Humulin N

What If I Take an Overdose?

People who take too much of any type of insulin may experience symptoms such as:
  • Low blood sugar levels (hypoglycemia)
  • Fainting
  • Shakiness
  • A fast heartbeat (tachycardia)
  • Confusion
  • Sweating
  • Seizures
  • Coma
  • Loss of life.
If you happen to take too much Humulin N, seek immediate medical attention.
(Click Humulin N Overdose for more information.)


Unopened Humulin N vials and pens should be stored in the refrigerator. It is best to keep the vials refrigerated once they are opened, although they may be kept at room temperature (less than 86 degrees Fahrenheit). Once you start using a pen, you must not keep it in the refrigerator (it must be kept at room temperature). You must discard a Humulin N pen two weeks after you first use it, even if it still contains some insulin.
Keep both forms of this insulin away from direct light or heat. Make sure to keep it out of reach of children.
