Fiasp® Flextouch Pens

What Fiasp® Is and How It Works

Fiasp Flextouch is a rapid‑acting mealtime insulin designed to reduce post‑meal blood glucose. It’s formulated insulin aspart with a vitamin B3 excipient for faster absorption at the injection site. Many adults and adolescents with diabetes use Fiasp Flextouch when a flexible, quick mealtime option fits their care plan. With US delivery from Canada and Canadian pricing, access can be simpler for cash‑pay users, including those buying without insurance.

CanadianInsulin is a prescription referral service. We verify your prescription with your clinic, and licensed Canadian pharmacies dispense your order.

By entering the subcutaneous tissue shortly before eating, Fiasp® begins working quickly to help control the spike that follows meals. Its time‑action profile resembles your body’s early mealtime insulin response. If you’re comparing fast options, you may find our overview on Rapid Acting Insulin helpful.

Who Fiasp® Is For

Fiasp Flextouch is used for adults and children with diabetes who require prandial (mealtime) insulin. It’s commonly combined with a basal insulin or used within multiple daily injection plans or pump therapy (follow the official labeling for pump suitability and directions). Those with known hypersensitivity to insulin aspart or any component should avoid Fiasp.

Use with caution if you have frequent hypoglycemia, changes in kidney or liver function, or if you are pregnant or breastfeeding; the prescriber will weigh benefits and risks and may adjust other diabetes medicines. Talk with your clinician about driving and operating machinery until you know how mealtime insulin affects you.

Dosage and Usage

Mealtime insulin doses are individualized. Prescribers often base the starting dose on current insulin needs, carbohydrate intake, and glycemic goals. Fiasp is typically injected at the start of a meal; per labeling, some patients may dose shortly after the meal begins when directed by their prescriber. Injection sites include abdomen, thigh, upper arm, or buttock, rotating sites to reduce skin changes.

Basic pen steps include: attach a new sterile needle, prime as directed, dial the dose, insert into the skin, press and hold the button for the recommended count, then remove the pen needle and dispose safely. Never share pens or needles.

If switching from another rapid‑acting insulin, follow your clinician’s plan. Dose adjustments may be needed when adding or removing other glucose‑lowering agents.

Strengths and Forms

Fiasp Flextouch pens are prefilled with insulin aspart injection, commonly supplied at 100 units/mL in 3 mL pens, typically packaged as multiple pens per box. Availability can vary by pharmacy. The same formulation is also offered in other presentations, such as cartridges and vials, for patients using reusable pens or syringes.

• Prefilled pen: Flextouch device, ready to use with disposable pen needles
• Cartridge: for compatible reusable pen devices
• Vial: for use with insulin syringes or compatible pumps (follow labeling for pump use)

If you prefer a reusable device, see Fiasp Cartridges. For those drawing doses by syringe, consider Fiasp Vials.

Missed Dose and Timing

For mealtime doses, follow your prescriber’s timing instructions. If a dose is missed and the meal is over, the safest action depends on your plan, current glucose level, and risk of hypoglycemia. Many patients are advised not to “catch up” with large mealtime doses after eating; instead, they may use correction rules provided by their clinician. When unsure, check glucose and follow your care plan or ask your clinic.

Storage and Travel Basics

Unopened pens should be refrigerated per the product label. Once in use, pens are generally kept at room temperature for a limited period; always check the leaflet for the in‑use time window and discard dates. Protect from heat and light. Do not freeze, and do not use if the solution is cloudy or contains particles.

For travel, carry an extra pen, spare needles, and backup supplies in your hand luggage. Keep the original pharmacy label for security checks. Temperature‑sensitive items ship with cold‑chain handling and insulated packaging.

Pen Handling and Sharps Disposal

Use a new sterile needle for every injection. Prime before each dose as directed by the device instructions. Never share your pen or needle with anyone, even if the needle has been changed. After dosing, remove and safely discard the needle in an approved sharps container. When the pen is empty or expired, follow local guidance for disposal.

Benefits

• Rapid mealtime action to address post‑prandial glucose rises
• Flexible dosing window at the start of meals, with label‑supported options for shortly after a meal begins when directed
• Prefilled device with clear dose dial for convenient use
• Compatible with most basal regimens and multiple daily injection plans
• Choice of presentations, including Fiasp Cartridges and Fiasp Vials

Side Effects and Safety

• Common: mild hypoglycemia, injection‑site redness or swelling, headache, nasopharyngitis, cough
• Other: lipodystrophy or skin thickening at injection sites, pruritus, weight changes

Serious but less common risks include severe hypoglycemia, hypokalemia, and allergic reactions. Fluid retention and heart failure can occur when insulin is used with thiazolidinediones. Beta blockers may mask some symptoms of hypoglycemia. Seek emergency care for signs of severe allergy like swelling, rash, or trouble breathing.

Drug Interactions and Cautions

Medicines that may increase hypoglycemia risk with mealtime insulin include other antidiabetic agents (e.g., sulfonylureas), alcohol, and certain antibiotics. Agents that may raise glucose include corticosteroids, some diuretics, and sympathomimetics. Beta blockers can mask adrenergic warning signs. Dose needs may change with renal or hepatic impairment, intense exercise, acute illness, or changes in diet.

Do not dilute or mix Fiasp Flextouch in the pen. If your clinician has instructed mixing with another insulin using a syringe, follow label‑aligned instructions carefully and use separate devices when required.

What to Expect Over Time

With consistent use and dose titration under clinical guidance, many patients see improved post‑meal readings and overall glycemic control. Early weeks often focus on learning device technique, understanding timing around meals, and minimizing lows. Over time, your care team may refine carb ratios, correction factors, and basal/bolus balance.

Compare With Alternatives

Other rapid‑acting insulins used at mealtime include insulin glulisine and insulin lispro. If you and your prescriber are comparing options, you may review Apidra SoloStar Pens and Novorapid Vials. For a head‑to‑head discussion, our article Fiasp Vs Humalog offers practical context.
