Which of the following drugs is NOT commonly associated with Myelosuppression?

  1. Cisplatin

  2. Bleomycin

  3. Vincristine

  4. Cyclophosphamide

The correct answer is: Bleomycin

The other options, A, C, and D, are commonly associated with Myelosuppression. Cisplatin is a chemotherapy drug that can lead to a decrease in the production of bone marrow cells. Vincristine is a medication commonly used in cancer treatment that can also cause Myelosuppression by killing off bone marrow cells. Cyclophosphamide is another chemotherapy drug that can suppress bone marrow, leading to decreased blood cell production. Bleomycin, on the other hand, does not commonly cause Myelosuppression, making it the correct answer.
