I am not sure what HU is, but I get mouth sores from cancer treatments and I use it. It is the only thing that makes the ulcers feel better allowing me to eat and in some cases, even talk.
I use salt and baking soda for prevention, and it does mean I get less of them and mostly smaller, but when I get them I use the mouthwash, it has lidocaine, an antacid and a few other things.
I do get it from my compounding pharmacy but it cost 32.00, regular price.
What is HU?
