Trurapi is a modern insulin (insulin analogue) with a rapid-acting effect. Modern insulin products are improved versions of human insulin.
Trurapi is used to reduce the high blood sugar level in adults, adolescents and children aged 1 year and above with diabetes mellitus (diabetes). Diabetes is a disease where your body does not produce enough insulin to control the level of your blood sugar. Treatment with insulin aspart helps to prevent complications from your diabetes.
Insulin aspart will start to lower your blood sugar 10–20 minutes after you inject it, a maximum effect occurs between 1 and 3 hours after the injection and the effect lasts for 3–5 hours.
Due to this short action insulin aspart should normally be taken in combination with intermediate-acting or long-acting insulin preparations. Moreover, Trurapi can be used for continuous subcutaneous infusion in a pump system.
If any of these applies, do not use Trurapi. Talk with your doctor, nurse or pharmacist for advice.
Record the brand name (“Trurapi”) and Lot number (included on the outer carton and label of each vial) of the medicine you are using and provide this information when reporting any side effects.
Skin changes at the injection site
The injection site should be rotated to prevent skin changes such as lumps under the skin. The insulin may not work very well if you inject into a lumpy area (see “How to use Trurapi”). Contact your doctor if you are currently injecting into a lumpy area before you start injecting in a different area. Your doctor may tell you to check your blood sugar more closely, and to adjust your insulin or your other antidiabetic medications dose.
Some conditions and activities can affect your need for insulin. Consult your doctor:
Do not give this medicine to children below 1 year of age since no clinical trials have been carried out in children below the age of 1 year.
Tell your doctor, nurse or pharmacist if you are taking, have recently taken or might take any other medicines.
Some medicines affect your blood sugar level and this may mean that your insulin dose has to change. Listed below are the most common medicines which may affect your insulin treatment.
Your blood sugar level may fall (hypoglycaemia) if you take:
Your blood sugar level may rise (hyperglycaemia) if you take:
Octreotide and lanreotide (used for treatment of acromegaly, a rare hormonal disorder that usually occurs in middle-aged adults, caused by the pituitary gland producing excess growth hormone) may either increase or decrease your blood sugar level.
Beta–blockers (used to treat high blood pressure) may weaken or suppress entirely the first warning symptoms which help you to recognise low blood sugar.
Pioglitazone (tablets used for the treatment of type 2 diabetes)
Some patients with long–standing type 2 diabetes and heart disease or previous stroke who were treated with pioglitazone and insulin experienced the development of heart failure. Inform your doctor as soon as possible if you experience signs of heart failure such as unusual shortness of breath or rapid increase in weight or localised swelling (oedema).
If you have taken any of the medicines listed here, tell your doctor, nurse or pharmacist.
If you drink alcohol, your need for insulin may change as your blood sugar level may either rise or fall. Careful monitoring is recommended.
If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine. Insulin aspart can be used during pregnancy.
Your insulin dose may need to be changed during pregnancy and after delivery. Careful control of your diabetes, particularly prevention of hypoglycaemia, is important for the health of your baby.
There are no restrictions on treatment with insulin aspart during breast-feeding.
Ask your doctor, nurse or pharmacist for advice before using this medicine while pregnant or breast-feeding.
Please ask your doctor whether you can drive a car or use a machine:
If your blood sugar is low or high, your concentration and ability to react might be affected and therefore also your ability to drive or use a machine. Bear in mind that you could endanger yourself or others.
Trurapi has a rapid onset of effect therefore if hypoglycaemia occurs, you may experience it earlier after an injection when compared to soluble human insulin.
This medicine contains less than 1 mmol (23 mg) sodium per dose, that is to say essentially “sodium-free”.
Always use your insulin and adjust your dose exactly as your doctor has told you. Check with your doctor, nurse or pharmacist if you are not sure.
Insulin aspart is generally used immediately before a meal. Eat a meal or snack within 10 minutes of the injection to avoid low blood sugar. When necessary, insulin aspart can be given soon after a meal (see “How and where to inject” below for information).
Do not change your insulin unless your doctor tells you to. If your doctor has switched you from one type or brand of insulin to another, your dose may have to be adjusted by your doctor.
Insulin aspart can be used in adolescents and children aged 1 year and above instead of soluble human insulin when a rapid onset of effect is preferred. For example, when it is difficult to dose the child in relation to meals.
If you have reduced kidney or liver function, or if you are above 65 years of age, you need to check your blood sugar more regularly and discuss changes in your insulin dose with your doctor.
Trurapi is for injection under the skin (subcutaneously) or for continuous subcutaneous infusion in a pump system.
Administration in a pump system will require a comprehensive instruction by your healthcare professional. You must never inject yourself directly into a vein (intravenously) or muscle (intramuscularly).
If necessary, Trurapi can be given directly into a vein but this must only be done by physicians or other healthcare staff.
With each injection, change the injection site within the particular area of skin that you use. This may reduce the risk of developing lumps or skin pitting (see section 4 “Possible side effects”). The best places to give yourself an injection are: the front of your waist (abdomen), the upper arm or the front of your thighs. The insulin will work more quickly if you inject into the front of your waist (abdomen). You should always measure your blood sugar regularly.
1. Draw into the syringe the same amount of air as the dose of insulin you are going to inject. Inject the air into the vial.
2. Turn the vial and syringe upside down and draw the correct insulin dose into the syringe. Pull the needle out of the vial. Then expel the air from the syringe and check that the dose is correct.
Trurapi should never be mixed with any other insulin when used in a pump.
Follow the instructions and recommendations from your doctor regarding the use of Trurapi in a pump.
Before use of Trurapi in the pump system, you must have received a comprehensive instruction in the use and information about any actions to be taken in case of illness, too high or too low blood sugar or failure of the pump system.
To get the benefit of insulin infusion, and to detect possible malfunction of the insulin pump, it is recommended that you measure your blood sugar level regularly.
You should always have an alternative delivery method for your insulin available for injection under the skin in case of pump system failure.
If you use too much insulin your blood sugar gets too low (hypoglycaemia) (see “Summary of serious and very common side effects” in section 4).
If you forget to use your insulin your blood sugar may get too high (hyperglycaemia) (see “Effects from diabetes” in section 4).
Do not stop using your insulin without speaking with a doctor, who will tell you what needs to be done.
This could lead to very high blood sugar (severe hyperglycaemia) and ketoacidosis (see “Effects from diabetes” in section 4).
If you have any further questions on the use of this medicine, ask your doctor, nurse or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Low blood sugar (hypoglycaemia) is a very common side effect. It may affect more than 1 in 10 people.
Low blood sugar may occur if you:
Signs of low blood sugar: Cold sweat; cool pale skin; headache; rapid heartbeat; feeling sick; feeling very hungry; temporary changes in vision; drowsiness; unusual tiredness and weakness; nervousness or tremor; feeling anxious; feeling confused; difficulty in concentrating.
Severe low blood sugar can lead to unconsciousness. If prolonged severe low blood sugar is not treated, it can cause brain damage (temporary or permanent) and even death. You may recover more quickly from unconsciousness with an injection of the hormone glucagon by someone who knows how to use it. If you are given glucagon you will need glucose or a sugar snack as soon as you are conscious. If you do not respond to glucagon treatment, you will have to be treated in a hospital.
What to do if you experience low blood sugar:
Tell relevant people that you have diabetes and what the consequences may be, including the risk of passing out (become unconscious) due to low blood sugar. Let them know that if you pass out, they must turn you on your side and get medical help straight away. They must not give you any food or drink due to risk of suffocation.
Serious allergic reactions to Trurapi or one of its ingredients (called a systemic allergic reaction) is a very rare side effect but can potentially be life-threatening. It may affect up to 1 in 10,000 people.
Seek medical advice immediately:
If you notice any of these signs, seek medical advice immediately.
Skin changes at the injection site:
If you inject insulin too often at the same place, the fatty tissue under the skin at the injection site may shrink (lipoatrophy) or thicken (lipohypertrophy) (may affect up to 1 in 100 people). Lumps under the skin may also be caused by build-up of a protein called amyloid (cutaneous amyloidosis; how often this occurs is not known). The insulin may not work very well if you inject into a lumpy area. Change the injection site with each injection to help prevent these skin changes. If you notice your skin pitting or thickening at the injection site, tell your doctor or nurse. These reactions can become more severe, or they may change the absorption of your insulin, if you inject in such a site.
Uncommon (may affect up to 1 in 100 people)
Signs of allergy: Local allergic reactions(pain, redness, hives, inflammation, bruising, swelling and itching) at the injection site may occur. These usually disappear after a few weeks of using your insulin. If they do not disappear, or if they spread throughout your body, talk to your doctor immediately (see also “Serious allergic reactions” above).
Vision problems: When you first start your insulin treatment, it may disturb your vision, but the disturbance is usually temporary.
Swollen joints: When you start using insulin, water retention may cause swelling around your ankles and other joints. Normally this soon disappears. If not, talk to your doctor.
Diabetic retinopathy (an eye disease related to diabetes which can lead to loss of vision):
If you have diabetic retinopathy and your blood sugar level improves very fast, the retinopathy may get worse.
Ask your doctor about this.
Rare side effects (may affect up to 1 in 1,000 people).
Painful neuropathy (pain due to nerve damage): If your blood sugar level improves very fast, you may get nerve-related pain. This is called acute painful neuropathy and is usually transient.
If you get any side effects, talk to your doctor, nurse or pharmacist. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.
High blood sugar (hyperglycaemia)
High blood sugar may occur if you:
Warning signs of high blood sugar:
The warning signs appear gradually. They include: increased urination; feeling thirsty; losing your appetite; feeling sick (nausea or vomiting); feeling drowsy or tired; flushed; dry skin; dry mouth and a fruity (acetone) smell of the breath.
