Care During Chemotherapy and Beyond
Generic Name: Paclitaxel
Other Trade Name: Onxal TM
What is Taxol? Taxol is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy
drug. Taxol is classified as a "plant alkaloid," a "taxane" and an "antimicrotubule
agent." (For more detail, see "How Taxol Works" section below).
What Taxol Is Used For:
- Taxol is used for the treatment of breast, ovarian, lung, bladder, prostate, melanoma,
esophageal, as well as other types of solid tumor cancers. It has also been used
in Kaposi's sarcoma.
Note: If a drug has been approved for one use, physicians sometimes elect
to use this same drug for other problems if they believe it might be helpful.
How Taxol Is Given:
- Taxol is given as an injection or infusion into the vein (intravenous, IV).
- Taxol is an irritant. An irritant is a chemical that can cause inflammation
of the vein through which it is given. If the medication escapes from the
vein it can cause tissue damage. The nurse or doctor who gives Taxol must
be carefully trained. If you experience pain or notice redness or swelling
at the IV site while you are receiving Taxol, alert your health care professional
- Because severe allergic reactions have occurred in some people taking Taxol, you
will be asked to take medications to help prevent a reaction. Your doctor
will prescribe the exact regimen.
- Taxol is given over various amounts of times and in various schedules.
- There is no pill form of Taxol.
- The amount of Taxol and the schedule that it is given will receive depend on many
factors, including your height and weight, your general health or other health problems,
and the type of cancer or condition being treated. Your doctor will determine
your dose and schedule.
Taxol Side Effects:
Important things to remember about Taxol side effects include:
- Most people do not experience all of the Taxol side effects listed.
- Taxol side effects are often predictable in terms of their onset and duration.
- Taxol side effects are almost always reversible and will go away after treatment
- There are many options to help minimize or prevent Taxol side effects.
- There is no relationship between the presence or severity of Taxol side effects
and the effectiveness of the medication.
- The Taxol side effects and their severity vary depending on how much of the drug
is given, and/or the schedule in which it is given.
The following Taxol side effects are common (occurring in greater than 30%) for
patients taking Taxol:
- Low blood counts.
Your white and red blood cells and platelets may temporarily decrease. This
can put you at increased risk for infection, anemia and/or bleeding.
- Hair loss
and myalgias, pain in the joints and muscles. Usually temporary occurring 2
to 3 days after Taxol, and resolve within a few days.
- Peripheral neuropathy
(numbness and tingling of the hands and feet)
- Nausea and vomiting
- Mouth sores
reaction - fever, facial flushing, chills, shortness of breath, or hives
after Taxol is given. The majority of these reactions occur within the
first 10 minutes of an infusion. Notify your healthcare provider immediately
(premedication regimen has significantly decreased the incidence of this reaction).
The following are less common side effects (occurring in 10-29%) for patients receiving
- Swelling of the feet or ankles (edema).
- Increases in blood tests measuring liver function. These return to normal
once treatment is discontinued. (see liver problems).
- Low blood pressure (occurring during the first 3 hours of infusion).
- Darkening of the skin where previous radiation treatment has been given (radiation
recall - see skin reactions).
- Nail changes (discoloration of nail beds - rare) (see skin reactions).
Nadir: 15-21 days
This list includes common and less common side effects for individuals taking Taxol.
Side effects that are very rare, occurring in less than 10% of patients, are not
listed here. However, you should always inform your health care provider if
you experience any unusual symptoms.
When To Contact Your Doctor or Health Care Provider:
Contact your health care provider immediately, day or night, if you should experience
any of the following symptoms:
- Fever of 100.4° F (38° C), chills (possible signs of infection)
- Shortness of breath, wheezing, difficulty breathing, closing up of the throat, swelling
of facial features, hives (possible allergic reaction).
The following symptoms require medical attention, but are not an emergency.
Contact your health care provider within 24 hours of noticing any of the following:
- If you notice any redness or pain at the site of injection
- Nausea (interferes with ability to eat and unrelieved with prescribed medication)
- Vomiting (vomiting more than 4-5 times in a 24 hour period)
- Diarrhea (4-6 episodes in a 24-hour period)
- Unusual bleeding or bruising
- Black or tarry stools, or blood in your stools or urine
- Extreme fatigue (unable to carry on self-care activities)
- Mouth sores (painful redness, swelling or ulcers)
- Yellowing of the skin or eyes
- Swelling of the feet or ankles. Sudden weight gain
- Signs of infection such as redness or swelling, pain on swallowing, coughing up
mucous, or painful urination.
Always inform your health care provider if you experience any unusual symptoms.
- Before starting Taxol treatment, make sure you tell your doctor about any other
medications you are taking (including prescription, over-the-counter, vitamins,
herbal remedies, etc.). Do not take aspirin, or products containing
aspirin unless your doctor specifically permits this.
- Do not receive any kind of immunization or vaccination without your doctor's approval
while taking Taxol.
- Inform your health care professional if you are pregnant or may be pregnant prior
to starting this treatment. Pregnancy category D (Taxol may be hazardous to
the fetus. Women who are pregnant or become pregnant must be advised of the
potential hazard to the fetus).
- For both men and women: Do not conceive a child (get pregnant) while taking Taxol.
Barrier methods of contraception, such as condoms, are recommended. Discuss with
your doctor when you may safely become pregnant or conceive a child after therapy.
- Do not breast feed while taking Taxol.
Taxol Self Care Tips:
- Taxol, or the medications that you take with Taxol may cause you to feel dizzy or
drowsy. Do not operate any heavy machinery until you know how you respond to Taxol.
- If you notice any redness or pain at the injection site, place a warm compress,
and notify your healthcare provider.
- Drink at least two to three quarts of fluid every 24 hours, unless you are instructed
- You may be at risk of infection so try to avoid crowds or people with colds and
those not feeling well, and report fever or any other signs of infection immediately
to your health care provider.
- Wash your hands often.
- To help treat/prevent mouth sores, use a soft toothbrush, and rinse three times
a day with 1/2 to 1 teaspoon of baking soda and/or 1/2 to 1 teaspoon of salt mixed
with 8 ounces of water.
- Use an electric razor and a soft toothbrush to minimize bleeding.
- Avoid contact sports or activities that could cause injury.
- Taxol causes little nausea. But if you should experience nausea, take anti-nausea
medications as prescribed by your doctor, and eat small frequent meals. Sucking
on lozenges and chewing gum may also help.
- Acetaminophen or ibuprophen may help relieve discomfort from fever, headache and/or
generalized aches and pains. However, be sure to talk with your doctor before
- You may experience drowsiness or dizziness; avoid driving or engaging in tasks that
require alertness until your response to the drug is known.
- Taxol will make you sensitive to sunlight. You must wear sunglasses when outside,
and avoid sun exposure. Wear protective clothing, and also wear SPF 15 (or higher)
- In general, drinking alcoholic beverages should be kept to a minimum or avoided
completely. You should discuss this with your doctor.
- Get plenty of rest.
- Maintain good nutrition.
- If you experience symptoms or side effects, be sure to discuss them with your health
care team. They can prescribe medications and/or offer other suggestions that
are effective in managing such problems.
Monitoring and Testing While Taking Taxol:
You will be checked regularly by your health care professional while you are taking
Taxol, to monitor side effects and check your response to therapy. Periodic
blood work to monitor your complete blood count (CBC) as well as the function of
other organs (such as your kidneys and liver) will also be ordered by your doctor.
How Taxol Works:
Cancerous tumors are characterized by cell division, which is no longer controlled
as it is in normal tissue. "Normal" cells stop dividing when they come
into contact with like cells, a mechanism known as contact inhibition. Cancerous
cells lose this ability. Cancer cells no longer have the normal checks and
balances in place that control and limit cell division. The process of cell
division, whether normal or cancerous cells, is through the cell cycle. The
cell cycle goes from the resting phase, through active growing phases, and then
to mitosis (division).
The ability of chemotherapy to kill cancer cells depends on its ability to halt
cell division. Usually, the drugs work by damaging the RNA or DNA that tells
the cell how to copy itself in division. If the cells are unable to divide,
they die. The faster the cells are dividing, the more likely it is that chemotherapy
will kill the cells, causing the tumor to shrink. They also induce cell suicide
(self-death or apoptosis).
Chemotherapy drugs that affect cells only when they are dividing are called cell-cycle
specific. Chemotherapy drugs that affect cells when they are at rest are called
cell-cycle non-specific. The scheduling of chemotherapy is set based on the
type of cells, rate at which they divide, and the time at which a given drug is
likely to be effective. This is why chemotherapy is typically given in cycles.
Chemotherapy is most effective at killing cells that are rapidly dividing.
Unfortunately, chemotherapy does not know the difference between the cancerous cells
and the normal cells. The "normal" cells will grow back and be healthy but in the
meantime, side effects occur. The "normal" cells most commonly affected by
chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and
the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea,
and/or hair loss. Different drugs may affect different parts of the body.
Taxol belongs to a class of chemotherapy drugs called plant alkaloids. Plant alkaloids
are made from plants. The vinca alkaloids are made from the periwinkle plant
(catharanthus rosea). The taxanes are made from the bark of the Pacific Yew tree
(taxus). The vinca alkaloids and taxanes are also known as antimicrotubule
agents. The podophyllotoxins are derived from the May Apple plant. Camptothecan
analogs are derived from the Asian "Happy Tree" (Camptotheca acuminata). Podophyllotoxins
and camptothecan analogs are also known as topoisomerase inhibitors. The plant
alkaloids are cell-cycle specific. This means they attack the cells during
various phases of division.
- Vinca alkaloids: Vincristine, Vinblastine and Vinorelbine.
- Taxanes: Taxol and Docetaxel.
- Podophyllotoxins: Etoposide and Tenisopide.
- Camptothecan analogs: Irinotecan and Topotecan.
Antimicrotubule agents (such as Taxol), inhibit the microtubule structures within
the cell. Microtubules are part of the cell's apparatus for dividing and replicating
itself. Inhibition of these structures ultimately results in cell death.
