Before applying, dry the ulcerated area of oral mucosa using a sterile cotton-tipped applicator or similar method. Apply coated applicator directly to the dried ulcer bed, holding the applicator in contact with the ulcer for at least 5 sec, but not more than 10 sec, while using a rolling motion to thoroughly coat the entire ulcer bed, the ulcer rim, and surrounding halo of normal mucosa. Then, thoroughly rinse mouth with water and spit out the water. The stinging sensation and ulcer pain should subside almost immediately after rinsing. If the ulcer pain returns shortly after rinsing with water, some part of the ulcer may not have been covered during the application. A second application should be applied to the ulcer immediately during the same treatment session until it remains pain-free after rinsing. More than 1 treatment session is not recommended on an individual mucosal ulcer.
