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 .
Symptoms may recur and treatment for some days may be necessary. Catatonia due to abrupt or overly rapid withdrawal from benzodiazepines, as part of the benzodiazepine withdrawal syndrome, should also respond to lorazepam treatment. [55] As lorazepam can have paradoxical effects, haloperidol is sometimes given at the same time. [54] [56]
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.
Effects of long-term benzodiazepine use may include disinhibition, impaired concentration and memory, depression, [19] [20] as well as sexual dysfunction. [6] [21] The long-term effects of benzodiazepines may differ from the adverse effects seen after acute administration of benzodiazepines. [22]
The rebound effect, or rebound phenomenon, is the emergence or re-emergence of symptoms that were either absent or controlled while taking a medication, but appear when that same medication is discontinued, or reduced in dosage. In the case of re-emergence, the severity of the symptoms is often worse than pretreatment levels.
Supportive care is the mainstay of treatment of benzodiazepine overdose. There is an antidote, flumazenil, but its use is controversial. [2] Deaths from single-drug benzodiazepine overdoses occur infrequently, [3] particularly after the point of hospital admission. [4]
“Mild irritation, redness, and swelling are normal reactions to a laser hair removal treatment,” Dr. Camp says, but he adds that you can minimize the risk of the above side effects by choosing ...
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.
