Severe meprobamate poisoning: successful treatment with haemoperfusion

Charcoal haemoperfusion used to treat a 56-year-old woman who had taken a very large overdose of meprobamate was followed by fully recovery. The plasma clearance of meprobamate was 153 ml/min and this compares favourably with values obtained for haemodialysis. The indications for haemoperfusion are reviewed.
