Patient Medication Information: uses, side effects, how to take - Icatibant Injection (Accord Healthcare)

What is ICATIBANT INJECTION used for?

ICATIBANT INJECTION is used to treat acute attacks of hereditary angioedema (HAE) in:

  • adults,
  • adolescents, and
  • children aged 2 years and older

with a deficiency of a protein called C1-esterase inhibitor.

How does ICATIBANT INJECTION work?

In HAE, levels of a substance in your bloodstream called bradykinin are increased. This can cause swelling, pain, nausea, and diarrhea. ICATIBANT INJECTION blocks the activity of bradykinin. This stops the symptoms of an HAE attack from getting worse.

What are the ingredients in ICATIBANT INJECTION?

Medicinal ingredients: icatibant, as icatibant acetate

Non-medicinal ingredients: glacial acetic acid, sodium chloride, sodium hydroxide, and water for injection

ICATIBANT INJECTION comes in the following dosage forms:

Solution for injection, 30 mg / 3 mL (10 mg / mL)

Do not use ICATIBANT INJECTION if:

  • you or your child are allergic to icatibant acetate or to any ingredient in this medicine.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take ICATIBANT INJECTION. Talk about any health conditions or problems you may have, including if you:

  • have heart problems such as unstable angina (reduced blood flow to the heart muscle)
  • have recently suffered a stroke
  • are pregnant or plan to become pregnant
  • are breastfeeding or plan to breastfeed

Other warnings you should know about:

  • Only a doctor who has experience treating patients with HAE is recommended to treat you or your child with ICATIBANT INJECTION.

Caregivers/Self-administration:

  • You or your child’s first injection of ICATIBANT INJECTION should be given under the guidance of a healthcare professional. Your healthcare professional will tell you when it is safe to go home.
  • You or your caregiver may inject ICATIBANT INJECTION only after receiving training on how to use it. A healthcare professional will teach you and your caregiver how to use it.
  • Self-injection for children is not recommended. ICATIBANT INJECTION should only be given to children by a healthcare professional or caregiver.
  • Adolescents may only self-inject if their doctor and caregiver agree that it is appropriate for them to do so.

Laryngeal HAE attacks:

  • A laryngeal HAE attack, or an attack of the throat, can become life threatening. This is because increased swelling of the throat can create a blockage of the upper airway. This in turn makes breathing difficult.

  • If you or your child have a laryngeal HAE attack:

    • inject ICATIBANT INJECTION, and
    • go to the nearest hospital emergency room for medical help right away.
  • A blockage of the airway may occur faster in children and adolescents than in adults. This is because the airway passage is smaller in these patients.

Adolescents and Children:

  • ICATIBANT INJECTION is not recommended for use in children under 2 years of age or those who weigh less than 12 kg

  • There is limited experience with the use of ICATIBANT INJECTION in the treatment of:

    • children under 6 years of age
    • laryngeal HAE attacks in adolescents and children

Effects on Reproductive Organs in Adolescents and Children aged 2 years and above

  • The effects of long-term ICATIBANT INJECTION use are not known.
  • Early studies have shown that when icatibant is used often, it may cause damage to the reproductive system or may affect how it develops.
  • Your healthcare professional may do blood tests to check how your or your child’s reproductive organs are working.

Pregnancy and Breastfeeding:

  • It is not known if ICATIBANT INJECTION will harm your unborn baby. If you are pregnant or planning to become pregnant, speak to your doctor before using ICATIBANT INJECTION. You and your doctor will decide if ICATIBANT INJECTION is right for you.
  • It is not known if ICATIBANT INJECTION passes into breast milk. If you are breast-feeding or planning to breast-feed, speak to your doctor before using ICATIBANT INJECTION about the best way to feed your baby.

Driving and Using Machinery

  • ICATIBANT INJECTION may cause tiredness, dizziness or sleepiness. DO NOT drive or operate machinery after using ICATIBANT INJECTION if you feel tired or dizzy.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

The following may interact with ICATIBANT INJECTION:

  • Angiotensin converting enzyme (ACE) inhibitor (used to lower blood pressure)

How to take ICATIBANT INJECTION:

  • You or your caregiver may inject ICATIBANT INJECTION only after receiving training on how to use it.
  • Always use ICATIBANT INJECTION exactly as your healthcare professional has shown you.
  • Be sure to use each ICATIBANT INJECTION prefilled syringe only once, even if there is still medicine in it.

  • ICATIBANT INJECTION is given as a single injection under the skin on the stomach. This is called a subcutaneous injection.

    • In adults and adolescents who weigh more than 65 kg:

      • The ICATIBANT INJECTION prefilled syringe will be used to give the injection.

    • In adolescents who weigh 65 kg or less and children aged 2 years and above:

      • Some ICATIBANT INJECTION will need to be transferred from the prefilled syringe into an empty graduated syringe. This graduated syringe will then be used to inject ICATIBANT INJECTION.

Read and follow the below STEP-BY-STEP INSTRUCTIONS FOR INJECTION. It will take you through the process to give a ICATIBANT INJECTION.
