BESREMI 250 MG / 0.5ML SOLUTION FOR INJECTION IN PRE-FILLED PEN - patient leaflet, side effects, dosage

1. what besremi is and what it is used for

Besremi contains the active substance ropeginterferon alfa-2b, which belongs to the class of medicinal products called interferons. Interferons are produced by your immune system 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 (cells that help the blood to clot).

2. what you need to know before you use besremi

Do not use Besremi:

• – if you are allergic to ropeginterferon alfa-2b or any of the other ingredients of this medicine (listed in section 6).

• – if you have thyroid disease that is not controlled with medicines.

• – if you have or had severe mental disorders (such as depression or suicidal thoughts or if you tried to kill yourself).

• – if you have recently had severe heart problems (such as heart attack or stroke).

• – if you have psoriasis or other skin problems because they may get worse during treatment with Besremi.

Once you have started Besremi treatment, talk to your doctor:

• – if you develop symptoms of depression (such as feelings of sadness, dejection, and suicidal thoughts).

• – if you develop signs of a severe allergic reaction (such as difficulty in breathing, wheezing or hives) while using Besremi – if this is the case you will need to seek medical help immediately.

Your doctor will usually check your vision before starting your treatment. If you have health problems which may lead to eye problems such as diabetes or high blood pressure, you doctor should check your vision also during treatment. If your vision worsens, your doctor may decide to discontinue your treatment.

Dental and gum disorders, which may lead to loss of teeth, can occur with interferon medicines. In addition, dry mouth could damage teeth and the lining of the mouth during long-term treatment with Besremi. You should brush your teeth thoroughly twice daily and have regular dental checks.

It will need a certain time to reach your individual optimal dose of Besremi. Your doctor will decide if it is necessary to treat you with another medicine for an early reduction of your blood cell number to prevent blood clots and bleeding.

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 treating hepatitis B) since the combination of these medicines increases the risk of peripheral neuropathy (numbness, tingling, or burning sensations in the arms and legs). Tell your doctor if you are being treated with telbivudine.

• – 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)

• – anti-cancer medicines such as those stopping or slowing the growth of blood-forming cells in the bone marrow (e.g. hydroxycarbamide)

• – medicines that work on the central nervous system to relieve pain, help you sleep, or have a calming effect (e.g. morphine, midazolam)
