This classification is part of the broader category of poisoning and adverse effects related to medications, specifically focusing on SNRIs, which are commonly prescribed for conditions such as depression and anxiety.

Clinical Description

Definition of SNRIs

Selective serotonin and norepinephrine reuptake inhibitors are a class of medications that increase the levels of serotonin and norepinephrine in the brain by inhibiting their reuptake into neurons. Commonly prescribed SNRIs include venlafaxine, duloxetine, and desvenlafaxine. These medications are primarily used to treat major depressive disorder, generalized anxiety disorder, and certain chronic pain conditions.

Clinical Presentation of Poisoning

Poisoning by SNRIs can occur due to an overdose, either intentional or accidental. Symptoms of SNRI poisoning may vary based on the specific drug involved, the amount ingested, and the individual's health status. Common clinical manifestations include:

• Neurological Symptoms: Agitation, confusion, seizures, or altered mental status.
• Cardiovascular Effects: Increased heart rate (tachycardia), hypertension, or arrhythmias.
• Gastrointestinal Distress: Nausea, vomiting, or diarrhea.
• Serotonin Syndrome: A potentially life-threatening condition characterized by symptoms such as hyperreflexia, tremors, sweating, and fever, which can occur with excessive serotonin levels.

Diagnosis and Management

The diagnosis of poisoning by SNRIs is typically made based on the patient's history, clinical presentation, and, if available, toxicology screening. Management of SNRI poisoning may involve:

• Supportive Care: Monitoring vital signs and providing symptomatic treatment.
