[|Human|] My sister has a really bad ulcer in her mouth.  Is there anything  that used to be sold by prescription that I can purchase at the drug store that can heal mouth ulcers.  I need a medicine that formerly was sold by prescription as the over the counter medications dont seem to work.  She used to use Triamcinolone Acetonide Paste for mouth, but she is out of it.
[|AI|]  Hi. Thanks for the query. From.your explanation it seems to be authors ulcers or canker sores. It can be a side effect of the medication, deficiency of iron and vitamin B12, stress, physical trauma to the tongue, allergies, acid reflux etc. I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis. Treatment of underlying cause will relieve the symptoms. As of now you can start gargling with a numbing mouthwash containing Lidocaine to relieve the symptoms. You can also take a multivitamin tablet daily. You can take anti-inflammatory painkiller like Ibuprofen. Suck ice and do cool water rinses. Avoid spicy food. Hope this helps. Regards.
