1. What is Besremi and what is it used for
Besremi contains the active substance ropeginterferon alfa-2b, which belongs to a class of medicines known as interferons. Your immune system produces interferons to block the growth of cancer cells.
Besremi is used as monotherapy for the treatment of polycythaemia vera in adults. Polycythaemia vera is a type of cancer in which the bone marrow produces too many red blood cells, white blood cells, and platelets (the cells that help the blood to clot).
2. What you need to know before you use Besremi
Do not useBesremi
- if you are allergic to ropeginterferon alfa-2b or any of the other ingredients of this medicine (listed in section 6).
- if you have an uncontrolled thyroid disease.
- if you have had severe mental health problems (such as depression or suicidal thoughts, or if you have attempted suicide).
- if you have had severe heart problems recently (such as a heart attack or stroke).
- if you have or have had an autoimmune disease (such as rheumatoid arthritis, psoriasis, or inflammatory bowel disease).
- if you have received an organ transplant and are taking medicines to suppress your immune system.
- if you are taking telbivudine (a medicine used to treat hepatitis B infection).
- if you have advanced and uncontrolled liver disease.
- if you have severe kidney disease (which makes your kidneys work less than 15% of normal).
Warnings and precautions
Talk to your doctor before you start using Besremi:
- if you have a thyroid disease.
- if you have diabetes or high blood pressure; your doctor may ask you to have an eye examination.
- if you have liver problems, you will have regular blood tests to check your liver function if you have been taking Besremi for a long time.
- if you have kidney problems.
- if you have psoriasis or other skin problems, as they may get worse during treatment with Besremi.
Once you have started treatment with Besremi, talk to your doctor:
- if you develop symptoms of depression (such as feeling sad, depressed, and having suicidal thoughts).
- if you develop signs of a severe allergic reaction (such as difficulty breathing, wheezing, or hives); in this case, you should seek medical help immediately.
- if you develop symptoms of a cold or other respiratory infection (such as difficulty breathing, cough, fever, and chest pain).
- if you have changes in your vision, you should consult your doctor, who will have your eyes examined immediately. Serious eye problems can occur during treatment with Besremi. Normally, your doctor will have your eyes examined before you start treatment. If you have health problems that can cause eye problems, such as diabetes or high blood pressure, your doctor will also have your eyes examined during treatment. If your vision gets worse, your doctor may decide to stop your treatment.
Medicines based on interferons can also cause dental and gum disorders, with the possibility of tooth loss. Additionally, dry mouth can be harmful to teeth or mouth mucosa during long-term treatment with Besremi. You should brush your teeth well twice a day and have regular dental check-ups.
It will take some time to reach your optimal individual dose of Besremi. Your doctor will decide if you need to be treated with another medicine to quickly reduce the number of cells in your blood, in order to prevent the formation of clots and bleeding.
Children and adolescents
Do not give this medicine to children or adolescents, as there is no information available on the use of Besremi in this age group.
Other medicines and Besremi
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
Do not use Besremi if you are taking telbivudine (for the treatment of hepatitis B), as the combination of these medicines increases the risk of developing peripheral neuropathy (numbness, tingling, or burning sensation in the arms and legs). Tell your doctor if you are receiving treatment with telbivudine.
Particularly tell your doctor if you are taking any of the following medicines:
- theophylline (a medicine used to treat respiratory diseases such as asthma)
- methadone (a medicine used to treat pain or opioid dependence)
- vortioxetine or risperidone (medicines used to treat mental disorders)
- cancer medicines such as those that stop or slow down the growth of blood cells in the bone marrow (e.g. hydroxyurea)
- medicines that act on the central nervous system to relieve pain, help you sleep, or calm you down (e.g. morphine, midazolam)
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Pregnancy
The effect of Besremi during pregnancy is unknown. The use of Besremi is not recommended during pregnancy. If you are able to become pregnant, your doctor will explain which effective contraceptive method you should use during your treatment with Besremi.
Breast-feeding

Driving and using machines
Do not drive or use machines if you feel dizzy, drowsy, or confused while using Besremi.
Besremi contains benzyl alcohol
This medicine contains 5 mg of benzyl alcohol per 0.5 ml. Benzyl alcohol may cause allergic reactions.
Talk to your doctor or pharmacist:
- if you are pregnant or breast-feeding.
- if you have liver or kidney disease,
This is because large amounts of benzyl alcohol can accumulate in the body and cause side effects (metabolic acidosis).
Besremi contains polysorbate 80
This medicine contains 0.025 mg of polysorbate 80 in each 0.5 ml. Polysorbates can cause allergic reactions. Tell your doctor if you have any known allergies.

3. How to use Besremi
Follow the instructions for administration of this medicine exactly as told by your doctor or pharmacist. If you are not sure, ask your doctor or pharmacist again.
Your doctor will determine the dose you need individually for your disease. The usual starting dose of Besremi is 100 micrograms every 2 weeks. After that, your doctor will gradually increase the dose and may change it during treatment. If you have severe kidney problems, the starting dose given by your doctor will be reduced to 50 micrograms.
This medicine is given by subcutaneous injection, which means it is injected into the tissue under the skin. It must not be injected into irritated skin, red skin, skin with bruises, infected skin, or skin with scars.
If you inject this medicine yourself, you will be taught how to prepare the medicine and inject it.
Never share the pre-filled pen Besremi with anyone, even if you change the needle, in order to avoid infectious diseases.
