What is Berinert used for?

Berinert is used for the treatment and pre-procedure prevention of the hereditary angioedema type I and II (HAE, oedema = swelling).

HAE is a congenital disease of the vascular system. It is a non-allergic disease. HAE is caused by deficiency, absence or defective synthesis of C1-esterase inhibitor, an important protein. The illness is characterised by the following symptoms:

– swelling of the hands and feet that occurs suddenly,

– facial swelling with tension sensation that occurs suddenly,

– eyelid swelling, lip swelling, possibly laryngeal (voice box) swelling with difficulty in breathing,

– tongue swelling,

– colic pain in abdominal region.

Generally, all parts of the body can be affected.

2. what you need to know before you use berinert

The following sections contain information that your doctor should consider before you are given Berinert.

Do not use Berinert:

  • if you are allergic to the protein C1-esterase inhibitor or any of the other ingredients of this medicine listed in section 6.

Please inform your doctor or pharmacist if you are allergic to any medicine or food.

REG-5293–01 (28)

Warnings and precautions:

  • if you have experienced allergic reactions to Berinert in the past. You should take antihistamines and corticosteroids prophylactically if advised by your doctor.
  • when allergic or anaphylactic-type reactions occur (a serious allergic reaction that causes severe difficulty in breathing or dizziness).

The administration of Berinert should then be stopped immediately (e.g. discontinue injection)

  • if you suffer from laryngeal swelling (laryngeal oedema). You should be carefully monitored with emergency treatment in stand-by
  • during unlicensed use beyond the approved indications and posology (e.g. Capillary Leak Syndrome, CLS). See section 4. “Possible side effects”.

Your doctor will consider carefully the benefit of treatment with Berinert compared with the risk of these complications.

Virus safety

  • When medicines are made from human blood or plasma, certain measures are put in place to prevent infections being passed on to patients. These include: careful selection of blood and plasma donors to make sure those at risk of carrying infections are excluded, and
  • the testing of each donation and pools of plasma for signs of virus/ infections.

Manufacturers of these products also include steps in the processing of the blood or plasma that can inactivate or remove viruses. Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of passing on infection cannot be totally excluded. This also applies to any unknown or emerging viruses or other types of infections.

The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV, the AIDS virus), hepatitis B virus, hepatitis C virus (inflammation of the liver) and for the non-enveloped viruses hepatitis A (inflammation of the liver) and parvovirus B19.

Your doctor may recommend that you consider vaccination against hepatitis A and B if you regularly/repe­atedly receive human plasma-derived products.

It is strongly recommended that every time that Berinert is given, the date of administration, the batch number and the injected volume should be recorded.

Other medicines and Berinert

  • Please tell your doctor or pharmacist if you are taking or have recently taken any medicines, including medicines obtained without a prescription.
  • Berinert should not be mixed with other medicinal products and diluents in the syringe/infusi­on set.
  • If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
  • During pregnancy and breast-feeding Berinert should be given only if it is clearly needed.

Reconstitution and method of administration

Berinert is usually injected into a vein (intravenously) by your doctor or nurse. You or your carer might also administer Berinert as an injection, but only after receiving adequate training. If your doctor decides that you may be suitable for such home-treatment, he/she will give you detailed instructions. You will be required to keep a diary in order to document each treatment received at home and to bring it to each of your visits to the doctor. Regular review of your/your carer’s injection technique will be performed to ensure continued appropriate handling.

General instructions

  • The powder must be dissolved and withdrawn from the vial under aseptic conditions. Use the syringe provided with the product.
  • The made-up Berinert 500 IU solution should be colourless and clear. Berinert 1500 IU may be colourless and clear to slightly opalescent. After filtering or withdrawal (see below) the solution should be checked by eye for small particles and discoloration, before it is administered.
  • Do not use the solution if it is visibly cloudy or if it contains flakes or particles.
  • Any unused product or waste material should be disposed of in accordance with local requirements and as instructed by your doctor.

Reconstitution

Without opening either vial, warm the Berinert powder and the solvent to room temperature. This can be done either by leaving the vials at room temperature for about an hour, or by holding them in your hands for a few minutes. DO NOT expose the vials to direct heat. The vials must not be heated above body temperature (37 °C).

Carefully remove the protective caps from the solvent vial and the product vial. Clean the exposed rubber stoppers of both vials with one alcohol swab each and allow them to dry. The solvent can now be transferred to the powder with the administration set (Mix2Vial) attached. Please follow the instructions given below.

1. Open the Mix2Vial package by peeling off the lid. Do not remove the Mix2Vial from the blister package!



  • 2. Place the solvent vial on an even, clean surface and hold the vial tight. Take the Mix2Vial together with the blister package and push the spike of the blue adapter end straight down through the solvent vial stopper.

  • 3. Carefully remove the blister package from the Mix2Vial set by holding at the rim, and pulling vertically upwards. Make sure that you only pull away the blister package and not the Mix2Vial set.


Place the product vial on an even and firm surface. Invert the solvent vial with the Mix2Vial set attached and push the spike of the transparent adapter end straight down through the product vial stopper. The solvent will automatically flow into the product vial.

  • 5. With one hand grasp the product-side of the Mix2Vial set and with the other hand, grasp the solvent-side and unscrew the set carefully into two pieces.

Discard the solvent vial with the blue Mix2Vial adapter attached.
