Can you use lidex (fluocinonide) 0.05% ointment for ulcer under the tongue inside the mouth . or is it for external use only. is it toxic if absorbed.

External use only: If applied orally, the cream is useless because it will be washed out by saliva. It will be at toxic levels if you use a large amount.Best to gargle frequently with warm salty water.

Absolutely not: Use this medicine only on your skin. Rinse it off right away if it gets on a cut or scrape. Do not get the medicine in your eyes, nose, or mouth. http://www.ncbi.nlm.nih.gov/pubmedhealth/PMHT0010336/?report=details#warning

Of course, you can: Mix Lidex (fluocinonide) 0.05% ointment with Orabase and place the mixture gently over the ulcer.
