- Chlorhexidine mouthwash used twice a day (brand name Corsodyl or Chlorohex) may reduce the pain and help to heal. Can cause staining of teeth especially after coffee/tea.
- Hydrocortisone lozenges may help symptoms and healing. The patient can use the tongue to keep the lozenge in contact with an ulcer as it dissolves. Can 'stop' the ulcer if used early enough.
- Analgesic agents can help to reduce pain. Consider Difflam or choline salicylate gel (brand name Bonjela). Note it contains Aspirin and should not be given to under 16s
- Severe cases require Colchicine, Oral Prednisone or even Azathioprine. Thalidomide has been used.
