 dosage 
The section on dosage states as follows:

""Disulfiram is supplied in 200 mg, 250 mg, and 500 mg tablets. The usual initial dose is 500 mg for 1 to 2 weeks, followed by a maintenance dose of 250 mg (range 125 mg–500 mg) per day. The total daily dosage should not exceed 500 mg.""

This section has no references, and higher initial dosages are prescribed in some contries. In Finland an initial dose of 800 mg per day for two days, followed by a maintenance dose of 200 mg per day, is usually prescribed. Hence, I'm adding the unreferenced tag."
