The infusion process
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.
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.
How long does each infusion last?
Infusion times may vary from person to person depending on tolerability.
After each medication is given, your doctor or nurse will wait 30 to 60 minutes to check for any reactions. If a reaction occurs, they may adjust, delay, or stop treatment.
During your first treatment
The medicines are given more slowly during your first visit. Your first dose of PERJETA will be given as an infusion over 60 minutes. Herceptin will be given over 90 minutes, and docetaxel over 60 minutes.
How long will you stay on therapy?
Docetaxel is given for a minimum of 6 cycles. If your doctor stops docetaxel (for example, due to side effects), you can continue receiving PERJETA and Herceptin. You can stay on PERJETA and Herceptin until your disease is no longer controlled or your side effects require you to stop treatment.
If you doctor delays or stops your Herceptin treatment, then PERJETA
should also be delayed or stopped.
Side effects may occur with PERJETA
PERJETA is given together with Herceptin and docetaxel, and side effects may occur.
