Fiasp® Flextouch Insulin Pen for Diabetes

Fiasp® Flextouch is a prefilled insulin aspart U-100 pen for mealtime blood sugar control. CanadianInsulin connects patients to Canadian pharmacies with US delivery from Canada and Canadian pricing. You can order online and pay out of pocket without insurance.

What Fiasp® Is and How It Works

Fiasp is insulin aspart injection 100 units/mL formulated with niacinamide to speed absorption and L-arginine to stabilize the solution. As a rapid-acting mealtime insulin, it starts working quickly to cover food and correct high readings. Novo Nordisk supplies this medicine in the Flextouch pen for accurate, convenient dosing. At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic.

Insulin aspart lowers blood sugar by enabling glucose uptake into muscle and fat and by reducing liver glucose output. Most people use Fiasp with a separate basal insulin as part of a multiple daily injection plan. If you want background on how this formulation compares to another aspart option, see Difference Between Fiasp Novolog.

Who Fiasp Is For

Fiasp Flextouch is used by adults and children with diabetes mellitus who need a rapid-acting mealtime insulin. It is appropriate for type 1 diabetes and for type 2 diabetes when prandial insulin is prescribed. Do not use if you have had an allergic reaction to insulin aspart or any pen component. Avoid injecting during episodes of low blood sugar. The pen is not for intravenous use and is not for treatment of diabetic ketoacidosis.

Dosage and Usage

Use Fiasp exactly as prescribed. Typical timing is at the start of a meal or within 20 minutes after starting a meal. Doses are individualized based on carbohydrate intake, blood glucose targets, and your insulin-to-carbohydrate ratio and correction factor. Many patients use Fiasp for meals plus a separate basal insulin once or twice daily. Your clinician may recommend subcutaneous injection into the abdomen, thigh, or upper arm. Rotate injection sites to reduce skin changes. Insulin pumps may be an option for Fiasp using appropriate supplies; the prefilled Flextouch pen itself is for injections only. Monitor blood glucose regularly and follow your care plan when adjusting dose for activity or illness.

Missed Dose and Timing

If you miss a mealtime dose, check your blood glucose and follow your care plan. Inject as soon as practical at the start of a meal or within 20 minutes after starting a meal, unless your clinician advised differently. Do not inject for a meal you will not eat. If you are unsure how to correct, contact your diabetes team.

Storage and Travel Basics

Unopened Fiasp Flextouch pens are typically stored in a refrigerator between 2°C and 8°C. Do not freeze and do not use if frozen. Protect from excessive heat and light. Once in use, a pen can be kept at room temperature as directed in the label, usually up to 28 days. Keep the cap on when not in use. Do not store a pen with a needle attached. For travel, carry pens and supplies in an insulated case and keep them with you in a cabin bag, not in checked luggage. CanadianInsulin uses prompt, express, cold-chain shipping for insulin orders.

Pen Handling and Sharps Disposal

Review the pen instructions before first use. Attach a new sterile needle for each injection. Prime the pen per the instructions to see a drop at the needle tip. Dial the dose in whole-unit steps. Insert the needle into the recommended injection site and press the button until the counter returns to zero. Keep the needle in place for a few seconds, then remove it. Remove and safely discard the needle after each injection. Never share your pen or needles. Dispose of needles and used sharps in an FDA-cleared sharps container or a sturdy household container if allowed locally. Follow community rules for sharps collection.

Benefits

Fiasp Flextouch is designed for mealtime control. It is a rapid-acting insulin that you can take at the start of a meal or shortly after starting one, which offers practical flexibility. The prefilled pen is ready to use, with clear unit markings and a low injection force. Many patients value the portability of a 3 mL insulin aspart 100 units/mL pen for daily life and travel.

Side Effects and Safety

• Low blood sugar (shakiness, sweating, fast heartbeat, confusion)
• Injection site reactions such as redness, swelling, or itching
• Skin changes at injection sites (lipodystrophy or localized thickening)
• Weight gain over time
• Mild rash
• Fluid retention, especially when used with thiazolidinediones

Serious effects can include severe hypoglycemia that requires help, allergic reactions, and low potassium. The risk of low blood sugar increases if you skip meals, inject too much, exercise more than usual, or combine with other glucose-lowering drugs that can cause hypoglycemia. Seek urgent care for signs of severe reaction. For a deeper overview of labeled uses and safety, read Fiasp Uses Side Effects Dosage.

Drug Interactions and Cautions

Medicines that can increase or decrease insulin needs include corticosteroids, some diuretics, thyroid medicines, oral contraceptives, atypical antipsychotics, and some antivirals. Other diabetes medicines, such as sulfonylureas and SGLT2 inhibitors, may raise hypoglycemia risk when combined with insulin. GLP-1 therapies may change dose needs as eating patterns change. Beta blockers can mask symptoms of hypoglycemia such as tremor or palpitations. Alcohol increases the risk of low blood sugar. Discuss all medicines, vitamins, and supplements with your clinician and pharmacist.

What to Expect Over Time

With correct use, Fiasp Flextouch helps limit post-meal glucose spikes. Day-to-day results can vary with meals, activity, and stress. Your clinician will guide dose adjustments based on glucose logs and targets. Over months, improved mealtime control can support better A1C, along with nutrition and basal insulin adjustments.

Compare With Alternatives

Other rapid-acting insulin options are available. Insulin glulisine is supplied as Apidra® SoloStar Pens, which many patients use as a mealtime insulin. Insulin aspart is also marketed as NovoRapid® Vials in some regions. Insulin lispro (Humalog) is another well-known rapid-acting alternative. Your prescriber can help select the product that fits your regimen and devices.

Many patients use a 5 x 3 mL carton of Fiasp Flextouch pens to cover several weeks of mealtime doses. You can also order insulin aspart pens from Canada as part of a larger refill plan to reduce trips and simplify schedules.

Availability and Substitutions

Availability can vary. If Fiasp Flextouch is not available, your prescriber may recommend a therapeutic alternative or a different presentation, such as a vial or cartridge. Follow your clinician’s advice before switching between brands or forms.

Patient Suitability and Cost Saving Tips

Fiasp Flextouch suits patients who need rapid-acting coverage for meals. People with frequent unexplained lows, significant vision or dexterity challenges, or a history of severe reactions need extra care when using pen devices. Discuss kidney or liver issues, pregnancy plans, and all current medicines before starting.

To save on costs, consider multi-month quantities if your prescription allows. Set refill reminders so you do not run out. Keep a spare pen available for travel and work. Combine your order with other supplies to simplify shipping. Review Canadian pricing and select pack sizes that match your usage pattern.
