What Fiasp Is and How It Works

This medicine contains insulin aspart, a rapid-acting insulin analog designed for mealtime use. It begins working soon after injection to reduce post-meal glucose spikes. Insulin aspart Flextouch supports flexible dosing around food when used with a basal insulin. Use it at the start of a meal or shortly after beginning to eat, as directed by your prescriber.

Who It’s For

This treatment is indicated for adults and children with diabetes mellitus who need rapid-acting insulin at meals. It is commonly used alongside a long-acting basal insulin.

Avoid use if you have a known hypersensitivity to insulin aspart or any component of the product. Do not use during episodes of low blood sugar. People with frequent hypoglycemia or hypoglycemia unawareness need careful supervision.

Learn about conditions where mealtime insulin is standard: Type 1 Diabetes. It is also used in insulin-based therapy for Type 2 Diabetes when prescribed.

Dosage and Usage

Dosing is individualized by your healthcare professional. Inject subcutaneously at the start of a meal or shortly after you begin eating. Typical injection sites include the abdomen, thigh, or upper arm. Rotate sites with each dose to reduce skin changes.

Use a new, sterile pen needle for each injection. Prime the pen per the Instructions for Use before the first dose of a new pen. Insert the needle subcutaneously as instructed, deliver the dose, then keep the needle in place briefly to ensure full dose delivery.

Do not share your pen or needles with anyone. Do not transfer insulin from the pen to a syringe. This pen is not designed for use in an insulin pump. Ask your prescriber about timing for correction doses and how to coordinate this therapy with your basal insulin and meals.

Missed Dose and Timing

If you miss a mealtime dose, check your blood glucose and follow your care plan. If you are still eating, take the mealtime dose as directed by your prescriber. If significant time has passed, follow the instructions you were given for missed doses and correction dosing. Do not double doses to make up for a missed one.

Storage and Travel Basics

Keep unopened pens in the refrigerator as directed by the label. Do not freeze. Keep in-use pens at room temperature as allowed by the product labeling, away from heat and bright light. Always keep the cap on when not in use. Discard pens per the labeled in-use timeframe.

While traveling, carry your pens and supplies with you, not in checked baggage. Bring extra needles and a copy of your prescription or a travel letter if needed. Use temperature-controlled handling when required. Do not expose pens to direct sunlight or car interiors on hot days.

Pen Handling and Sharps Disposal

Read the Instructions for Use that come with the pen before the first injection. Prime a new pen as directed. Confirm the dose in the dose window before injecting. After the injection, follow the recommended hold time to ensure complete delivery.

Do not share Fiasp Flextouch pens. Always remove and safely discard the needle after each use. Place used needles in an approved sharps container. When the pen is empty or expired, follow local rules for medication disposal. For needle guidance, see BD Needles Uses.

Benefits

• Mealtime control: rapid action aligned with eating
• Flexible timing: can be used at meal start or soon after
• Prefilled pen: portable, discreet dosing
• Dose accuracy: incremental dosing with clear dose window
• Compatibility: works with basal insulin regimens

Side Effects and Safety

• Low blood sugar (shakiness, sweating, fast heartbeat)
• Injection site reactions (redness, swelling, itching)
• Weight gain over time
• Skin changes at injection sites (lipodystrophy)
• Rash or itching

Serious risks can include severe hypoglycemia, hypokalemia, and allergic reactions. Fluid retention and heart failure can occur when insulin is used with thiazolidinediones. Insulin can interact with many medicines that affect glucose. Discuss all medicines, supplements, and alcohol use with your prescriber. Seek urgent care for signs of severe allergy or very low blood sugar.

Drug Interactions and Cautions

Medicines that may increase or decrease insulin needs include corticosteroids, oral diabetes agents, GLP-1 receptor agonists, SGLT2 inhibitors, thiazide diuretics, ACE inhibitors, and certain antibiotics. Beta-blockers and other sympatholytics can mask hypoglycemia symptoms. Alcohol can raise or lower glucose unpredictably. Never change your dose on your own; consult your healthcare professional.

Do not use this pen in an insulin pump. Do not mix with other insulins in the pen. Monitor glucose regularly, and keep fast-acting carbohydrates available to treat lows.

What to Expect Over Time

This mealtime insulin begins acting quickly, so you may see immediate effects on post-meal readings. Ongoing results depend on consistent dosing, meal planning, and basal insulin coordination. Expect your care team to review glucose logs and adjust your overall regimen over time. Keeping a simple record of meals, doses, and readings can help your clinician fine-tune your plan.

Compare With Alternatives

Other rapid-acting analogs may suit different schedules, devices, or formulary needs. Examples include Humalog® Kwikpen and Apidra® Solostar Pens. Your prescriber can help decide which rapid-acting insulin aligns with your goals and supplies.

Availability and Substitutions

If this item is unavailable, your prescriber may recommend an alternative rapid-acting analog or a different device format. A pharmacist may contact your clinician for substitution guidance when allowed. Ask about comparable dosing if switching from a Fiasp prefilled insulin pen to another mealtime insulin.

Patient Suitability and Cost-Saving Tips

This treatment may fit people who need rapid mealtime coverage and prefer a prefilled device. It may not suit those with recurrent severe lows or allergy to insulin aspart. For savings, consider multi-month fills when appropriate, coordinate refills to reduce fees, and use reminder tools so you do not run out unexpectedly. Discuss plans for travel or schedule changes with your prescriber to keep dosing consistent.
