Canker Sore Formulas

The Canker Sore Formula is a customized prescription blend that targets the main symptoms of recurrent ulcerated lesions found in the mouth. It is a topical solution typically applied directly to the site once daily as needed.

What is the Canker Sore Formula?

The Canker Sore Formula combines prescription ingredients in a proprietary base developed specifically to deliver ingredients to the affected area(s). Although it burns when applied, the sore is essentially instantly cauterized, and in most cases no further symptoms are reported. An accumulating body of evidence suggests that polyphenols play a pivotal part in the management of ulcers. It has been confirmed that dietary polyphenols possess protective and therapeutic potential in peptic ulcers.

Common Ingredients

Polyphenol Sulfonic Acid Complex

Research has shown polyphenol compounds may reduce the growth and pain of lesions found in recurrent canker sores by providing anti-inflammatory, antioxidant, and caustic properties.

Frequently asked questions

What is a compounded medication?

One size doesn’t fit all and every patient is unique. Drug compounding is the process of combining, mixing, or altering ingredients to create a medication tailored to the needs of a patient by a pharmacist as the result of a practitioner’s prescription drug order. While compounded medications are not FDA-approved, they serve an important patient need—especially when FDA-approved medication is not available for treatment. Our formulations are made to order in small batches to ensure freshness. The specific ingredients in your compounded formula will depend on your specific concerns and goals. It should be understood that your personal healthcare practitioner will make the final decision.

Are compounded medications FSA & HSA eligible?

Yes! All of our compounded formulations, regardless of ingredients, are eligible for Flexible Spending Accounts (FSA) and Health Saving Accounts (HSA).

What is a canker sore?

Canker sores may be recurring and can last for two weeks or more.

When should I see improvement in my symptoms?

Based on research and patient testimonials, you may see improvement as early as 30 to 60 seconds after application; however, each patient is unique and time frames may differ.
