Why have you been prescribed
Fiasp® and what
is it?
Having diabetes means that managing your blood sugar levels is very important.
You and your healthcare professional have decided that Fiasp®, also known as fast-acting insulin aspart, is the appropriate kind of insulin to help you do this.
In people without diabetes, the body naturally releases enough insulin into the bloodstream. This helps control blood sugar levels and keeps them consistent throughout the day. In people with diabetes, Fiasp® helps the body stabilise blood sugar levels by working in a similar way.
Fiasp® is a mealtime (fast-acting) insulin, also known as a “bolus” insulin, which helps the body regulate blood sugar levels. It works for a shorter length of time than other insulins, such as intermediate-acting or long-acting ones and is normally used in combination with these insulin preparations.
Fiasp® should be injected up to 2 minutes before the start of a meal, with an option to inject up to 20 minutes after starting a meal. This medicine has its maximum effect between 1 and 3 hours after the injection and the effect lasts for 3 to 5 hours. Due to this short action Fiasp® should normally be taken in combination with intermediate-acting or long-acting insulin medicines.
