Antihistamines
Antihistamines can also be used to treat canker sores. These medications work by reducing inflammation and pain. In addition, they can help to speed up the healing process. Antihistamines are available in pill and liquid form, making them easy to take. The recommended dosage is 10 mg three times daily. Diphenhydramine and cetirizine are two common antihistamines used to treat canker sores.
There are a variety of ways antihistamines can be used to treat canker sores, including swishing and spitting a mixture of liquid antacids and antihistamines. The theory is that the antacid may neutralize the acid in the mouth and reduce inflammation, while the antihistamine may help to reduce pain and swelling. If you choose to try it, be sure to Spit out the mixture after swishing it around your mouth for a few minutes. Swallowing it could lead to nausea and vomiting. You should also avoid using this remedy if allergic to the ingredients.
