The Active Ingredient: Benzocaine and Its Risks
The primary concern with swallowing medicated Orajel gel lies in its active ingredient, benzocaine. Benzocaine is a local anesthetic that works by temporarily blocking nerve signals in the area where it's applied. When applied topically to the gums, it provides fast, targeted relief for toothaches or minor oral irritations. However, the product is formulated for external, oral mucosal use only and is not meant to be absorbed systemically.
The Danger of Ingesting Benzocaine
When swallowed, particularly in significant quantities or by a vulnerable individual, benzocaine can trigger a rare but very serious condition called methemoglobinemia. This disorder affects the hemoglobin in red blood cells, converting it into methemoglobin, which cannot carry oxygen effectively to the body's tissues. The result is a dangerously low level of oxygen in the blood, which can be life-threatening.
Infants and young children are at a significantly higher risk due to their smaller size and lower levels of the enzyme that breaks down methemoglobin. In fact, the FDA has warned against the use of benzocaine products for teething pain in children under two, noting that the benefits do not outweigh the risks. Additionally, adults with pre-existing conditions like asthma, heart disease, or certain genetic enzyme deficiencies are more susceptible to complications.
What Happens If You Swallow Orajel?
Accidentally swallowing a small amount of Orajel during proper application may not cause a severe reaction in a healthy adult, but it is never without risk and should be avoided. Signs and symptoms of methemoglobinemia can appear within minutes to an hour or two after exposure and include:
- Pale, gray, or blue-colored skin, lips, and nail beds (cyanosis)
- Shortness of breath or difficulty breathing
- Fatigue or unusual tiredness
- Headache
- Dizziness or lightheadedness
- Rapid heart rate
- Confusion
If you observe any of these symptoms after using Orajel, or suspect accidental ingestion, especially in a child, you must seek emergency medical attention immediately. A call to the Poison Help line (1-800-222-1222 in the U.S.) is also recommended for immediate guidance.
Safe Alternatives and Proper Use
When using medicated Orajel products, always follow the package directions carefully. Apply only a small amount directly to the affected area using a cotton swab or fingertip. Use the smallest amount necessary for relief and no more than the frequency recommended on the package. Be sure to avoid eating or drinking for at least an hour after application to prevent accidentally swallowing the gel. Store the medication securely out of the reach of children.
For infant teething, the FDA and American Academy of Pediatrics recommend safer, non-medicated alternatives instead of benzocaine gels. These include giving the baby a chilled (not frozen) teething ring or gently massaging their gums with a clean finger.
Comparison: Medicated vs. Non-Medicated Orajel Products
| Feature | Medicated Orajel (with Benzocaine) | Non-Medicated Orajel (e.g., Orajel Baby) |
|---|---|---|
| Active Ingredient | Contains benzocaine as a local anesthetic. | Does not contain benzocaine or other anesthetics. |
| Recommended Use | For temporary, topical relief of oral pain in adults and children aged 2 and older (with precautions). | Marketed for teething, but efficacy is limited and use is discouraged by experts. |
| Risk of Ingestion | High-risk due to potential for methemoglobinemia, especially for infants and children. | Very low risk, as ingredients are not dangerous when ingested. |
| FDA Recommendation | Not for infants/children under 2. Adults and older children should use with warnings. | Discouraged for teething as it quickly washes away and offers minimal benefit. |
| Primary Mechanism | Numbing effect by blocking nerve signals. | Non-pharmacological, provides soothing cooling sensation. |
Conclusion
Swallowing Orajel gel that contains the active ingredient benzocaine is not safe and carries a significant health risk, most notably methemoglobinemia. All users, particularly adults, must exercise caution and adhere strictly to the product's topical application instructions. For parents and caregivers, the advice is even more clear: avoid using benzocaine products for infant teething and opt for safer, non-medicinal remedies. By understanding the real risks and following safe usage guidelines, you can protect yourself and your family from potentially serious consequences. Remember, if you suspect accidental ingestion or observe any signs of an adverse reaction, seek immediate medical help or contact a poison control center. For more information on benzocaine safety, you can refer to the FDA's official drug safety communication.
