Important Safety Information for Mitomycin for Injection, USP, 20mg and 40mg:

WARNING


Mitomycin should be administered under the supervision of a qualified physician experienced in the use of
cancer chemotherapeutic agents. Appropriate management of therapy and complications is possible only
when adequate diagnostic and treatment facilities are readily available.


Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to
overwhelming infections in an already compromised patient, is the most common and severe of the toxic
effects of mitomycin.


Hemolytic Uremic Syndrome (HUS) a serious complication of chemotherapy, consisting primarily of
microangiopathic hemolytic anemia, thrombocytopenia, and irreversible renal failure, has been reported in
patients receiving systemic mitomycin. The syndrome may occur at any time during systemic therapy with
mitomycin as a single agent or in combination with other cytotoxic drugs; however, most cases occur at
doses ≥ 60 mg of mitomycin. Blood product transfusion may exacerbate the symptoms associated with this
syndrome.
The incidence of the syndrome has not been defined.


WARNINGS AND PRECAUTIONS

Mitomycin is contraindicated in patients who have demonstrated a hypersensitive or idiosyncratic reaction to it in the
past as well as in patients with thrombocytopenia, coagulation disorder, or an increase in bleeding tendency due to
other causes.

The following warnings and precautions should be taken when administering Mitomycin for Injection, USP:

• Patients be must be observed carefully during and after treatment.

events.
• Acute shortness of breath and severe bronchospasm have been reported following administration of vinca
alkaloids in patients who had previously or simultaneously received mitomycin.
• Respiratory distress syndrome may occur. Caution should be exercised using only enough oxygen to provide
adequate arterial saturation since oxygen itself is toxic to the lungs.
• Follow proper handling and disposal of anticancer drugs.

The following adverse reactions have been reported: bone marrow toxicity, integument and mucous membrane
toxicity, renal toxicity, pulmonary toxicity, hemolytic uremic syndrome, and cardiac toxicity.
