1. What Rhophylac 300 is and what it is used for
What Rhophylac 300 is
This medicine is a ready-to-use solution for injection, which comes in a pre-filled syringe. The solution contains special proteins, isolated from human plasma. These proteins belong to a class called "immunoglobulins", also known as antibodies. The active substance of Rhophylac 300 is a specific antibody called "anti-D (Rh) immunoglobulin". This antibody acts against the Rhesus D factor.
What the Rhesus D factor is
Rhesus factors are special characteristics of human red blood cells. About 85% of the population has the so-called Rhesus D factor (abbreviated "Rh(D)"). These people are called Rh(D) positive. People who do not have the Rhesus D factor are called Rh(D) negative.
What anti-D (Rh) immunoglobulin is
Anti-D (Rh) immunoglobulin is an antibody that acts against the Rhesus D factor and is produced by the human immune system. When an Rh(D) negative person receives Rh(D) positive blood, their immune system recognizes the Rh(D) positive red blood cells as "foreign" to their body and tries to destroy them. To do this, the immune system produces a specific antibody against the Rhesus D factor. This process is called "immunization" and usually takes some time (2-3 weeks). Therefore, the Rh(D) positive red blood cells will not be destroyed after the first contact, and no signs or symptoms are normally seen. But when the same Rh(D) negative person receives Rh(D) positive blood a second time, the antibodies will be "available" and their immune system will destroy the foreign red blood cells immediately.
How Rhophylac 300 works
If an Rh(D) negative person receives a sufficient dose of human anti-D (Rh) immunoglobulin, immunization against the Rhesus D factor can be prevented. To achieve this, treatment with Rhophylac 300 must start before or as soon as possible after the first contact with Rh(D) positive red blood cells. The anti-D (Rh) immunoglobulin contained in this medicine will destroy the foreign Rh(D) positive red blood cells immediately. Thus, the person's immune system will not produce its own antibodies.
What Rhophylac 300 is used for
This medicine is used in two different situations:
- If you are an Rh(D) negative woman, pregnant with an Rh(D) positive baby
In this special situation, you may be immunized by the Rh(D) positive red blood cells of your baby that have passed into your bloodstream. If this happens, your first baby will usually not be affected and will be completely healthy. However, in your next Rh(D) positive baby, your maternal antibodies will destroy the Rh(D) positive red blood cells of the baby during pregnancy. This can cause complications in the development of your next baby, including possible death.
For this reason, you must receive Rhophylac 300:
? when you are pregnant with, or have just given birth to, an Rh(D) positive baby;
? when you have lost an Rh(D) positive baby (fetal death, abortion, or threatened abortion);
? when your pregnancy is complicated (ectopic pregnancy or pregnancy with a non-viable fertilized egg (molar pregnancy));
? when it is likely that your baby's Rh(D) positive red blood cells have passed into your bloodstream (transplacental hemorrhageas a result of antepartum hemorrhage). This can happen, for example, when you experience vaginal bleeding during pregnancy.
? when your doctor needs to perform tests to detect fetal malformations (amniocentesis, chorionic villus sampling, cordocentesis);
? when your doctor or midwife needs to try to manipulate your baby from the outside (e.g., external version of the baby or other obstetric manipulations);
? when you suffer an accident that damages your stomach or abdomen (abdominal trauma).
This medicine is also used if you are an Rh(D) negative woman who is pregnant and it is not known if your baby is Rh(D) positive.
(B) You are an adult, child, or adolescent (0-18 years) who is Rh(D) negative and has accidentally received Rh(D) positive blood transfusions or other preparations that contain Rh(D) positive red blood cells, such as "platelet concentrate" (wrong transfusion).
2. What you need to know before you use Rhophylac 300
?Read this section carefully. The information contained must be taken into account by both you and your doctor before you are given this medicine.
Do not use Rhophylac 300:
- If you are allergic (hypersensitive) to human immunoglobulins or to any of the other components of this medicine (listed in section 6).
- Please inform your doctor, pharmacist, or nurse before treatment about any medicine that you have not tolerated well in the past.
- You should not receive intramuscular injections if you have a severe reduction in the number of platelets (thrombocytopenia) or any other coagulation disorder.
- Please inform your doctor, pharmacist, or nurse before treatment if this applies to you. In this case, this medicine may only be administered to you as an intravenous injection.
Warnings and precautions
? Consult your doctor or nurse before starting treatment with Rhophylac 300.
- To protect Rh(D) negative women after giving birth to an Rh(D) positive baby, this medicine must always be administered to the mother, not the newborn.
- This medicine is not indicated in Rh(D) positive individuals or in individuals who have been immunized against the Rh(D) antigen.
When stopping treatment may be necessary
- Rhophylac 300 may cause hypersensitivity reactions (allergic reactions). In rare cases, allergic reactions such as a sudden drop in blood pressure or shock (see also section "4. Possible side effects") may occur, even if you have previously received human immunoglobulins and tolerated them well.
? Please inform your doctor or nurse immediately if these reactions occur. They will stop the administration of the product and start the appropriate treatment, depending on the nature and severity of the side effect.
Your doctor or nurse will be particularly careful
? If you have low levels of IgA immunoglobulins, you have a higher risk of presenting hypersensitivity reactions.
? Please inform your doctor or nurse if you have low levels of IgA immunoglobulins. They will carefully weigh the benefits of treatment with this medicine against the increased risk of hypersensitivity reactions.
- If you are being treated with this medicine after receiving an incompatible transfusion, you may be given a large amount of the product (up to 3,000 micrograms, equivalent to 20 ml or 10 syringes). In this case, a so-called hemolytic reaction may occur. This is a consequence of the destruction of the foreign Rh(D) positive red blood cells in your body. For this reason, your doctor or healthcare professional will closely monitor you and may need to perform special blood tests.
- If your body mass index (BMI) is 30 or higher (calculated by dividing your body weight by the square of your height), intramuscular injection of Rhophylac may not be fully effective. In this case, your doctor or nurse should inject this medicine into a vein.
Safety information regarding infections
This medicine is obtained from human plasma (which is the liquid part of the blood).
When medicines are manufactured from human blood or plasma, certain measures are taken to prevent infections from being passed on to patients. These include:
- careful selection of blood and plasma donors to ensure that those who may be at risk of transmitting infections are excluded,
- testing of each donation and plasma pool for signs of virus/infection.
- inclusion of steps in the processing of blood or plasma that can inactivate or remove viruses.
Despite these measures, when medicines obtained from human blood or plasma are administered, the possibility of transmitting infectious agents cannot be totally excluded. This also applies to any unknown or emerging virus or other types of infection.
The measures taken are considered effective against enveloped viruses such as human immunodeficiency virus (HIV, the AIDS virus), hepatitis B virus, and hepatitis C virus.
The measures may have limited value against non-enveloped viruses such as hepatitis A virus and parvovirus B19.
Immunoglobulins have not been associated with hepatitis A or parvovirus B19 infections, possibly because the antibodies against these infections present in the product are protective.
It is strongly recommended that each time you receive a dose of Rhophylac 300, the name and batch number of the product should be recorded to maintain a record of the batches used.
Blood tests
? Inform your doctor or nurse that you have been treated with Rhophylac 300 if you are going to have a blood test (serological test) or if your newborn is going to have a blood test.
After administration of this medicine, the results of certain blood tests may be altered for some time. If you are a mother who was given this medicine before birth, the results of certain blood tests in your newborn may also be affected.
Using Rhophylac with other medicines
? Inform your doctor or pharmacist if you are using, have recently used, or might use any other medicines, including those obtained without a prescription.
Vaccinations
? If you have been vaccinated in the last 2-4 weeks, please inform your doctor or nurse before treatment.
Also, inform the doctor who administers the vaccines after treatment. This way, they can check the effectiveness of your vaccination.
This medicine may interfere with the effectiveness of live virus vaccines, such as measles, mumps, rubella, or chickenpox. Therefore, such vaccines should not be given until 3 months after the last administration of Rhophylac 300.
Pregnancy and breastfeeding
This medicine is used during pregnancy or shortly after birth.
Immunoglobulins are excreted in breast milk. In clinical studies where 432 mothers received this medicine before birth and 256 of them again after birth, no adverse effects were detected in their babies.
Driving and using machines
No effects of Rhophylac 300 on the ability to drive or use machines are expected.
Rhophylac contains sodium
This medicine contains less than 1 mmol (23 mg) of sodium per syringe; this is, essentially "sodium-free".
