Fiasp Insulin

Fiasp is the latest insulin from Novo Nordisk introduced in Australia. It’s a faster acting insulin, designed to help minimise the blood sugar spike after a meal, and help reduce blood sugars faster than rapid acting insulin such as Humalog, Novorapid and Apidra.


Release Rate of Fiasp Insulin

Fiasp is a variation of aspart insulin (rapid acting). They’ve added Vitamin B3 to it to make your body absorb it twice as fast as Novorapid (it enters your blood in 2.5 minutes instead of 5 minutes).

Fiasp peaks between 1 and 3 hours and continues working for 3-5 hours, which is similar to other rapid acting insulins.

Novo Nordisk says Fiasp can be given 2 minutes before a meal and up to 20 minutes after starting a meal, without “compromising overall glycaemic control“ (affecting your blood sugars). In comparison, they advise Novorapid should be taken 5-10 minutes before the start of a meal or shortly after start the meal, if needed.

Like any other medication, speak to your health team to discuss whether this insulin is a good choice for you.
