1. What is Human Hemin Orphan Europe and what is it used for

Human Hemin Orphan Europe contains human hemin, a substance derived from human blood.
Human Hemin Orphan Europe is used to treat acute attacks in patients suffering from acute hepatic porphyria. This disease is characterized by the accumulation of certain chemical compounds in the liver (including porphyrins and their toxic precursors). There are three types of hepatic porphyria with the following medical names: acute intermittent porphyria, variegate porphyria, and hereditary coproporphyria.
The accumulation of substances leads to the occurrence of disease symptoms, including pain (mainly abdominal, back, and limb), nausea, vomiting, and constipation.

2. Important information before using Human Hemin Orphan Europe

When not to use Human Hemin Orphan Europe

Warnings and precautions

• Before starting treatment with Human Hemin Orphan Europe, the doctor should confirm the diagnosis of acute hepatic porphyria based on a series of clinical and biological criteria: significant family and medical history; clear clinical symptoms; quantitative determination of delta-aminolevulinic acid and porphobilinogen (i.e., specific disease markers) in urine
• The sooner the treatment with Human Hemin Orphan Europe is started after the onset of the attack, the more effective the treatment will be.

As a result of administering Human Hemin Orphan Europe by infusion, abdominal pain and other gastrointestinal symptoms usually disappear within 2-4 days. The treatment has a smaller effect on neurological complications (paralysis and mental disorders).
During the full treatment cycle, the doctor will monitor the patient's condition, as acute porphyria attacks are often accompanied by various effects on the heart and circulatory system, as well as the nervous system.

• Do not:
• make sudden changes to your daily diet, in particular, do not make long breaks in eating;
• take medications or substances such as estrogens (e.g., oral contraceptives), barbiturates (sleeping pills, also used to treat epilepsy), or steroids (derivatives of natural hormones); their use may cause an attack or worsen its course. Always consult a doctor or pharmacist for advice on medications and substances that should not be used (now and in the future).
• To prevent vein irritation, the solution should be administered into large veins in the arm or chest for at least 30 minutes. After the infusion, the vein should be flushed with a physiological saline solution.

Blood clots (a condition called venous thrombosis) can block the vein into which the medicine was administered by infusion.

• If the intravenous cannula is left in the vein for too long, it may cause vessel damage, which can lead to unintended leakage of Human Hemin Orphan Europe outside the vein (extravasation). This leakage can cause skin discoloration.

To minimize the risk of extravasation, the nurse/doctor will check the cannula before infusion and will regularly check it during infusion.
The solution administered by infusion may give the patient's blood a different color.
To limit the risk of iron accumulation, Human Hemin Orphan Europe should not be used as a preventive treatment for acute attacks.
Human hemin contains iron. It may happen that after several years of treatment involving repeated administration of Human Hemin Orphan Europe by infusion, iron will accumulate in the body.
The doctor may from time to time perform blood tests to check the iron content in the patient's body.

• Standard measures to protect against infections resulting from the use of products derived from human blood or plasma involve proper selection of donors, testing each donated unit for specific infection markers, and strict adherence to the manufacturing process stages aimed at inactivating or removing viruses. Despite this, the risk of transmitting infectious agents cannot be excluded if the medicines are prepared from plasma and human blood. This also applies to unknown or newly emerging viruses and other pathogens.
• The methods used are considered effective for enveloped viruses, such as HIV, HBV, and HCV. It is necessary to record the name and batch number of the Human Hemin Orphan Europe preparation each time it is administered to the patient, in order to identify the preparation administered later.

Human Hemin Orphan Europe and other medicines
