Side effects of targetted bladder chemo

Hi. Im new here. I was diagnosed with low risk bladder cancer in December 2024. I had surgery, including 1 off targetted chemo at the same time in January 2025.

I had the operation again in April 2026.

I went in fir a repeat yesterday and the have done different procedure and suggesting a course of 6 weekly chemo sessions.

What are the side effects of having this 6 times?

I had very few sude effects for the 1 off but want to be prepared. 

Thanks. Em.

  • Hello and thanks for your post,

    I can understand that you would want to prepare yourself for the treatment. I am presuming that you are asking about having chemotherapy treatments inside the bladder (intravesical chemotherapy).

    Side effects can build up gradually over the courses of treatment. So it is important to report them to your hospital team so they can help you manage them.

    Common side effects experienced can include, bladder irritation, that can feel like cystitis. So feeling like passing urine more often, with urgency. There can be some burning sensation as well.

    Small amounts of blood may be passed in the urine. You may get a rash on your hands or feet for a short time after having this treatment. Some skin rashes may get red, sore and swollen. Some people get severe itching. Contact your doctor if you get any of these symptoms.

    We have information about the side effects of chemotherapy on the bladder on our website but you can find out more about bladder cancer treatments through the organisation Action Bladder Cancer UK who offer support as well.

    I hope that it goes well for you.

    Best wishes,

    Vanda
