A member asked:

Anyone know any prescription medication for mouth sores that works better than otc stuff?

A doctor has provided 1 answer

Acyclovir: If you get aphthous ulcers (cold or canker sores) frequently then the prescription medicine Acyclovir could help. But you usually have to get it going before you see a sore....Like at the first inkling.

Dr Villaplana agreed
