The infusion process

Calendar showing 3 weeks icon

PERJETA is given every 3 weeks as an IV infusion

PERJETA is given as an intravenous (IV) infusion, which means that medication is administered directly and slowly into the bloodstream through a vein.

PERJETA-based therapy for Metastatic Breast Cancer IV infusion every 3 weeks

When you begin treatment, your doctor will start PERJETA, Herceptin® (trastuzumab), and docetaxel at the same time, and may adjust the medicines in your treatment plan over time.

If your doctor stops your docetaxel, you may still take PERJETA and Herceptin. If your doctor delays or stops Herceptin treatment, then PERJETA should also be delayed or stopped.

  • Avoid perming, curling, straightening, or blow-drying with high heat
  • Apply a broad-spectrum sunscreen to the scalp, or cover the scalp with a sun-protective hat or scarf when outside

  • Do the most important tasks first

A rash is an area of irritated or swollen skin. Many rashes are itchy, red, painful, and irritated.
