Paclitaxel (Taxol) is a chemotherapy medication used to treat many cancers, including breast cancer, ovarian cancer, and lung cancer. It’s commonly used off-label as well for other types of cancers. Typically, paclitaxel (Taxol) is given as an infusion through the veins (IV). It’s likely that you’ll receive it in combination with other anticancer medications. Since paclitaxel (Taxol) can cause serious allergic reactions, your provider will ask you to take medications to prevent reactions before each dose.
Breast cancer, after surgery or for relapsed or metastatic disease
Advanced or metastatic non-small cell lung cancer, together with platinum-based chemotherapy
Ovarian cancer, together with platinum-based chemotherapy as first-choice treatment, or alone after other treatments have stopped working
AIDS-related Kaposi sarcoma, after first-choice treatment has stopped working
Paclitaxel (Taxol) is a chemotherapy medication that works by blocking cells from growing. Cells have substances called microtubules inside them, which are important for maintaining cell structure and normal functioning. Paclitaxel (Taxol), also known as a microtubule inhibitor, interferes with normal microtubule growth. By doing so, it stops rapidly dividing cells (like tumor cells) from growing and spreading.

Commonly causes hair loss
Can cause serious allergic reactions
You’ll receive premedications, such as acetaminophen (Tylenol), diphenhydramine (Benadryl), corticosteroids, and famotidine (Pepcid AC) to prevent allergic reaction with the paclitaxel (Taxol) infusion. Also, your treatment team will likely start your first few infusions at a slower rate to lower your risk for an allergic reaction to the paclitaxel (Taxol) infusion.
Alert your care team immediately if you've symptoms of an allergic reaction during your paclitaxel (Taxol) infusion, such as feeling flushed or dizzy, or having trouble breathing. If so, your team will pause the paclitaxel (Taxol) infusion and give supportive medications to manage the reaction. Once your condition improves, your team might restart the infusion at a slower rate and adjust your premedications for future infusions.
On occasion, paclitaxel (Taxol) can irritate the area around where you’re receiving the infusion, especially if it leaks out of the vein and into the surrounding tissue (extravasation). During your infusion, let your treatment team know if you notice redness, pain, swelling, or blistering near your IV site. They might need to pause the infusion and give you a warm compress or other supportive medications to help manage the irritation.
Paclitaxel (Taxol) can damage the nerves. Let your provider know if you have new or worsening tingling in your hands or feet (peripheral neuropathy). These could be signs of nerve problems due to paclitaxel (Taxol). Your provider might need to lower your dose or have you take a short break from paclitaxel (Taxol) treatment while your nerve symptoms resolve.
Paclitaxel (Taxol) can affect your white blood cells, which raises your risk for infection. If you have a fever higher than 100.4°F, contact your healthcare team so you can get treatment for infection.
It’s common to have hair loss (alopecia) with paclitaxel (Taxol) treatment. Generally, your hair will grow back after you stop treatment, but might take 3-6 months to come back. Your hair might also grow back with a different color or texture than before.
Paclitaxel (Taxol) is transferred through breastmilk, so you should avoid breastfeeding while receiving this medication and for 2 weeks after your last dose.
Paclitaxel (Taxol) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: First or second paclitaxel (Taxol) infusion
Paclitaxel (Taxol) can cause serious allergic reactions, including symptoms such as dizziness, trouble breathing, swelling in your lips or tongue, itching, or hives. In rare cases it could be fatal. Usually, these reactions happened with the first or second paclitaxel (Taxol) infusion. To prevent a serious reaction, your provider will give you pretreatment medications, including a corticosteroid, an antihistamine, and a histamine-2 (H2) blocker.
If you have a reaction to paclitaxel (Taxol), your treatment team will pause the infusion and give medications to treat the reaction. Once your symptoms improve, your team might try to restart the infusion at a slower rate. If you have a severe reaction to paclitaxel (Taxol), you might need to go to the hospital for monitoring. After a severe reaction to paclitaxel (Taxol), your provider might recommend desensitization, where you’ll be closely monitored while you get small doses of paclitaxel (Taxol) slowly to help you tolerate treatment. Or, they might change your treatment plan altogether.
Paclitaxel (Taxol) should only be given by a trained healthcare provider in a facility that is licensed to give this medication. Because of the risk of serious side effects, such as allergic reaction, the facility needs to be equipped to treat those complications.
Risk factors: Higher paclitaxel (Taxol) dose
[EDITOR|DRUG_DISPLAY_NAME|||title]] can damage the bone marrow and cause low blood cell counts. This can lead to fatigue due to low red blood cells, higher risk of bleeding due to low platelets, and higher risk of infection due to low white blood cell counts.
Let your healthcare team know if you have unusual bleeding or bruising, or signs of infection, like a fever. Before every infusion, your provider will check your blood tests to make sure your white blood cell levels are at a safe level. If your white blood cell counts are low, your provider will delay your infusion. They might also adjust your dose for future treatments if your blood cell counts go too low. You won’t be able to receive paclitaxel (Taxol) if your neutrophil count is too low (less than 1,500 cells/mm^3^ in most cases).
In very rare situations, people receiving paclitaxel (Taxol) developed abnormal heart rhythms, which required a pacemaker in some cases. Let your provider know if you feel a racing or fluttering heart beat, or dizziness. They can check your heart rhythm to make sure paclitaxel (Taxol)’s still safe for you.
