My Mother was suffering from Mouth Ulcer. I gave her Metronidazole (400 mg) , twice in a day for a week.  She was relieved from the mouth ulcer and pain. But after one week she is again complaining for the same problem. What drug should i give to her ?
Thanks for your query, I have gone through your query, the ulcers could be authors dermatitis or herpetic ulcer or traumatic ulcer. Consult your oral physician and get it diagnosed first. For reducing pain you can take topical anesthetic and analgesics. No need to take metronidazole. Based on the diagnosis or identification of the cause we can treat accordingly. I hope my answer will help you, take care.
