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 into the bloodstream through a vein.

PERJETA is given every 3 weeks as an IV infusion for 1 year (up to 18 cycles)

PERJETA and Herceptin® (trastuzumab) are given back-to-back at the same visit. You will also get chemotherapy as part of your treatment, but it may be on a different schedule.

If you start PERJETA + Herceptin-based therapy before surgery, you may continue to get it after surgery to complete 1 year (up to 18 cycles).*

*Unless side effects become too difficult to manage, or the cancer comes back sooner.

How long will each infusion last?

PERJETA-based therapy infusions take 30-90 minutes. Chemo infusion times vary.

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.

Your doctor will decide what chemotherapy regimen is right for you

When you have diarrhea, it means you have loose or watery bowel movements that happen 3 or more times in a day.

Some tips you can try: 

  • Choose nutritious foods, rather than foods that are greasy, fatty, or spicy
  • Eat small, frequent meals of foods that are easy to digest, such as rice, applesauce, and canned fruit
  • Drink plenty of clear, noncarbonated fluids
  • Eat foods high in potassium, such as bananas or potatoes, or drink sports drinks

You may become constipated during treatment and find you have difficulty having a bowel movement.

Some tips you can try: 

  • Drink plenty of liquids
  • Eat high-fiber foods, such as whole-grain breads and cereals, fruits and vegetables, and nuts, seeds, and popcorn
  • Be physically active if you can

Fatigue is a feeling of being tired or exhausted that may affect your ability to perform normal activities.

Some tips you can try: 

  • Be physically active each day, if your doctor approves. This may help improve your appetite, strength, and weight
  • Participate in activities during the time of day when you have more energy
  • Do the most important tasks first

Hair loss (also called alopecia) may happen on any part of the body. It may happen suddenly or a little at a time, and may cause the hair to become thin, dry, or dull.

Some tips you can try: 

  • Use a mild shampoo, and try not to wash your hair every day
  • 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

Nausea is when you feel sick to your stomach. This can lead vomiting—when you throw up.

Some tips you can try: 

  • Try relaxation techniques, such as deep breathing or thinking of a positive image or scene, to distract you from feeling sick to your stomach
  • Choose foods that are nutritious and avoid foods that are greasy, fried, salty, sweet, or spicy
  • If the smell of a food bothers you, try cooling it down before eating it
