Serotonin syndrome (SS) is a group of symptoms that may occur with the use of certain serotonergic medications or drugs. [1] The symptoms can range from mild to severe, and are potentially fatal. [4] [5] [2] Symptoms in mild cases include high blood pressure and a fast heart rate; usually without a fever. [2]
Overdose is usually treated symptomatically, especially in the case of serotonin syndrome, which requires treatment with cyproheptadine and temperature control based on the progression of the serotonin toxicity. [87] Patients are often monitored for vitals and airways cleared to ensure that they are receiving adequate levels of oxygen.
Lithium toxicity, also known as lithium overdose, is the condition of having too much lithium. Symptoms may include a tremor, increased reflexes, trouble walking, kidney problems, and an altered level of consciousness. Some symptoms may last for a year after levels return to normal. Complications may include serotonin syndrome. [1]
The intensity of the symptoms of serotonin syndrome vary over a wide spectrum, and the milder forms are seen even at nontoxic levels. [157] It is estimated that 14% of patients experiencing serotonin syndrome overdose on SSRIs; meanwhile the fatality rate is between 2% and 12%. [152] [158] [159]
Serotonin syndrome is typically caused by the use of two or more serotonergic drugs, including SSRIs. [118] Serotonin syndrome is a condition that can range from mild (most common) to deadly. Mild symptoms may consist of increased heart rate , fever , shivering, sweating , dilated pupils , myoclonus (intermittent jerking or twitching), as well ...
Symptoms caused by excessive adrenergic signalling can occur alongside those of serotonergic signalling. One example would be: overdose of drug(s) influencing multiple targets including serotonin, and adrenergic systems, with concurrent MAOI use). Abnormal echocardiograms, or chest pain are indicative of adrenergic crisis. [23]
Although depletion of tryptophan — the rate-limiting factor of serotonin synthesis — does not influence the mood of healthy volunteers and untreated patients with depression, it does produce a rapid relapse of depressive symptoms in about 50% of remitted patients who are being, or have recently been treated with serotonin selective ...
Symptoms may include elevated body temperature, blurred vision, dilated pupils, sleepiness, confusion, seizures, rapid heart rate, and cardiac arrest. [1] If symptoms have not occurred within six hours of exposure they are unlikely to occur. [2] TCA overdose may occur by accident or purposefully in an attempt to cause death. [2]
