What is it?

Fiasp contains insulin aspart, a rapid-acting insulin analog. Insulin analogs are man-made versions of the naturally occurring insulin. Fiasp is a type of rapid-acting insulin that is available in the bloodstream earlier than human insulin. Rapid-acting insulins such as Fiasp are commonly used in combination with long-acting insulins.

What is it used for?

Apidra is used to improve glycemic control in adults and children with diabetes.

How does it work?

Insulin aspart differs from human insulin in that the amino acid proline in position B28 is replaced by aspartic acid. As a result of these changes, insulin aspart is availabe in the blood stream more quickly after injection than human insulin.


Unopened vials and pens should be stored in a refrigerator, 36°F-46°F (2°C-8°C). In-use insulin can be kept at room temperature (below 86°F), away from direct heat and light. Insulin should not be stored in the freezer, and it should not be allowed to freeze. Discard if it has been frozen.


Apidra is contraindicated in patients who have had hypersensitivity reactions to insulin aspart or one of the excipients.
