Dosage and Administration:
It is important to follow your veterinarian's prescription instructions for your pet.
Correct Syringe Type
Doses of insulin are measured in units. U-100 insulin contains 100 units/mL 1 mL=1 cc.
With Humulin N, it is important to use a syringe that is marked for U-100 insulin preparations.
Failure to use the proper syringe can lead to a mistake in dosage, causing serious problems for
your pet, such as a blood glucose level that is too low or too high.
To help avoid contamination and possible infection, follow these instructions exactly.
Disposable syringes and needles should be used only once and then discarded by placing the
used needle in a puncture-resistant disposable container.
Properly dispose of the punctureresistant container as directed by your Health Care Professional.
