Dyrupeg contains the active substance pegfilgrastim. Pegfilgrastim is a protein produced by biotechnology in bacteria called E. coli. It belongs to a group of proteins called cytokines and is very similar to a natural protein (granulocyte-colony stimulating factor) produced by your own body.
Dyrupeg is used to reduce the duration of neutropenia (low white blood cell count) and the occurrence of febrile neutropenia (low white blood cell count with a fever), which can be caused by the use of cytotoxic chemotherapy (medicinal product that destroy rapidly growing cells), in adults aged 18 and over. White blood cells are important as they help your body fight infection. These cells are very sensitive to the effects of chemotherapy, which can cause the number of these cells in your body to decrease. If white blood cells fall to a low level, there may not be enough left in the body to fight bacteria, and you may have an increased risk of infection.
Your doctor has given you Dyrupeg to encourage your bone marrow (part of the bone that makes blood cells) to produce more white blood cells that help your body fight infection.
Talk to your doctor, pharmacist, or nurse before using Dyrupeg:
Your doctor will check your blood and urine regularly, as Dyrupeg can harm the tiny filters inside your kidneys (glomerulonephritis).
Severe skin reactions (Stevens-Johnson syndrome) have been reported with the use of pegfilgrastim. Stop using Dyrupeg and seek medical attention immediately if you notice any of the symptoms described in section 4.
You should talk to your doctor about your risks of developing cancers of the blood. If you develop or are likely to develop cancers of the blood, you should not use Dyrupeg unless instructed by your doctor.
If you experience a loss of response or failure to maintain a response with pegfilgrastim treatment, your doctor will investigate the reasons why, including whether you have developed antibodies that neutralize pegfilgrastim’s activity.
Dyrupeg is not recommended for use in children and adolescents due to insufficient data on safety and effectiveness.
