Talk to your doctor, pharmacist or nurse before using IQYMUNE.
Certain adverse reactions may occur more frequently:
- in case of high rate of infusion.
- when you receive IQYMUNE for the first time or it is a long time since your last infusion. You will be watched carefully until an hour after the infusion to detect potential side effects.
In order to avoid a risk of a reaction the doctor will check the infusion rate and adjust it so it is suitable for you. During the infusion your doctor will put in place medical monitoring in order to detect any signs of allergy or any other reactions.
Allergic reactions are rare. If an allergy develops you will recognize the initial signs by dizziness, swelling of the face/legs, shortness of breath, spots on the skin and/or itching. Tell your doctor or healthcare professional immediately if you notice such reactions during or after the infusion of IQYMUNE.
Depending on your adverse reaction the doctor may decide to reduce the rate of your infusion or to stop it. He/she may also start treatment for the adverse event if he/she considers this to be necessary. If you have any doubt, please do not hesitate to ask your doctor or your nurse for advice.
Patients with pre-existing risk factors
This medicine may very rarely cause or worsen a kidney disease (acute kidney failure), a disease of the heart and/or a disease of the blood vessels (myocardial infarction, cerebrovascular accident (including stroke), pulmonary embolism or deep venous thrombosis). Patients who are already suffering from a disease or who have certain risk factors must take care when using this medicine.
Please inform your doctor of all medicines taken and diseases which you have or have had. Your doctor will take special care for you:
- if you already have a kidney disease (renal failure),
- if you are taking certain medicines which may be dangerous for your kidneys,
- if you have a high level of sugar in your blood (diabetes),
- if you have an insufficient volume of blood in your body (hypovolemia),
- if your weight is too high (obesity),
- if you are over 65 years old,
- if you already have a disease of the heart or blood vessels,
- if you have high blood pressure (arterial hypertension),
- if you are at risk of being immobilised for a long period of time,
- if you are suffering from a disease which causes an increase of your blood thickening (hyperviscous blood).
White blood cells
A transient decrease in the number of certain white blood cells (leukopenia/neutropenia) is common. Usually, it occurs within hours or days after the infusion and resolves spontaneously within 7 to 14 days.
Before using this medicine, you should tell the doctor when you know you have:
- a low number of white blood cells, or
- you take a medicine which could decrease the number of white blood cells.
Aseptic meningitis syndrome
Aseptic meningitis syndrome (reversible and non-infectious) has been reported to occur with immunoglobulin treatment such as IQYMUNE. The syndrome usually begins within several hours to 2 days following the treatment and may occur with the following symptoms: fever, headache, stiff neck, nausea, vomiting.
If you experience such symptoms, please check with your health care provider for a thorough neurological examination, to rule out other causes of meningitis.
Haemolytic anaemia/Haemolysis
Haemolytic anaemia (transient decrease of red blood cells, due to their destruction) can develop subsequently to immunoglobulin therapy such as IQYMUNE, particularly if you are of blood group A, B or AB. Reversible haemolytic anaemia may be characterized by the following symptoms: pallor, fatigue, weakness, yellowish skin or eyes, dark urine. If you receive immunoglobulins such as IQYMUNE, you should be monitored for clinical signs and symptoms of haemolysis.
Transfusion related acute lung injury (TRALI)
In patients receiving immunoglobulin such as IQYMUNE, there have been rare cases of Transfusion Related Acute Lung Injury (TRALI). This disease is characterized by decrease of oxygen level in the body (hypoxemia), difficulties in breathing (dyspnoea), increase of the respiratory rate (tachypnoea), blueing skin (cyanosis), fever and decrease of the blood pressure (hypotension). Symptoms of TRALI typically appear during the infusion of immunoglobulin or within 6 hours following the infusion, often within 1 to 2 hours. Therefore, if you notice any such reactions during IQYMUNE infusion, tell your doctor immediately. He/she will decide whether the infusion rate should be decreased or whether the infusion should be stopped.
Information on 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,
- the testing of each donation and pools of plasma for signs of virus/infections,
- the inclusion of 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 and other types of infections.
The measures taken are considered effective for viruses such as human immunodeficiency virus (HIV), hepatitis B virus, hepatitis C virus, hepatitis A virus and parvovirus B19.
Immunoglobulins have not been associated with hepatitis A or parvovirus B19 infections, possibly because antibodies against these infections, which are contained in the product, are protective.
It is strongly recommended that every time you are given a dose of IQYMUNE, the name and batch number of the product are recorded in order to maintain a record of the batches used.
