Product Details


Fiasp is a fast-acting mealtime insulin that works quickly to suppress blood sugar levels that rise quickly as a person eats a meal, and it is used for both Type 1 and Type 2 diabetes treatment regimens. It is known as a flexible rapid acting insulin with the way it can be taken immediately preceding the start of a meal to give users more freedom with when they’ll eat. Fiasp works by stemming the production of glucose by the liver and absorbing glucose already present in the blood and converting it to energy. This is a rapid-acting insulin that can be taken during meals or after them, and it starts to work for blood sugar control in as little as 2.5 minutes.
