Studies in the 1990s in Australia and the United Kingdom showed that between 8 and 12% of drug overdoses were following TCA ingestion. TCAs may be involved in up to 33% of all fatal poisonings, second only to analgesics. Another study reported 95% of deaths from<unk> s in England and Wales between 1993 and 1997 were associated with<unk><unk> s, particularly dothiepin and amitriptyline. It was determined there were 5.3 deaths per 100,000 prescriptions. Sodium channel blockers such as Dilantin should not be used in the treatment of TCA overdose as the Na+ blockade will increase the QTI.
