Why is this medication prescribed?

Ribociclib is a medication used in combination with other drugs to treat certain types of advanced or metastatic breast cancer. It belongs to a class of drugs known as cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. Ribociclib works by inhibiting the activity of specific proteins (CDK4 and CDK6) that play a role in promoting the growth of cancer cells.

How should this medicine be used?

• Combination Therapy: Ribociclib is often prescribed in combination with other medications, such as aromatase inhibitors (e.g., letrozole or anastrozole) or fulvestrant, for the treatment of hormone receptor-positive, HER2-negative advanced or metastatic breast cancer in postmenopausal women.
• Dosage: The recommended dosage can vary, and it’s crucial to follow the prescribed dose and schedule provided by the healthcare provider. Dosage adjustments may be made based on individual tolerance and side effects.
• Administration: Ribociclib is usually taken orally in the form of tablets. It is typically taken once daily with or without food. The tablets should be swallowed whole with a glass of water and not crushed, chewed, or split.
