Warning

Paclitaxel may rarely cause serious (rarely fatal) allergic reactions. Patients who experience a severe allergic reaction with this drug must never use it again. Your doctor may prescribe other medications (such as antihistamines, corticosteroids) to help prevent an allergic reaction. However, severe allergic reactions may still occur in a few patients. Get medical help right away if you develop any signs of an allergic reaction such as rash, itching, swelling, severe dizziness, trouble breathing, or chest pain.

This medication may often cause a serious blood disorder (decreased bone marrow function leading to a low number of white blood cells). This effect can lower your body's ability to fight an infection. Your doctor will monitor you closely and check your blood often during treatment. If your white blood cell count is too low, you should not receive this medication. Tell your doctor right away if you develop any signs of infection (such as sore throat that doesn't go away, fever, chills, cough, painful/difficult urination).

Precautions

Before using paclitaxel, tell your doctor or pharmacist if you are allergic to it; or to similar drugs (taxane-type drugs such as docetaxel, cabazitaxel); or if you have any other allergies. This product may contain inactive ingredients (such as polyoxyethylated castor oil), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: blood disorders (such as low white blood cell count), decreased bone marrow function, current infections, heart problems (such as fast/slow/irregular heartbeat), high or low blood pressure, liver disease.

This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Tell your health care professional that you are using paclitaxel before having any immunizations/vaccinations. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).

Paclitaxel can make you more likely to get infections or may make current infections worse. Stay away from anyone who has an infection that may easily spread (such as chickenpox, COVID-19, measles, flu). Talk to your doctor if you have been exposed to an infection or for more details.

To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like safety razors and nail cutters, and avoid activities such as contact sports.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
