Contents of the pack
Fiasp is an insulin that is administered at mealtimes with a rapid effect of lowering blood sugar. Fiasp is an injectable solution 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 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 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, shrinkage 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 change in the injection site. 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 check your blood sugar levels more closely and adjust the insulin or the 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 need for insulin, 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 a low blood sugar level (hypoglycemia) is especially important for the health of your baby. After having your baby, your insulin requirements 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 levels can affect your ability to drive or use tools or machines. If you have a low blood sugar level, your concentration and reaction 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

Before using Fiasp for the first time, your doctor or nurse will show you how to do it. Consult your doctor if you need to inject the insulin by another method.
Where to inject
Do not use Fiasp
How to inject Fiasp
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 level".
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 level".
Three simple steps that can help you avoid low or high blood sugar levels:
If you stop treatment with 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 problem that consists of an excess of acid in the blood that is potentially fatal). See symptoms and recommendations in section 4 "High blood sugar level".
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 have symptoms of low blood sugar, take measures to increase your blood sugar level immediately. See the recommendations "Low blood sugar level" below.
If you suffer a severe allergic reaction(including anaphylactic shock) to insulin or any of the components of Fiasp (the frequency at which this occurs 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 no improvement is seen within a few weeks.
Changes in the skin at the injection siteIf 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 at which this occurs 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 feeling of tiredness, 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:
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, which 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 tiredness,
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.
