Abstract
CASE PRESENTATION: A woman in her 70s was found unresponsive and brought to our hospital with respiratory distress, cardiomyopathy and volatile alternation between hypotension and hypertension. She was intubated and admitted to intensive care for supportive treatment of suspected baclofen overdose. She gradually recovered and was discharged 10 days after presentation. Laboratory testing confirmed baclofen overdose. CONCLUSION: This case illustrates the classic features of baclofen toxicity but also includes unusual features including ST elevations on ECG and apical ballooning on echocardiogram. Lack of immediate laboratory testing can be a significant diagnostic challenge, so a high index of suspicion is needed to definitively diagnose baclofen overdose. Furthermore, haemodynamic volatility requires careful and frequent re-evaluation of treatment, so early recognition and anticipation of complications are essential for effective management of this life-threatening condition.
