SEVERE HYPONATREMIA, EPISTAXIS, AND FLUOXETINE

Area of Science:

• Clinical Medicine
• Pharmacology
• Endocrinology

Background:

• Hyponatremia is a frequent and potentially fatal electrolyte disturbance.
• Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine, are known to rarely cause hyponatremia.
• SSRIs may also be associated with an increased risk of bleeding events.

Observation:

• A 66-year-old woman presented with symptoms of severe hyponatremia.
• The patient was concurrently using fluoxetine for treatment.
• Epistaxis (nosebleeds) was also noted as a concurrent symptom.

Findings:

• The clinical presentation suggests a possible association between fluoxetine use and the development of severe hyponatremia.
• The co-occurrence of epistaxis raises concerns about fluoxetine's potential impact on hemostasis.
• This case underscores the rare but significant risks associated with fluoxetine therapy.

Implications:

• Clinicians should be vigilant for hyponatremia and bleeding risks in patients prescribed fluoxetine.
• Early recognition and management are crucial for patients experiencing these adverse effects.
• Further investigation into the mechanisms underlying fluoxetine-induced hyponatremia and bleeding is warranted.
