What are Fiasp Vials?

Fiasp vials contain a fast-acting insulin formulation designed to help control high blood sugar levels in adults and children with diabetes mellitus.

Fiasp contains insulin aspart, a man-made insulin that quickly lowers blood sugar after meals. The vial is a 10 mL multi-dose container, allowing multiple uses with a syringe for precise dosing.

Fiasp acts faster than regular insulin because it includes niacinamide (a form of vitamin B3), which helps it absorb more quickly into the bloodstream.

How Do Fiasp Vials Work?

Fiasp vials lower blood sugar levels through its active ingredient, aspart, which is considered a fast-acting insulin.

When you inject Fiasp, it binds to insulin receptors in your body. This insulin helps muscle and fat cells absorb glucose from the bloodstream and reduces the liver’s release of stored glucose.

Fiasp may also slow down fat and protein breakdown while promoting protein creation.

Its formula, including niacinamide, allows it to act faster than regular insulin, making it ideal for managing blood sugar spikes after meals.

Dosage Information and Usage

Fiasp vials are available in a 10 mL multi-dose vial containing 100 units per mL. This vial is designed for multiple uses and administered with a syringe for subcutaneous injection.

Use Fiasp at the start of a meal or within 20 minutes after beginning to eat. Constantly monitor your blood sugar levels and follow a dosing schedule personalized to your needs.

Dosage Form and Strengths of Fiasp Vials

Fiasp vials contain insulin aspart at a strength of 100 units/mL (U-100).

The 10 mL multi-dose vial is suitable for repeated use with syringes, offering flexibility for individuals who prefer this insulin delivery method.

How to Use Fiasp Vials?

To use Fiasp vials, inject them under the skin (subcutaneous injection) in your stomach, upper leg, or upper arm.

Administer the injection at the meal’s start or within 20 minutes after eating. Rotate your injection sites within the chosen area to avoid skin problems like lumps or thickening.

Never inject into damaged, bruised, or irritated skin. Always use Fiasp precisely as your healthcare provider prescribes, and check your blood sugar regularly to ensure it is within target levels.

Side Effects

Fiasp vials can cause side effects that vary from mild to severe.

Common side effects of Fiasp include skin reactions and weight changes. Severe side effects may include low blood sugar (hypoglycemia), severe allergic reactions, or heart issues.

Frequently Asked Questions

The Fiasp vials contain rapid-acting insulin, which helps control blood sugar after meals.
After first use, the Fiasp vials are good for up to 4 weeks (28 days).
The Fiasp vials contain 10 milliliters of insulin, equivalent to 1,000 units of insulin.
To use the Fiasp vials, wash your hands thoroughly and clean the rubber stopper with an alcohol swab. Next, draw air into the syringe equal to your required dose and insert the needle into the vial, pushing the air in. Then, turn the vial upside down and draw the necessary amount of insulin into the syringe. Remove any air bubbles by tapping the syringe and pushing the plunger slightly. Once you have the correct dose, inject the insulin under your skin as directed by your doctor.
You need to discard Fiasp after four weeks.
Store unopened Fiasp in a refrigerator between 36°F and 46°F (2°C to 8°C) until it expires. If you keep it outside of refrigeration, ensure the temperature does not exceed 86°F (30°C); in this case, you can store it for a maximum of four weeks.
The recommended dosage of Fiasp vials varies per individual, considering factors like body weight, diabetes type, and health condition. For type 1 diabetes, the total daily insulin dose usually ranges from 0.4 to 1 unit per kilogram of body weight, split between rapid-acting insulin (like Fiasp) at meals and long-acting insulin for steady blood sugar control. For type 2 diabetes, the daily dose is between 0.3 and 0.5 units per kilogram, also divided between rapid-acting and long-acting insulin. The doctor determines dosage adjustments, correction doses, and specific recommendations for children based on individual needs.
If you miss a dose of Fiasp, check your blood sugar first. If it is high, take a dose to bring it down. If it is normal, continue with your next scheduled dose.
Fiasp can cause weight gain because it helps remove sugar from your blood, which your body uses for energy.
Fiasp insulin starts working quickly, reaching peak effectiveness 1 to 3 hours after injection. Its effects typically last for 3 to 5 hours.
