Ribociclib (Kisqali)

Why is Ribociclib prescribed?

Ribociclib (Kisqali) is used in combination with another medication to treat a certain type of hormone receptor-positive (depends on hormones such as estrogen to grow) advanced breast cancer or that has spread to other parts of the body in women who have not experienced menopause (change of life; end of monthly menstrual periods) and in those who are close to or who have already experienced menopause.

It is also used in combination with fulvestrant (Faslodex) to treat a certain type of hormone-receptor-positive advanced breast cancer or that has spread to other parts of the body as an initial treatment or in people who have not been treated successfully with other treatments in women who have already experienced menopause.

Ribociclib (Kisqali) is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.

Storage and disposal of Ribociclib

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
