1. What is Stimufend and what is it used for
Stimufend contains the active substance pegfilgrastim. Pegfilgrastim is a protein produced by biotechnology in the bacterium E. coli. Pegfilgrastim belongs to a group of proteins called cytokines and is very similar to a natural protein (granulocyte-colony stimulating factor) produced by the body.
Stimufend is used to reduce the duration of neutropenia (low white blood cell count) and the incidence of febrile neutropenia (low white blood cell count and fever) that can occur as a result of cytotoxic chemotherapy (medicines that destroy rapidly dividing cells). White blood cells are important cells that help fight infections. These cells are sensitive to the effects of chemotherapy, which can cause their numbers to decrease. If the number of white blood cells becomes too low, there may not be enough to fight off bacteria, which can lead to an increased risk of infection.
Your doctor has prescribed Stimufend to stimulate your bone marrow (the part of the bone where blood cells are produced) to produce more white blood cells to help fight infections.
2. What you need to know before you use Stimufend
Do not use Stimufend
- if you are allergic to pegfilgrastim, filgrastim, or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before starting Stimufend:
- if you experience an allergic reaction that includes weakness, low blood pressure, difficulty breathing, swelling of the face (anaphylaxis), redness and flushing, skin rash, and itching.
- if you are allergic to latex. The needle cap of the pre-filled syringe contains a latex derivative and may cause severe allergic reactions.
- if you are allergic to acrylic adhesives. The on-body injector uses an acrylic adhesive that may cause allergic reactions.
- if you experience cough, fever, and difficulty breathing. This may be a sign of Acute Respiratory Distress Syndrome (ARDS).
- if you experience any of the following side effects:
- swelling that may be associated with decreased urine output, difficulty breathing, swelling, and a feeling of fullness in the abdomen, and a general feeling of tiredness.
These may be symptoms of a rare condition called "Capillary Leak Syndrome" and may cause blood to leak from small blood vessels into other parts of the body. See section 4.
- if you have pain in the upper left abdomen or pain in the tip of the shoulder. This may be a sign of a problem with the spleen (splenomegaly).
- if you have recently had a severe lung infection (pneumonia), fluid in the lungs (pulmonary edema), inflammation of the lungs (interstitial lung disease), or an abnormal chest X-ray (pulmonary infiltrate).
- if you are aware of any changes in your blood cell count (e.g., increased white blood cell count or anemia) or a decrease in platelet count, which can reduce the ability of the blood to clot (thrombocytopenia). Your doctor may want to monitor you more closely.
- if you have sickle cell anemia. Your doctor may monitor your condition more closely.
- if you are a cancer patient, the combined treatment of Stimufend with chemotherapy and/or radiotherapy may increase the risk of developing a pre-cancerous blood disorder called myelodysplastic syndrome (MDS) or a blood cancer called acute myeloid leukemia (AML). Symptoms may include tiredness, fever, easy bruising or bleeding.
- if you experience sudden signs of allergy, such as rash, itching, or hives on the skin, swelling of the face, lips, tongue, or other parts of the body, shortness of breath, wheezing, or difficulty breathing, these may be signs of a severe allergic reaction.
- if you experience symptoms of inflammation of the aorta (the large blood vessel that carries blood from the heart to the rest of the body), this has rarely been reported in cancer patients and healthy donors. Symptoms may include fever, abdominal pain, general malaise, back pain, and increased inflammatory markers. Inform your doctor if you experience these symptoms.
Your doctor will regularly perform blood and urine tests as Stimufend may damage the small filters inside the kidneys (glomerulonephritis).
With the use of pegfilgrastim, severe skin reactions (Stevens-Johnson syndrome) have been reported. Stop using pegfilgrastim and seek medical attention immediately if you notice any of the symptoms described in section 4.
You should discuss with your doctor the risk of developing blood cancer. If you develop or may develop blood cancer, you should not use Stimufend, unless your doctor advises you to.
Loss of response to pegfilgrastim
If you experience a loss of response or if the response to treatment with pegfilgrastim cannot be maintained, your doctor will investigate the causes, including whether you have developed antibodies that may neutralize the activity of pegfilgrastim.
Other medicines and Stimufend
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
