Hello and thank you for posting. I am sorry that you are having this problem with excess saliva/mucus. This is can happen after this type of treatment.

Do speak to your hospital team and specialist nurse if you have one as they may be able to help support side affects you are getting.

There are some medications that can be prescribed at this time to thicken up the mucus to make it more manageable. Also sometimes salt water mouthwashes can help.

There are a couple of head and neck charities that may also be useful.

Moving this question too, and posting on the 'living with cancer' thread, may mean you get more responses from other forum users rather than from the nurses.

Take care and I hope this improves for you.

If you want to talk do give our helpline a call on 0808 800 4040. Lines are open mon-fri, 9-5.

Sarah.
