Read all of this leaflet carefully before you start using this medicine because it contains important information for you.
Contents of the pack
Fiasp is an insulin that is administered at mealtimes with a rapid effect of lowering blood sugar. Fiasp is a solution for injection of insulin aspart and is used to treat diabetes mellitus in adults, adolescents, and children from 1 year of age. Diabetes is a disease in which the body does not produce enough insulin to control blood sugar levels. Treatment with Fiasp helps to prevent complications of diabetes. Fiasp should be injected from 2 minutes before starting to eat, with the possibility of administration up to 20 minutes after the start of the meal. This medicine reaches its maximum effect between 1 and 3 hours after injection and the effect lasts between 3 and 5 hours.
This medicine should normally be used in combination with intermediate-acting or long-acting insulins.
Do not use Fiasp
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to use Fiasp. It is important that you know the following:
In case of reduced vision, see section 3 "How to use Fiasp".
Certain conditions and activities can affect your insulin requirements. Consult your doctor:
When using Fiasp, it is strongly recommended that you record the name and batch number of each pack to keep a record of the batches used.
Changes in the skin at the injection site
The injection site should be rotated to help avoid changes in the fatty tissue, such as thickening of the skin, shrinking of the skin, or lumps under the skin. Insulin may not work very well if it is injected into a swollen, shrunk, or thickened area (see section 3 "How to use Fiasp"). Inform your doctor if you detect any changes in the injection area. Inform your doctor if you are currently injecting into these affected areas, before starting to inject into a different area. Your doctor may indicate that you should check your blood sugar levels more closely and adjust the insulin or dose of your other antidiabetic medications.
Children and adolescents
This medicine is not recommended for use in children under 1 year of age.
Other medicines and Fiasp
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines. Some medicines affect your blood sugar level and this may mean that you need to change your insulin dose.
The following are the main medicines that can affect your treatment with insulin.
Your blood sugar level may decrease (hypoglycemia) if you take:
Your blood sugar level may increase (hyperglycemia) if you take:
Octreotide and lanreotide, used to treat acromegaly, a rare disorder characterized by excessive production of growth hormone. These medicines may increase or decrease your blood sugar level.
If you are in any of the above situations (or are unsure), consult your doctor or pharmacist.
Using Fiasp with alcohol
If you drink alcohol, it may change your insulin needs, as your blood sugar level may be increased or decreased. Therefore, you should check your blood sugar level more frequently than usual.
Pregnancy and breastfeeding
If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine. This medicine can be used during pregnancy, however, it may be necessary to modify the insulin dose while you are pregnant and after delivery. The amount of insulin you need usually decreases during the first 3 months of pregnancy and increases during the remaining 6 months. During pregnancy, careful control of your diabetes is necessary. Avoiding low blood sugar (hypoglycemia) is especially important for the health of your baby. After having your baby, your insulin needs will probably return to what they were before pregnancy.
There are no restrictions on the use of Fiasp during the breastfeeding period.
Driving and using machines
Low blood sugar can affect your ability to drive or use tools or machines. If you have low blood sugar, your ability to concentrate and react may be affected. This could put your life or the lives of others at risk. Ask your doctor if you can drive if:

Injecting Fiasp
This medicine is only intended for injection under the skin (subcutaneous injection).
Before using Fiasp for the first time, your doctor or nurse will show you how to use the pre-filled pen. Consult your doctor if you need to inject the insulin by another method.
Where to inject
Do not use Fiasp
Detailed instructions on how to use the FlexTouch pen are provided on the other side of this leaflet
If you use more Fiasp than you should
If you use too much insulin, your blood sugar level may become very low (hypoglycemia), see section 4 "Low blood sugar".
If you forget to use Fiasp
If you forget to inject the insulin, your blood sugar level may become very high (hyperglycemia). See section 4 "High blood sugar".
Three simple steps that can help you avoid low or high blood sugar levels:
If you stop using Fiasp
Do not stop your insulin treatment without consulting your doctor. Stopping the administration of insulin could cause a very high blood sugar level (severe hyperglycemia) and ketoacidosis (a potentially fatal condition that consists of an excess of acid in the blood). See symptoms and recommendations in section 4 "High blood sugar".
Like all medicines, this medicine can cause adverse effects, although not all people suffer from them.
Low blood sugar level (hypoglycemia)is a very frequent adverse effect of insulin treatment (it can affect more than 1 in 10 people). It can be very serious. A severe drop in blood sugar can lead to loss of consciousness. Severe hypoglycemia can cause brain damage and put your life at risk. If you experience symptoms of low blood sugar, take measures to increase your blood sugar level immediately. See the recommendations "Low blood sugar level" below.
If you experience a severe allergic reaction(including anaphylactic shock) to insulin or any of the components of Fiasp (the frequency of which is unknown), discontinue treatment with this medicine and contact the emergency medical service immediately.
The symptoms of a severe allergic reaction may include:
Allergic reactionssuch as widespread skin rash and facial swelling may occur. These are uncommon and may affect up to 1 in 100 people. Consult a doctor if symptoms worsen or if you see no improvement within a few weeks.
Changes in the skin at the injection site:If insulin is injected in the same place, the fatty tissue can shrink (lipoatrophy) or become thicker (lipohypertrophy) (these are uncommon and may affect up to 1 in 100 people). Lumps under the skin can also occur due to the accumulation of a protein called amyloid (cutaneous amyloidosis; the frequency of which is unknown). Insulin may not work very well if injected into a lumpy, shrunken, or thickened area. Change the injection site to help avoid these skin changes.
Other adverse effects include:
Frequent(may affect up to 1 in 10 people)
Reaction at the administration site: Localized reactions may appear at the injection site. Symptoms may include: rash, redness, inflammation, bruising, irritation, pain, and itching. These reactions usually disappear after a few days.
Skin reactions: Signs of skin allergy such as eczema, rash, itching, hives, and dermatitis may appear.
General effects of insulin treatment, including Fiasp
Low blood sugar levels may occur if:
You drink alcohol, inject too much insulin, exercise more than usual, eat very little, or skip a meal.
Warning symptoms of low blood sugar, which can appear suddenly:Headache, difficulty speaking, palpitations, cold sweat, cold and pale skin, nausea, excessive hunger, trembling, nervousness or anxiety, unusual fatigue, weakness, and drowsiness, confusion, difficulty concentrating, temporary changes in vision.
What to do if your blood sugar level is low
What people close to you should do if you lose consciousness
Inform the people you spend time with that you have diabetes. Tell them what the consequences of low blood sugar might be, including the risk of losing consciousness.
Tell them that if you become unconscious, they should do the following:
You may regain consciousness more quickly if someone who knows how to do so administers a glucagon injection to you.
If severe hypoglycemia is not treated, it can cause brain damage over time. This can be temporary or permanent. It can even lead to death.
Talk to your doctor if:
You may need to adjust the dose or frequency of your insulin injections, diet, or exercise.
High blood sugar levels may occur if:
You eat more or exercise less than usual, drink alcohol, have an infection or fever, do not inject enough insulin, repeatedly inject less insulin than you need, forget to inject insulin, or interrupt your insulin treatment.
Warning symptoms of high blood sugar, which usually appear gradually:Redness of the skin, dry skin, feeling of drowsiness or fatigue, dry mouth, fruity breath odor (acetone), increased need to urinate, thirst, loss of appetite, nausea, or vomiting.
These can be symptoms of a very serious condition called ketoacidosis. It is an accumulation of acid in the blood because the body is metabolizing fat instead of sugar. If left untreated, it can lead to diabetic coma and even death.

Instructions for Using Fiasp FlexTouch
Read these instructions carefullybefore using your pre-filled FlexTouch pen. If you do not follow the instructions carefully, you may administer too little or too much insulin, which could lead to high or low blood sugar levels.
Do not use the pen without proper trainingfrom your doctor or nurse.
Start by checking the pen to make sure it contains Fiasp 100units/mland then look at the illustrations to familiarize yourself with the different parts of the pen and needle.
If you are blind or have reduced vision and cannot read the dose counter on the pen, do not use this pen without assistance.Seek help from a person without visual problems and who is trained in the use of the pre-filled FlexTouch pen.
Your pen is a pre-filled insulin dosing pen that contains 300 units of insulin. You can select a maximum of 80units per dose in increments of 1unit.Your pen is designed to be used with disposable, single-use injectable needles between 4 mm and 8 mm in length and a gauge between 30 G and 32 G. Needles are not included in the container.
Important Information
Pay special attention to these notes because they are important for the correct use of the pen.

1 Preparing the Pen with a New Needle

Look through the insulin window. If the insulin appears cloudy, do not use the pen.


Make sure to place the needle correctly.

The needles are covered by two caps. You must remove both caps.If you forget to remove both, you will notinject any insulin.

A drop of insulin may appear at the tip of the needle. This is normal, but you must still check the insulin flow.
Do not put a new needleon the pen until you are ready to take the injection.

Always use a new needlefor each injection.
This reduces the risk of contamination, infection, loss of insulin, needle blockage, and inaccurate dosing.
Never use a bent or damaged needle.
2 Checking the Insulin Flow
This will help ensure you receive the full insulin dose.

Gently tap the top of the penseveral times to make any air bubbles rise.

The 0 must be aligned with the dose marker.
A drop of insulin must appear at the tip of the needle.

A small air bubble may remain at the tip of the needle, but it will not be injected.
If a drop does not appear,repeat steps 2A to 2C up to 6 times. If a drop still does not appear, change the needle and repeat steps 2A to 2C once more.
If, despite this, a drop of insulin does not appear, discard the pen and use a new one.
Always make sure a drop appearsat the tip of the needle before injecting. This ensures the insulin is flowing correctly.
If a drop does not appear, no insulin will be injected, even if the dose counter moves. This may indicate that the needle is blocked or damaged.
Always check the insulin flow before injecting.If you do not check the flow, you may receive too little or no insulin. This could lead to high blood sugar levels.
3 Selecting the Dose
The 0 must be aligned with the dose marker.
If you have selected a wrong dose, you can turn the dose selector forward or backward until you select the correct dose.
The pen can select up to a maximum of 80 units.

The dose selector changes the number of units. Only the dose counter and dose marker show how many units you have selected for each administration.
You can select up to 80 units per administration. When the pen contains less than 80 units, the dose counter stops when it reaches the number of units left.
Always use the dose counter and dose marker to see how many units you have selected.
Do notcount the pen's clicks to set the dose. If you select a wrong dose and inject it, your blood sugar level may become too high or too low.
Do not use the insulin scale, as it only indicates the approximate amount of insulin left in the pen.
The dose selector clicks differently when turned forward, backward, or when passing the number of units left.
4 Injecting the Dose
Do not touch the dose counter with your fingers. This could interrupt the injection.

The 0 must be aligned with the dose marker. You may hear or feel a click.


If you see blood at the injection site, press the skin gently for a few minutes to stop the bleeding. Do not rub the area.

A drop of insulin may appear at the tip of the needle after the injection. This is normal and does not affect the dose.
Always watch the dose counter to know how many units you are injecting.Keep the dose button pressed until the dose counter shows 0. If the dose counter does not return to 0, it means you have not received the full dose, which could result in high blood sugar levels.
How to detect if the needle is blocked or damaged?
What to do if the needle is blocked?
Remove the needle as described in section 5 and repeat all the steps from section 1: Preparing the pen with a new needle. Make sure to select the full dose you need.
Never touch the dose counter while injecting.
This can interrupt the injection.
5 After the Injection
Always discard the needle after each injection.
This reduces the risk of contamination, infection, loss of insulin, needle blockage, and inaccurate dosing. If the needle is blocked, noinsulin will be injected.



When the pen is empty, discard it withoutthe needle attached, following the instructions of your doctor, nurse, pharmacist, or local authorities.
Never try to put the inner needle cap back on.You could prick yourself or damage it.
Always remove the needle from the pen after each injectionand store your pen without the needle attached. This reduces the risk of contamination, infection, loss of insulin, needle blockage, and inaccurate dosing.
6 How Much Insulin is Left?

Turn the dose selector until the dose counter stops.
If it shows 80, it means there are at least 80unitsleft in the pen.
If it shows less than 80,the number shows the amount of units left in the pen.

Be very careful when doing the calculation if you divide your dose.
If you are not sure, inject the full dose with a new pen. If you incorrectly divide the dose, you may inject too little or too much insulin, which can lead to high or low blood sugar levels.
