Mitomycin-C Kyowa is usually given by injection or as an infusion (with a drip). However in the treatment or the prevention of the recurrence of bladder cancer, a solution of 'Mitomycin-C' Kyowa will be given directly into the bladder through a type of tube called a catheter.

The precise dosage, frequency of dosing and duration of treatment with Mitomycin-C Kyowa will depend on your age, weight, medical condition and whether Mitomycin-C Kyowa is being given in combination with other drug treatment.

For example, when given by injection the recommended dose is in the range of 4-10 mg given at 1-6 weekly intervals. A course ranging from 40-80 mg is often required for a satisfactory result when used alone or in combination with other treatments. Thus, the period of treatment could last from just a few weeks up to a number of months, depending on the condition being treated.

In the treatment of bladder cancer, the recommended dose is 20-40mg administered into the bladder, weekly or three times a week for a total of 20 doses. The dosage may be decreased if side effects are a problem.

If during treatment you develop a dry cough, breathlessness, rapid breathing or anything else which suggests your lungs might be affected, you may require to be monitored by X-rays of your chest that could continue up to 4 weeks after the end of treatment.
