Pseudoephedrine accumulation in renal failure.

D A Sica1, T J Comstock

Summary

Over-the-counter pseudoephedrine can cause serious adverse effects in end-stage renal disease (ESRD) patients undergoing hemodialysis. Discontinuing this common medication resolved the patient's neurological symptoms, highlighting potential risks.

Area of Science:

  • Nephrology
  • Clinical Pharmacology
  • Neuroscience

Background:

  • End-stage renal disease (ESRD) patients frequently experience neuropsychiatric complications, often linked to polypharmacy.
  • Metabolic encephalopathy is a common complication in ESRD, exacerbated by multiple medications.
  • Over-the-counter (OTC) drugs are often underestimated for their potential adverse effects in this vulnerable population.

Observation:

  • A 64-year-old patient undergoing hemodialysis presented with neurological impairment.
  • The patient was taking conventional doses of pseudoephedrine as part of their medication regimen.
  • Neurologic integrity was restored after the cessation of pseudoephedrine.

Findings:

  • Conventional doses of pseudoephedrine can lead to intoxication and severe neuropsychiatric symptoms in hemodialysis patients.

  • Pseudoephedrine toxicity is a significant risk factor for metabolic encephalopathy in ESRD.
  • Discontinuation of pseudoephedrine effectively reversed the observed neurological deficits.

    • Implications:

    • Healthcare providers should exercise caution when prescribing or recommending OTC medications, including pseudoephedrine, to ESRD patients.
    • The potential for drug-drug interactions and adverse effects of OTC medications in ESRD patients requires careful consideration.
    • This case underscores the importance of a thorough medication review, including OTCs, for patients with end-stage renal disease to prevent serious complications.
