Pseudoephedrine, a common nasal decongestant, may trigger ischemic colitis, particularly in women. Discontinuing the medication led to symptom resolution, suggesting a causal link.

Area of Science:

  • Gastroenterology
  • Pharmacology

Background:

  • Ischemic colitis is a rare condition affecting the colon.
  • A previous case report linked pseudoephedrine to ischemic colitis.

Observation:

  • Four women aged 37-50 presented with abdominal pain and hematochezia.
  • All patients had used pseudoephedrine, with three using it daily for a week and one chronically for six months.
  • Colonoscopies revealed colitis, primarily in the splenic flexure, consistent with ischemic injury.

Findings:

  • All patients improved after discontinuing pseudoephedrine.
  • No relapses occurred during 8-12 months of follow-up after stopping the medication.

Implications:

  • Pseudoephedrine's vasoconstrictive properties may cause ischemic colitis in susceptible individuals.

  • Perimenopausal women might be particularly vulnerable due to hormonal fluctuations.
  • This association warrants consideration in the differential diagnosis of ischemic colitis.
