sulfonated phenolics / sulfuric acid
Used for Canker Sores

Debacterol is a topical liquid medication used to ease pain from canker sores (mouth ulcers) or other minor mouth irritations. It's made up of 50% sulfonated phenolics and 30% sulfuric acid. Debacterol belongs to a group of medications known as debriding agents, which are used to remove dead tissue in wounds. Debacterol is applied directly to the canker sore, typically for about 5 seconds as a one-time treatment by a healthcare professional, such as a dentist. Some side effects of this medication include irritation and stinging at the application site.

Pharmacist tips for Debacterol

pharmacist
  • Your healthcare professional (HCP) will typically apply Debacterol to your canker sore or mouth sore at a dental office, clinic, or hospital. This medication needs to be given by a trained HCP with the proper tools and technique to make sure it's used safely and to lower the risk of side effects.
  • Don't swallow Debacterol. This medication might be harmful if it's accidentally swallowed. After your HCP applies it to the canker sore, they'll instruct you to rinse your mouth thoroughly, then spit.
  • Let your HCP know if you feel a stinging sensation or pain after one application of Debacterol. There's a chance that they might've missed parts of the canker sore during the application. Your HCP can apply the medication again to make sure the canker sores are completely covered.
  • Debacterol should only be used in your mouth to treat canker sores or minor mouth irritations.
  • If Debacterol gets into your eyes, get medical attention right away. Your HCP will ask you to rinse your eyes with lukewarm water for 15 minutes to make sure the medication is flushed out.

Common questions about Debacterol

No. Debacterol can only be ordered by healthcare professionals for use in a clinic or hospital setting. It isn't available for purchase over the counter.

Typically, Debacterol can be applied in your mouth in places where you have canker sores (mouth ulcers), including your tongue. Your healthcare professional (HCP) will let you know whether Debacterol is appropriate to treat any sores on your tongue.

Debacterol can cause some irritation, such as a stinging sensation when it's applied. This should go away once you rinse your mouth with water and spit it out. If the pain or irritation continues, your healthcare professional might recommend you to rinse your mouth with a baking soda solution. Let your care team know if the stinging doesn't go away after a few minutes of rinsing out your mouth.

No. The manufacturer states that Debacterol should only be used for canker sores. It's not for cold sores or fever blisters, which are painful, fluid-filled sores or crusting around the lips. If you have a cold sore, ask your care team about appropriate medications (e.g., docosanol (Abreva)) that might help. Discuss the risks and benefits of each option with a healthcare professional to see what's most appropriate for you.

The manufacturer claims that most people typically feel pain relief from canker sores after one treatment of Debacterol. A small study showed that most people experienced noticeable pain relief 3 days after treatment. Ask your healthcare team if you're not sure whether Debacterol is working.

Before the application, your healthcare professional (HCP) will prepare the area for treatment by drying the canker sore(s) or ulcer(s) with a cotton swab. Then, they'll apply Debacterol to the affected area(s) inside your mouth for at least 5 seconds, but no more than 10 seconds. During this time, you might experience some stinging. Typically, the stinging from Debacterol and the pain from the canker sore should ease after you rinse your mouth with water and spit. If you still feel stinging, let your HCP know. They might give you a baking soda rinse to see if that helps. If not, there's a chance that they might've missed parts of the canker sore and will need to reapply Debacterol to those areas.

One small study showed that 80% of the canker sores in people who received Debacterol completely healed by day 6. In addition, all of the people who received Debacterol no longer experienced pain from canker sores by day 10. Follow up with your healthcare team to learn more about how well Debacterol can work to treat canker sores.
