Uses For Kisqali
Ribociclib is used in combination with letrozole in patients (women before or after menopause) with hormone receptor (HR)-positive, HER-2 negative advanced or metastatic breast cancer. It is also used together with fulvestrant (postmenopausal women) to treat HR-positive, HER-2 negative advanced or metastatic breast cancer. It belongs to the group of medicines called antineoplastics.
Ribociclib interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal cells may also be affected by the medicine, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor.
