Excessive levels of lithium can be harmful to the kidneys, and increase the risk of side effects in general. As a result, kidney function and blood levels of lithium are monitored in patients being treated with lithium. [2] Therapeutic plasma levels of lithium range from 0.5 to 1.5 mEq/L, with levels of 0.8 or higher being desirable in acute ...
Lithium – Lithium is the "classic" mood stabilizer, the first to be approved by the US FDA, and still popular in treatment. Therapeutic drug monitoring is required to ensure lithium levels remain in the therapeutic range: 0.6 to 0.8 or 0.8–1.2 mEq/L (or millimolar). Signs and symptoms of toxicity include nausea, vomiting, diarrhea, and ...
Lithium may also increase the release of serotonin by neurons in the brain. [103] In vitro studies performed on serotonergic neurons from rat raphe nuclei have shown that when these neurons are treated with lithium, serotonin release is enhanced during a depolarization compared to no lithium treatment and the same depolarization.

Venlafaxine has also been implicated to create withdrawal symptoms regardless of dosage. [15] Venlafaxine has been implicated in causing the most severe withdrawal symptoms after cessation of use, possibly due to its short half-life. [16] To simplify identifying the principal signs and symptoms, the mnemonic FINISH may be used: Flu-like ...
The higher risk and increased severity of withdrawal symptoms relative to other antidepressants may be related to the short half-life of venlafaxine and its active metabolite. [64] After stopping venlafaxine, the levels of both serotonin and norepinephrine decrease, leading to the hypothesis that the withdrawal symptoms could result from an ...
Individuals who have had more withdrawal episodes are at an increased risk of very severe withdrawal symptoms, up to and including seizures and death. Long-term activation of the GABA receptor by sedative–hypnotic drugs causes chronic GABA receptor downregulation as well as glutamate overactivity, which can lead to drug and neurotransmitter ...
Suddenly stopping a treatment or missing several doses may cause withdrawal-like symptoms. [7] Some studies have shown that antidepressants may increase short-term suicidal thoughts or actions, especially in children, adolescents, and young adults. However, antidepressants are more likely to reduce a person's risk of suicide in the long run. [7]
The diagnosis is generally based on symptoms and supported by a lithium level blood level. [1] [2] Blood levels are most useful six to twelve hours after the last dose. [2] The normal blood serum lithium level in those on treatment is between 0.6-1.2 mEq/L. [1] Some blood tubes contain lithium heparin which may result in falsely elevated ...
