Also known as: fast-acting insulin aspart, insulin aspart injection
What is FIASP insulin?
FIASP insulin is a form of insulin that begins lowering glucose more quickly than other forms of insulin in patients with diabetes. As a result, FIASP insulin is the first mealtime form of insulin that can be taken at the start of a meal or within 20 minutes thereafter.
What happens during the treatment?
Other forms of fast-acting insulins work better when injected 20 minutes before a meal in order to regulate blood glucose during and after the meal. However, FIASP insulin is the first form of mealtime insulin that can be injected right before meal with better effect than rapid acting insulins and comparable effect to rapid acting insulins when injected within 20 min after starting a meal. FIASP insulin can be taken according to the doctor’s instructions using a FlexTouch insulin pen, InPen or a conventional insulin injection.
Is any special preparation needed?
FIASP insulin is best taken right before a meal but can still be effective up to 20 minutes after the meal. Patients should not take FIASP insulin if they are having an episode of hypoglycemia or are hypersensitive to insulin.
What are the risk factors?
Potential risks of FIASP insulin include low blood sugar and hypersensitivity and allergic reactions. As with any insulin medication, make sure to follow the doctor’s instructions carefully before use.

Diabetes (Type 1)
Normally, the pancreas produces a hormone called insulin which enables the sugar in the blood to move into the body’s cells to provide energy. In children with type 1 diabetes, the child’s body no longer produces insulin.
