Contents of thepackage leaflet
Factor IX Grifols is a medicine that contains human coagulation factor IX.
Factor IX Grifols belongs to a group of medicines called antihemorrhagics: blood coagulation factors.
Factor IX Grifols is indicated for the treatment and prophylaxis (prevention) of bleeding in patients with hemophilia B (congenital factor IX deficiency). These patients do not have enough functional factor IX. Factor IX Grifols is used to increase the amount of factor IX in the blood, allowing it to clot.
Do not useFactor IX Grifols
If you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6). See important information about some of the ingredients of Factor IX Grifols at the end of this section.
If you have any doubts about the above, consult your doctor.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to use Factor IX Grifols.
When medicines are prepared from human blood or plasma, a number of measures must be taken to prevent the possible transmission of infections to patients. These measures include:
Despite these measures, when medicines prepared from human blood or plasma are administered, the possibility of transmission of infections cannot be completely excluded. This also applies to unknown or emerging viruses and other types of infections.
The measures taken are considered effective for enveloped viruses such as human immunodeficiency virus (HIV), hepatitis B virus, and hepatitis C virus, and for the non-enveloped hepatitis A virus. The measures taken may have limited value for non-enveloped viruses such as parvovirus B19.
Parvovirus B19 infection can be severe for a pregnant woman (fetal infection) and for people whose immune system is depressed or who have some type of anemia (e.g., with sickle cell anemia or hemolytic anemia).
Your doctor may recommend that you consider vaccination against hepatitis A and B if you regularly receive human plasma-derived factor IX concentrates.
Each time you are administered a dose of Factor IX Grifols, it is recommended to keep a record of the name and batch number of the medicine to maintain a record of the batches used.
There may be a possible connection between the development of factor IX inhibitors and allergic reactions. Patients with factor IX inhibitors may have a higher risk of anaphylactic reactions. Therefore, in patients who suffer an allergic reaction, the presence of a factor IX inhibitor should be investigated.
Using Factor IX Grifols with other medicines
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Driving and using machines
There is no indication that Factor IX Grifols may affect the ability to drive or use machines.
Sodium content
Factor IX Grifols contains 20.7 mg of sodium in the 250 UI/5 ml presentation, 41.4 mg of sodium in the 500 UI/10 ml presentation, 82.8 mg of sodium in the 1000 UI/20 ml presentation, and 124.2 mg of sodium in the 1500 UI/30 ml presentation. This is equivalent to 1.04%, 2.07%, 4.14%, and 6.21%, respectively, of the maximum daily sodium intake recommended by the WHO for an adult (2 g of sodium).
Reconstitute the product as described in this section. The product should be administered slowly, especially the first dose (approximately 3 ml/min) by intravenous route.
Follow exactly the administration instructions of this medicine indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.
Your doctor will decide the dose of Factor IX Grifols you will receive. This dose and its duration will depend on your individual needs for factor IX replacement therapy and pharmacokinetics (recovery and half-life), which should be regularly checked.
Your doctor may modify the dose of Factor IX Grifols you receive over time.
Dose for treatment
The required dose is determined using the following formula:
Required units = body weight (kg) x desired increase in factor IX (%) (UI/dl) x 0.8
Dose for prophylaxis in bleeding
In routine prophylaxis to prevent bleeding in patients with severe hemophilia B, doses of 20 to 40 UI of factor IX/kg of body weight should be administered at intervals of 3 to 4 days. In some cases, especially in young patients, it may be necessary to shorten the administration intervals or use higher doses.
Patients with inhibitors
If you have developed factor IX inhibitors, you may need a higher amount of Factor IX Grifols to control bleeding. If this dose does not control bleeding, your doctor may consider the use of an alternative medicine. Do not increase the total dose of Factor IX Grifols you use to control your bleeding without consulting your doctor.
Instructions for use/handling
Follow these instructions unless your doctor has given you different instructions.

No cases of overdose with human coagulation factor IX have been reported. However, if you have used Factor IX Grifols more than you should, consult your doctor or pharmacist immediately.
In case of overdose or accidental administration, consult the Toxicological Information Service, phone 91 562 04 20.
If you forget to use Factor IX Grifols
Like all medicines, this medicine can cause side effects, although not everybody gets them.
In rare cases, you may notice one of the following side effects after administration of Factor IX Grifols:
It cannot be completely excluded that an anaphylactic shock may occur. If you notice any of the following symptoms during injection/infusion
it may be an early sign of hypersensitivity and anaphylactic reaction. If an allergic reaction or anaphylaxis occurs, the injection/infusion must be interrupted and your doctor consulted immediately.
However, it cannot be completely excluded that there is a possibility of allergic reactions to the components of the preparation. The formation of neutralizing antibodies against factor IX (inhibitors) is a known complication in the treatment of patients with hemophilia B. The development of inhibitors should be carefully monitored by laboratory tests and appropriate clinical examinations to determine the formation of such inhibitors.
There is a risk of thromboembolic complications with Factor IX Grifols, particularly if you have a risk of thrombosis and/or receive high-dose therapy.
