1. What Fendrix is and what it is used for

Fendrix is a vaccine that prevents hepatitis B.

It is used in patients with kidney problems:

  • patients undergoing haemodialysis, where a dialysis machine removes waste products from the blood
  • patients who will undergo haemodialysis in the future.

Fendrix is for adults and adolescents from 15 years of age.

What is hepatitis B

Hepatitis B is caused by a virus that makes the liver swell.

  • Signs may not be noticed until 6 weeks to 6 months after infection.
  • The main signs of the disease include mild flu-like signs such as headache or fever, extreme tiredness, dark urine, pale stools, or yellowing of the eyes or skin (jaundice). These or other signs may mean that the person needs hospital treatment. Most people recover completely from the disease.
  • Some people with hepatitis B may not seem or feel ill (they have no signs of the disease).
  • The virus is found in body fluids such as in the vagina, blood, semen or saliva (sputum).

Hepatitis B carriers

  • The hepatitis B virus stays in some people's bodies for their whole lives.
  • This means they can infect others and are known as virus carriers.
  • Carriers of the virus are likely to develop serious liver problems, such as cirrhosis or liver cancer.

How Fendrix works

  • Fendrix helps your body to develop its own protection against the virus (antibodies). These antibodies will protect you against the disease.
  • Fendrix contains two substances called MPL (a purified non-toxic bacterial derivative) and aluminium phosphate. Both help the vaccine to work faster, better and for longer.
  • As with all vaccines, a course of vaccination with Fendrix may not fully protect all people who are vaccinated.
  • Fendrix may not protect you against the disease if you have already been infected with the hepatitis B virus.
  • Fendrix can only protect you against infection with the hepatitis B virus. It cannot protect you against other infections that may affect the liver, even if these infections have similar signs to those caused by the hepatitis B virus.
Doctor consultation

Discuss your symptoms and treatment with a doctor online.

2. What you need to know before you receive Fendrix

Fendrix must not be administered

  • if you are allergic to the active substance or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction may include: itchy skin rash, difficulty breathing, swelling of the face or tongue
  • if you have ever had an allergic reaction to any hepatitis B vaccine
  • if you have a severe infection with fever. The vaccine can be given once you have recovered. A minor infection such as a cold should not be a problem for vaccination, but tell your doctor first.

Fendrix must not be administered if any of the above applies to you. If you are not sure, consult your doctor or pharmacist before receiving Fendrix.

Warnings and precautions

Consult your doctor or pharmacist before Fendrix is administered to you:

  • if you have known allergies
  • if you have had any health problems after receiving a vaccine in the past.

Fainting (especially in adolescents) may occur before or after any injection, so you should tell your doctor or nurse if you have fainted after a previous injection.

If any of the above applies to you (or if you are not sure), consult your doctor or pharmacist before receiving Fendrix.

Other medicines and Fendrix

Tell your doctor if you are using, have recently used or might use any other medicines or if you have recently received any other vaccine.

  • You should have a gap of at least 2 to 3 weeks between administration of Fendrix and any other vaccine.
  • Fendrix may need to be given at the same time as an injection of hepatitis B immunoglobulin. Your doctor will make sure that the vaccines are given in different parts of your body.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before receiving this vaccine.

Driving and using machines

You may feel tired or have a headache after receiving Fendrix. If this happens, be extra careful while driving or using tools or machines.

Fendrix contains sodium

This vaccine contains less than 1 mmol of sodium (23 mg) per dose, i.e. it is essentially “sodium-free”.

3. How Fendrix is administered

How the vaccine is administered

The doctor or nurse will inject Fendrix into a muscle, usually in the upper part of your arm.

How much is administered

  • You will receive a series of four injections.
  • The injections will be given over a period of 6 months:
  • First injection: on the date agreed with your doctor.
  • Second injection: 1 month after the first injection
  • Third injection: 2 months after the first injection.
  • Fourth injection: 6 months after the first injection.
  • The doctor or nurse will tell you when to come back for the next injections.
  • Once you have received the first injection of Fendrix, it is necessary that the next injections are also of Fendrix (not another type of hepatitis B vaccine).

Your doctor will tell you if you need any additional injections or booster doses in the future. Fendrix can also be used as a booster dose after a course of vaccination with a different type of hepatitis B vaccine.

If you miss a dose

  • If you miss an injection, contact your doctor and make another appointment.
  • Make sure you complete the full course of four injections. Otherwise, you may not be fully protected against the disease.

-------------------------------------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

During storage of the vaccine, a fine white deposit and a clear supernatant may be observed.

Before administration, the vaccine should be shaken well to obtain a slightly opaque white suspension.

The vaccine should be inspected visually before and after resuspension for any foreign particles and/or changes in physical appearance. The vaccine should not be used if there has been a change in the appearance of the vaccine.

Disposal of unused medicinal products and all materials that have come into contact with them should be carried out in accordance with local regulations.

Fendrix should not be administered to subjects with hypersensitivity to the active substance or to any of the excipients.

Fendrix should not be administered to subjects with hypersensitivity after a previous administration of other hepatitis B vaccines.

Fendrix should not be administered to subjects with acute severe febrile illnesses. The presence of a minor infection, such as a cold, is not a contraindication for vaccination.

Fendrix should be injected intramuscularly into the deltoid region.

Intramuscular administration into the gluteal muscle should be avoided as it may lead to a suboptimal immune response to the vaccine.

Fendrix should not be administered intradermally or intravenously under any circumstances.

Due to the fact that pre-dialysis and dialysis patients are particularly exposed to HBV and have a higher risk of being chronically infected, a preventive attitude should be considered, i.e., a booster dose should be administered to ensure a protective level of antibodies based on local recommendations and guidelines.

Adequate medical treatment should be available at all times in the event of an anaphylactic reaction following administration of the vaccine.
