Ribociclib
About Ribociclib
Ribociclib is a prescription medicine used to treat hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer. It is prescribed in combination with hormone therapies to help slow the spread of cancer cells throughout the body. Your doctor will determine if your specific cancer type is suitable for this treatment.
This medicine is typically taken once daily at the same time each day, following a specific cycle of consecutive treatment days followed by a rest period. You can take this medication with or without food, but it is important to swallow the tablets whole. Making mindful lifestyle choices, such as eating a balanced diet and staying well-hydrated, can help support your body during this treatment cycle.
While taking Ribociclib, you may experience common side effects like tiredness, nausea, and a decrease in infection-fighting white blood cells. It is vital to contact your doctor immediately if you develop any signs of infection, such as a fever, or if you experience severe shortness of breath or yellowing of your eyes or skin.
Before you begin taking this medicine, tell your doctor about your complete medical history, especially if you have heart, kidney, or liver conditions. Do not take this if you are allergic to Ribociclib or any of the inactive ingredients contained in the tablet.
This medicine can interact with certain other prescription drugs, herbal supplements, and grapefruit products, which may alter how the medication works in your body. If you are pregnant, planning to become pregnant, or breastfeeding, you should not take this medicine because it can cause serious harm to a developing baby.
Uses of Ribociclib

Patients Concern
Disease/Condition Glossary
Breast cancer: It is a type of cancer that develops in the breast when the breast cells begin to grow abnormally. Breast cancer may form in lobules (glands that produce milk), ducts of the breast (the pathway that brings milk from glands to the nipple), in the fatty tissue or the fibrous connective tissue within the breast. The tumour cells invade other healthy breast cells and can travel to lymph nodes which are a primary pathway for the cancer cells to move to other parts of the body. Symptoms of breast cancer include a lump in the breast or tissue thickening which feels different than the normal surrounding tissues, breast pain, redness, swelling, nipple discharge other than breast milk, bloody discharge, unexplained change in shape, size or appearance of the breast, peeling, flaking or scaling of the skin, and a lump or swelling under the arm.
