What should we do before using Paclitaxel?

Paclitaxel is a mitotic inhibitor used in cancer chemotherapy. It was discovered in a US National Cancer Institute program at the Research Triangle Institute in 1967 when Monroe E. Wall and Mansukh C. Wani isolated it from the bark of the Pacific yew tree, Taxus brevifolia and named it taxol. Later it was discovered that endophytic fungi in the bark synthesize paclitaxel.

While offering substantial improvement in patient care, paclitaxel has been a relatively controversial drug. There was originally concern because of the environmental impact of its original sourcing (no longer used) from the Pacific yew. In addition, the assignment of rights to Bristol-Myers Squibb, and even the name itself, were the subject of public debate and Congressional hearings. So before using Paclitaxel, you should know some warnings about it, in this article, I will give you some warnings.

1. Before using paclitaxel, tell your doctor or pharmacist if you are allergic to it; 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.

3. Do not have immunizations/vaccinations without the consent of your doctor, and avoid contact with people who have recently received polio vaccine by mouth or flu vaccine inhaled through the nose. Since this medication can increase your risk of developing serious infections, wash your hands well to prevent the spread of infections. Avoid contact with people who have illnesses that may spread to others (e.g., flu, chickenpox).

4. 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.
