Topical Anesthetic Benzocaine: Safe Use and Side Effects
Summary
Benzocaine is a topical anesthetic used to numb the gums and mouth sores, providing quick relief from pain. It comes in the form of a spray or gel and works almost instantly, within 5 to 15 seconds. While generally safe, some side effects can occur. Understanding how to use it properly can help you avoid these issues and make the most of its benefits.
What Is This & Why It Matters
Benzocaine is a medication that helps numb specific areas in the mouth, making it useful for treating mouth sores or gum pain. By reducing sensation, it helps alleviate discomfort during activities like eating or speaking. The American Dental Association (ADA) highlights its effectiveness when used as directed. However, it's important to be aware of potential side effects and ensure proper application to maximize safety.
What You Should Do
- Apply benzocaine directly to the affected area using clean fingers or a cotton swab.
- Wait for 5-15 seconds for the numbing effect to kick in before eating or drinking.
- Hold your breath while spraying to prevent inhaling the medication.
- Reapply every two hours if needed but do not exceed the recommended dosage.
- Store benzocaine in a cool, dry place out of reach of children.
- Reach out to your dentist if your symptoms persist despite treatment.
What You Should NOT Do
- Do not apply benzocaine to large areas of broken skin.
- Avoid swallowing the gel or spray; it's for external use only.
