Explanation:

Vincristine is a drug for injection that is used to treat individuals with different types of cancer including leukemia, lung and breast cancer. Its action is to interfere with amino acid metabolism and prevent cell division, reducing the likelihood of cancer spreading throughout the body. This medicine can cause unpleasant reactions in the individual and is therefore often used in conjunction with diphenhydramine.

Diphenhydramine is an antihistamine used as a solution for injection for acute symptom control, for uncomplicated allergic conditions when oral therapy of a drug may cause unpleasant patient symptoms such as nausea or severe feeling sick. This medicine is indicated for patients who are unable to tolerate more potent substances of vincristine, as it has the ability to decrease the incidence of a reaction to vincristine.
