What it is and what it is used for

for

What is Berinert? Berinert is presented as powder and solvent. The made-up solution is to be given by injection under the skin. Berinert is made from human plasma (this is the liquid part of the blood). It contains the protein human C1-esterase inhibitor as active ingredient. What is Berinert used for? Berinert is used for the prevention of recurrent hereditary angioedema (HAE) attacks in adolescent and adult patients. HAE is a congenital disease of the vascular system. It is a nonallergic 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.

What you need to know before you take it

e Berinert

The following sections contain information that your doctor should consider before you are given Berinert. Do not use Berinert:  if you have experienced life-threatening immediate hypersensitivity reactions, including anaphylaxis, 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. Warnings and precautions: Talk to your doctor or pharmacist before using Berinert,  if severe allergic or anaphylactic-type reactions occur (a serious allergic reaction that causes severe difficulty in breathing or dizziness). Administration of Berinert should be stopped immediately (e.g. discontinue injection).  if you have a history of blood clotting problems. Blood clots have occurred in patients receiving intravenous Berinert. Very high doses of Berinert in diseases other than HAE, could increase the risk of blood clots. However, for subcutaneous Berinert, there is no established link with blood clots at the dose that your doctor is recommended to prescribe. Tell your doctor if you have a history of heart or blood vessel disease, stroke, blood clots or have thick blood, an indwelling catheter/access device in one of your veins, or have been immobile for some time. These things may increase your risk of having a blood clot after using Berinert. Also tell your doctor what drugs you are using, as some drugs, such a birth control pills or certain androgens, may increase your risk of developing a blood clot. 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  Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.  Berinert should not be mixed with other medicinal products and diluents in the syringe. Pregnancy and breast-feeding 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. Driving and using machines Berinert does not affect your ability to drive and use machines. Berinert contains sodium Berinert 2000 IU contains less than 1 mmol sodium (23mg) per vial, that is to say essentially 'sodium-free'. Berinert 3000 IU contains up to 29 mg sodium (main component of cooking/table salt) in each vial. This is equivalent to 1.5% of the recommended maximum daily dietary intake of sodium for an adult. 3.

How to take it

Berinert

Berinert is intended for self-administration by subcutaneous injection. You or your carer has to be trained on how to administer Berinert as needed. Dosage The recommended dose of Berinert is 60 IU/kg body weight. Paediatric population The recommended dose is the same as in adults. Overdose No case of overdose has been reported. Reconstitution and method of administration If your doctor decides that you may be suitable for 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 solution should 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! 1 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. 2 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. 3 4. 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. 4 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 counterclockwise into two pieces. Discard the solvent vial with the blue Mix2Vial adapter attached. 5 6. Gently swirl the product vial with the transparent adapter attached until the substance is fully dissolved. Do not shake. 6

7. Draw air into an empty, sterile syringe. Use the syringe provided with the product. While the product vial is upright, connect the syringe to the Mix2Vial's Luer Lock fitting by screwing clockwise. Inject air into the product vial.

7 Withdrawal and application 8. While keeping the syringe plunger pressed, invert the system upside down and draw the solution into the syringe by pulling the plunger back slowly.

8 9. Now that the solution has been transferred into the syringe, firmly hold on to the barrel of the syringe (keeping the syringe plunger facing down) and disconnect the transparent Mix2Vial adapter from the syringe by unscrewing counterclockwise.
