PACL
PACLitaxel-Trastuzumab Treatment
This document provides general information about your cancer treatment. It does not replace the advice of your health care professional. Always discuss your therapy with your health care team.
This treatment consists of PACLitaxel and Trastuzumab (Herceptin®).
Refer to the medication information sheet for each drug for more information
- PACLitaxel-Trastuzumab is a drug combination for treating HER2 receptor positive breast cancer.
- Intravenous medications (dexamethasone, ranitidine and diphenhydramine) will be given to you to prevent allergic reactions. Instead of or in addition to intravenous dexamethasone, your doctor may prescribe dexamethasone tablets for you to take at home before your paclitaxel treatment. It is important that you take the dexamethasone tablets exactly as prescribed by your doctor.
- It is important to tell your oncologist about any other medical conditions you have, as some conditions may affect therapy with this treatment.
- Since these medications may harm your baby if used during pregnancy, women who have not yet reached menopause should use effective forms of birth control while being treated. Do not use birth control pills. Please discuss this with your oncologist.
- If you become pregnant, tell your oncologist right away.
- Do not breastfeed while undergoing treatment.
- Also, if you plan to have children, discuss this with your oncologist before starting your first treatment, as chemotherapy may affect your fertility and your chances of having a baby in the future.
- Your oncologist will determine how many treatment cycles you need depending on how you tolerate and respond to the chemotherapy. Each cycle lasts 3 weeks (21 days). You will receive trastuzumab and paclitaxel through a vein in your arm (IV) on first day (Day 1) of each cycle. Days 2 to 21 are rest days.
- Your oncologist may decide on an alternate schedule that could include weekly doses of paclitaxel with either weekly trastuzumab or trastuzumab every 3 weeks.
- You will have a blood test before each treatment to check if your blood counts are high enough for you to receive the next cycle of chemotherapy
- Allergic reactions can occur during the infusion of paclitaxel. Symptoms of an allergic reaction include: lower back pain, flushing, shortness of breath, swelling, chest pain, dizziness, itching and rash. Your nurse will watch you closely, especially at the beginning of each treatment, when paclitaxel will be given at a slower rate. Tell your nurse if you are experiencing any type of discomfort as soon as they occur. You may experience these symptoms even after you leave the cancer centre. Please contact your oncologist if these symptoms occur. Please go to the nearest emergency department if you experience signs of an allergic reaction after you have been discharged.
- Trastuzumab, rarely, can have an effect on the function of the heart, which in some patients might cause shortness of breath, palpitations, fatigue and leg swelling. Your oncologist will order special heart tests before you begin treatment and while you are on treatment to follow your heart function. Tell your oncologist if you have had any heart problems and if you experience any of these symptoms.
- Medications in this regimen may make your periods heavier or lighter. Your periods may even stop completely. This may be permanent. You may develop symptoms of menopause such as hot flashes, vaginal dryness, mood swings and changes in sexual desire. Please discuss any concerns with your nurse or oncologist.
- Tell your oncologist, nurse, and pharmacist about any other prescription and non-prescription medications you are currently taking. Check with your oncologist, nurse or pharmacist before you start taking any new drugs, including herbal or alternative treatments. Also, tell other healthcare professionals you are seeing about the chemotherapy you are receiving.
- Due to increased risk of developing infections, check with your oncologist before having any vaccinations. Also check with your oncologist before any surgery or dental work.
- If you are taking ASA (Aspirin®, acetylsalicylic acid), please discuss this with your oncologist as this may interfere with your chemotherapy treatment. For headache, or occasional aches and pains, use acetaminophen (Tylenol®) instead of ASA.
