prescription drugs which can produce amnesia are benzodiazepines, especially if combined with alcohol, however, in limited quantities, triazolam (Halcion) is not associated with amnesia or memory impairment.
Others must be bioactivated into a toxic compound that will in turn bind to proteins. The second criterion of cellular damage can come either from a toxic drug/drug metabolite, or from an injury or infection. These will sensitize the immune system to the drug and cause a response. Idiosyncratic reactions fall conventionally under toxicology.
These effects are paradoxical to the use of benzodiazepines, both clinically and non-medically, in management of mental health conditions. [44] [45] Long-term benzodiazepine use may lead to the creation or exacerbation of physical and mental health conditions, which improve after six or more months of abstinence.
