💊 What Is Palbociclib Used For?

Doctors prescribe Palbociclib alongside endocrine therapies, like letrozole or fulvestrant, to treat:

• Postmenopausal women with hormone receptor-positive, HER2-negative advanced breast cancer.
• Men with the same condition, usually in combination with aromatase inhibitors.

This targeted therapy is not chemotherapy. Instead, it inhibits proteins called CDK4 and CDK6 that promote cancer cell division, offering a focused approach with fewer systemic side effects.

Palbociclib blocks the proteins CDK4 and CDK6, which cancer cells need to divide and grow. By targeting these proteins, the medication slows tumor progression. Doctors combine Palbociclib with hormone therapies like letrozole or fulvestrant to improve effectiveness.

This combination targets cancer cells without causing the widespread damage typical of chemotherapy. As a result, patients often experience fewer side effects and maintain their quality of life.

⚠️ Common Side Effects

When side effects arise, healthcare providers adjust doses or recommend supportive care to keep patients on track.
