Unknown: The toxic dose in man is not known. Due to extensive metabolism, blood levels after a standard dose of Diltiazem can vary over tenfold. There have been 29 reports of Diltiazem overdose in doses ranging from less than 1 g to 18 g. Sixteen of these reports involved multiple drug ingestion. 22 people recovered with doses up to 10 g. If you're considering it, please seek help. This isn't a good idea.
