What is the lethal dosage of Insulin?
Patient: Just started keeping track of my dad s sugar levels. It is exceedingly high. How much insulin is too much in a day? He had 55 units this morning and I gave him another 10 about an hour ago. His sugar before the 10 units was 208, I just took it and it s 299??? Doctor: Hello,Usual insulin dosage is one unit per kg per day for regular insulin. But insulin can cause low sugar coma or death in doses which are excessively high. This high dose depends on person to person. Fatal doses record as 400 to 900 units for a person. Hope I have answered your query. Let me know if I can assist you further.Regards,  Dr. Varinder Joshi
