Official answer


Yes, Admelog is a brand (trade) name for insulin lispro and it is a fast-acting insulin. Admelog:

  • starts working within 0 to 15 minutes of administration
  • can be given 15 minutes before a meal or with a meal
  • peaks in 30 to 90 minutes
  • keeps working for less than five hours (usually two to four hours)
  • should generally be used in regimens with intermediate or long-acting insulin
  • is more convenient and safer than regular insulin.

Admelog is an analog insulin that is made by genetically modifying the structure of human insulin to give it a faster onset of effect and a shorter duration of action.

Admelog can be administered 15 minutes before or with a meal. This has safety benefits over regular insulin that needs to be administered 30 minutes before food, especially if a meal is delayed or forgotten because hypoglycemia (low blood sugar levels) may result.

Admelog also has a shorter duration of effect than regular insulin. This allows it to better mimic how insulin is naturally released in people without diabetes and reduces the risk of side effects such as low blood sugar levels (hypoglycemia) following a meal.
