Like all medicines, Temozolomide Hospira can cause side effects, although not everybody gets them.
Patients taking temozolomide in combination with radiation therapy may experience different side effects than patients taking temozolomide alone.
Contact your doctor immediately if you have a severe allergic reaction (rash which might be itchy, wheezing or other breathing difficulty), uncontrolled fits, fever or a severe headache that does not go away.
Temozolomide treatment can cause a reduction in certain kinds of blood cells. This may cause you to have increased bruising or bleeding, anaemia, fever, and/or a reduced resistance to infections. The reduction of blood cells is usually temporary, but in some cases may be for longer and may lead to a very severe form of anaemia (aplastic anaemia). Your doctor will monitor your blood regularly for any changes, and will decide if any specific treatment is needed. In some cases, your temozolomide dose will be reduced or discontinued.
The following side effects may occur if you are a newly diagnosed patient taking Temozolomide Hospira for a specific brain tumour (glioblastoma multiforme) in combination treatment with radiotherapy and then later taking temozolomide on its own. Medical attention may be required.
