Summary

Nasal decongestant naphazoline use was linked to a spontaneous cerebral hemorrhage in a 44-year-old man. This case highlights a potential drug-induced stroke risk, emphasizing careful medication history in patients with unexplained hemorrhages.

Area of Science:

  • Neurology
  • Toxicology

Background:

  • Spontaneous cerebral hemorrhages account for 10% of all strokes.
  • Drug use, including illicit substances, is implicated in 9.5% of strokes among young adults.

Observation:

  • A 44-year-old man with no prior health issues experienced sudden severe headache and high blood pressure.
  • Symptoms began 24 hours after using naphazoline nasal spray.

Findings:

  • Cranial CT scan revealed a hemorrhage in the right thalamus.
  • Cerebral angiography ruled out aneurysms, vascular malformations, and vasculitis.
  • No other stroke risk factors were identified, leading to attribution to naphazoline.

Implications:

  • This case suggests naphazoline may be a potential trigger for spontaneous cerebral hemorrhage.

  • Highlights the importance of considering medication use, even over-the-counter drugs, in the etiology of stroke.
  • Underscores the need for thorough patient history to identify iatrogenic or drug-induced causes of cerebrovascular events.
