Ayr saline gel Ok to use inside the nose?

Generally, these products are considered safe to use on the inside of the nose.  The AYR is not a known cancer-causing agent and especially have no known association with cancers of the nasal or sinus cavities.  

Saline sprays, irrigations and gels, petroleum ointments, vaporizers are all safe effective ways to improve dry nose symptoms and prevent nose bleeds after surgery.

Ayr saline gel is a very safe product to use after your surgery. Petroleum products are also very helpful in keeping the nose moist and have been recommended for many years without any increased incidence of pneumonia or cancer. I would also recommend saline irrigations such as NeilMed Sinus Rinse which you can get over the counter.
