Onxol must be administered in an appropriate medical setting. Serious allergic reactions, some fatal, have occurred with the use of Onxol. DO NOT use Onxol again if you have experienced a severe allergic reaction to it. Stop using Onxol and notify your doctor immediately if you develop signs of an allergic reaction, such as rash; itching; fainting; severe dizziness or light-headedness; swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness.

Certain patients with solid tumors or AIDS-related Kaposi sarcoma should not use Onxol. Frequent blood tests should be performed while you are using Onxol because of the risk of bone marrow suppression and serious infection.

Do not substitute or interchange Onxol with other forms of paclitaxel.


Onxol is used for:

Treating certain types of ovarian, lung, or breast cancer in certain patients. It is also used to treat AIDS-related Kaposi sarcoma in certain patients. It may also be used for other types of cancers as determined by your doctor.

Onxol is a chemotherapy medicine. It works by slowing or stopping cancer cells from dividing and growing, so they eventually die.

Do NOT use Onxol if:

  • you are allergic to any ingredient in Onxol or medicines that contain polyoxyethylated castor oil (eg, cyclosporine injection, teniposide injection)
  • you have extremely low white blood cell counts (eg, extremely low neutrophil counts)
  • you have shingles or chickenpox
  • you have taken or will be taking palifermin within 24 hours before or after using Onxol

Contact your doctor or health care provider right away if any of these apply to you.
