When administered as sequential infusions, taxane derivatives should be administered before platinum derivatives (cisplatin, carboplatin) to limit myelosuppression and to enhance efficacy
Contra Indications
Previous severe hypersensitivity reaction to docetaxel, the solvent or polysorbate 80. Severe neutropenia; pregnancy, severe liver impairment.
Precautions
Lactation. Hepatic impairment. Monitor liver blood function and blood counts regularly. Premedication with oral dexamethsaone at 16 mg daily for 3 days, starting one day before docetaxel treatment is recommended.
Lactation: Not known if excreted in breast milk, do not nurse
Pregnancy-Lactation
Pregnancy
Based on findings in animal reproduction studies and its mechanism of action, therapy can cause fetal harm when administered to a pregnant woman; limited available human data are not sufficient to inform drug-associated risk during pregnancy
Verify the pregnancy status of females of reproductive potential prior to initiating therapy
Contraception
Females of reproductive potential: Use effective contraception during treatment and for 6 months following last dose
Males with female partners of reproductive potential: Use effective contraception during treatment and for 3 months following last dose
Infertility
Based on findings in animal studies, therapy may impair fertility in males of reproductive potential
Lactation
There is no information regarding presence of docetaxel in human milk, or effects on milk production or the breast-fed child; no lactation studies in animals have been conducted; because of potential for serious adverse reactions in a breast-fed child from docetaxel exposure, including toxic death, hepatotoxicity, neutropenia, and acute myeloid leukemia, advise women not to breastfeed during treatment and for 2 weeks after last dose
Interactions
CYP3A4 inducers, inhibitors, or substrates may alter docetaxel metabolism.

It binds to the free tubulin and promotes the assembly of tubulin into stable microtubules while simultaneously inhibiting their disassembly, resulting in inhibition of mitosis.
