Abstract:
Though drug fever from methyldopa is well known, to my knowledge fever and hypotension simulating septic shock have never been described in this country as a syndrome resulting from methyldopa therapy. Three such cases are presented here, all proved on rechallenge. They erroneously accounted for almost 6% of all cases of septic shock at St Elizabeth Medical Center in the last ten years.
Insights
Drug fever from methyldopa can mimic septic shock, presenting with fever and hypotension. This rare syndrome, confirmed by rechallenge, was observed in three patients.
Area of Science:
- Pharmacology
- Internal Medicine
- Toxicology
Background:
- Methyldopa is a commonly prescribed antihypertensive medication.
- Drug fever is a known adverse effect of methyldopa.
- Septic shock is a life-threatening condition characterized by circulatory dysfunction.
Observation:
- Three cases of patients presenting with fever and hypotension were observed.
- These symptoms mimicked the clinical presentation of septic shock.
- The patients were undergoing methyldopa therapy.
Findings:
- The observed syndrome of fever and hypotension was directly attributed to methyldopa therapy.
- Rechallenge with methyldopa confirmed the diagnosis in all three cases.
- This methyldopa-induced syndrome accounted for nearly 6% of septic shock cases over a decade.
Implications:
- Clinicians should consider methyldopa-induced fever and hypotension in patients presenting with symptoms of septic shock.
- Accurate diagnosis can prevent unnecessary antibiotic use and identify medication-related adverse events.
- This highlights the importance of a thorough medication history in diagnosing complex clinical presentations.
