Uses for alectinib
Alectinib is used to treat metastatic (cancer that has already spread) non-small cell lung cancer in patients who have an abnormal anaplastic lymphoma kinase (ALK) gene. It is used in patients who have already received other medicines that did not work well. Your doctor will use a special test to look for this mutation.
Alectinib interferes with the growth of cancer cells which are then destroyed by the body. It is an antineoplastic agent (cancer medicine).
Alectinib is available only with your doctor's prescription.
