About Fiasp Pens

About Fiasp Pens

Fiasp is an insulin that works quickly to manage blood sugar during meals. This medication is known for entering the bloodstream as quickly as within 2.5 minutes after being taken and is used for blood sugar control. Adults and children struggling with diabetes mellitus may be prescribed this medication. This injectable medication is designed to be taken as a meal is being started or up to 20 minutes after that point. This is because the medication has a roughly 15-minute onset time and peaks in about one to three hours.

Fiasp Benefits

  • This medication can be used for improved control when added to existing therapy.
  • Fiasp is flexible and effective to use in children and adolescents.
Fiasp FlexTouch Pens Strengths and Dosages

Fiasp FlexTouch Pens Strengths and Dosages

Fiasp comes in U-100 formulations. It can be used in the form of 10 mL multiple-dose vials or 3 mL single-patient-use FlexTouch pens. It can also be used in the form of 3 mL single-patient-use PenFill cartridges that go into a corresponding compatible device. The number of doses that can be used from one of these devices depends on the dose prescribed to the patient. Dosing for this medication must always be individualized and prescribed by a clinician. Glucose monitoring and the patient’s carbohydrate intake should be factored into the doses decided by the doctor. Fiasp has also been studied for safe use in pediatric patients with type 1 diabetes aged anywhere from 2 years old to 17 years. Pediatric patients in this group may be prescribed this medication with extra blood glucose monitoring and possible dose adjustments.

How to Administer Fiasp

How to Administer Fiasp

This medication may be given to patients in the form of a pen – such as the FlexTouch pen – or a syringe that takes the medication from a vial. Patients using the pen version of the medication should:

  1. Dial the prescribed dose up to 80 units
  2. Insert the needle into the skin
  3. Press the injection button
  4. Wait until the dose counter returns to 0
  5. Keep the needle in the skin for 6 seconds to ensure the full dose is delivered
  6. Remove the needle after 6 seconds (an end of dose click may or may not be hear

This medication may also be available in cartridge form for use with compatible insulin delivery devices, such as the NovoPen Echo or PenFill systems. It can also be used in insulin pumps and in automated insulin delivery systems – including the iLet Bionic Pancreas – when prescribed and set up by a healthcare provider.

Important instructions for pump users:

  • Always keep a backup method for insulin delivery, such as a pen or syringe, in case of pump malfunction or delivery interruption
  • Replace the cartridge at least every four days to help ensure proper insulin delivery if using Fiasp PumpCart cartridges

This insulin should only be used with devices that are specifically approved for compatibility and according to manufacturer and healthcare provider instructions.

Patients using Fiasp should also make sure to:

  • Take Fiasp at mealtime
  • Inject at the first bite of a meal or within 20 minutes after eating begins
  • Choose the delivery method prescribed by the healthcare provider
  • Follow the device-specific instructions before each use
  • Inject under the skin using an approved injection site
  • Rotate injection sites with each dose to reduce skin irritation
  • Monitor blood sugar levels regularly while using Fiasp

Patients using any method of administration should also make sure not to inject their medication into areas of lipohypertrophy. Injection sites should be routinely rotated with each use of the medication.

Safety & Precautions

Safety & Precautions

This medication is not suitable for patients who have blood sugar levels that are too low or have an allergy to the medication or any of its ingredients. Patients should also let their doctor know if they have a personal or family history of some specific issues before starting the medication (as it may impact the suitability and safety of the medication for them). This includes if they have a history of any liver or kidney problems. It also includes whether they are pregnant or breastfeeding. Patients should also let their doctor know of any new prescription or OTC medications that they are taking – including any supplements.

An eye should also be kept out for issues that could develop such as hypoglycemia or hyperglycemia. They should also look out for signs of hypokalemia, ketoacidosis, and fluid retention or heart failure. These conditions are rare but are very serious if they do occur and patients experiencing any of these issues should seek immediate medical attention. Patients should also make sure they undergo stricter glucose monitoring if they are suffering from renal or hepatic impairment and a doctor still prescribes this medication to them.

A blood sugar level below 70 mg/dL is generally considered low and may indicate hypoglycemia. There may be some other signs that a patient has hypoglycemia like:

  • Hunger or nausea
  • Shakiness or trembling
  • Sweating, chills, or cold/clammy skin
  • Nervousness/anxiety or restlessness
  • Irritability
  • Rapid/pounding heartbeat
  • Dizziness or lightheadedness
  • Fatigue
  • Weakness/ lack of energy
  • Drowsiness
  • Pale or washed-out skin tone
  • Headache
  • Blurred or impaired vision
  • Tingling or numb sensations around the face or mouth
  • Trouble with coordination or increased clumsiness
  • Difficulty thinking clearly or confusion
  • Disturbed sleep
  • Seizures (in rare/severe cases)

A patient suffering from hypoglycemia may be able to help with their issues by following the “15-15 rule.” This rule tells patients to:

  1. Check blood glucose levels
  2. Consume 15 fast-acting carbohydrates
  3. Wait 15 minutes before rechecking blood glucose levels
  4. (Only if levels remain low) Those without blood glucose levels that are going up should consume an additional 15 grams of fast-acting carbs
  5. Have a snack made of protein and carbohydrates once blood glucose levels reach the correct levels and another meal is not coming up soon

Patients using this medication should avoid driving or using any heavy machinery until they know how they are affected by using the medication. They should also avoid alcohol consumption and any other medications that may contain alcohol. The use of alcohol increases the risk of hypoglycemia while using this medication.

Needles for this medication must never be shared with other patients. This medication also has contradictions with being used during hypoglycemia episodes or in patients who have a hypersensitivity to any other contents of the medication. It should also not be used by patients with recurrent hypoglycemia or unawareness.

Patients who are going through a sick day should test their blood sugar levels more frequently. This should be done about every four hours. They should otherwise take their medications as normal. It is especially important for this group of patients to also make sure they are staying hydrated. They should also make sure they are not consuming a different amount of food than usual. Sick patients should also continue checking their weight. Weight loss may be a sign of high blood sugar. Body temperature should also be frequently checked to make sure the patient does not develop a fever – an indication of a serious issue or infection.

Patients should not use Fiasp with any drugs that increase the risk of hypoglycemia or impact their blood glucose lower effects of the medication. This medication also interacts with drugs that mask signs and symptoms of hypoglycemia. This includes medications such as beta-blockers or reserpine. It also includes medications like guanethidine and clonidine. Patients combining these medications will need more frequent monitoring of their glucose levels.

Common Side Effects

The use of Fiasp can lead to patients experiencing some common side effects such as:

  • Gradual weight gain in some patients
  • Mild to moderate itching
  • Skin reactions at the injection site (such as redness, rash, or thickening)
  • Eczema flare-ups
  • Small depressions or “pits” where the injection was given
  • Swelling or irritation around the injection site
  • General skin rash

Severe Side Effects

Some patients may also experience more serious effects. Potential serious side effects can include:

  • Drops in blood sugar
  • Low potassium levels
  • Heart failure (especially when taken together with thiazolidinediones)
  • Serious allergic responses involving the entire body

Patients should seek urgent medical care if any serious reactions occur or if common side effects do not improve or become worse.

Overdose/Missed Dose

Overdose/Missed Dose

Patients who miss a dose or accidentally give themselves too low a dose of this medication may have their blood sugar levels become too high (hyperglycemia). Blood sugar levels should be frequently monitored while using this medication and a doctor should be contacted if symptoms or blood sugar levels become concerning. Missed doses should never be made up for by taking an extra dose later on.

Room Temperature Storage (Before First Use)

  • Unopened Fiasp FlexTouch or PenFill medication should be stored in a refrigerator at 36°F to 46°F and may be used until the expiration date before first use (the same goes for the PumpCart version and vials)
  • All Fiasp versions except PumpCart cartridges may be stored up to 86°F for up to 28 days
  • Unopened PumpCart cartridges may be stored up to 86°F for up to 18 days

After First Use

  • FlexTouch pens and vials: refrigerator or room temperature up to 86°F and use within 28 days
  • PenFill cartridges: room temperature only and use within 28 days of opening
  • PumpCart cartridges: room temperature up to 98.6°F and use within 4 days

☀️ Summer Shipping Updates

As we enter the warmer summer months, we are making minor adjustments to our shipping protocols to ensure you receive your medications in the best possible condition.

Due to higher seasonal temperatures during transit, we are implementing the following changes:

  • Adjusted Supply Limits: We will be limiting Cold Chain Medications to 30-day supplies (with the exception of Ozempic, which is available in up to 60-day supplies).
  • Upgraded Packaging: For further security, we are transitioning from our standard medium-sized cold chain boxes to large-sized boxes for all cold chain medications.

Why are we doing this?

While these medications are generally stable at room temperature for 15 to 30 days, shorter shipping cycles and increased insulation mitigate heat exposure. These proactive steps significantly reduce the need for reshipments and guarantee your medication arrives safely.
