Regarding Throat Comfort Lozenges 2 mg (Benzidamine) and Gastroesophageal Reflux Disease (GERD)?


I have been experiencing throat discomfort lately and took 2 mg of Throat Comfort lozenges (Benzocaine).
Just now, while talking to someone, I accidentally swallowed the remaining third of the lozenge.
Will the ingredients in Throat Comfort cause esophageal burning or inflammation? I have already drunk about 300 milliliters of water.
Additionally, I have had gastroesophageal reflux issues for the past couple of years, but they are relatively mild.
How can I improve this condition?

Hello Mr.
Yu Guang: Preliminary research on the throat-soothing lozenges shows no such side effects.
It is recommended that you consult your physician for more clarity.
There are many causes of gastroesophageal reflux, such as coffee and sweets.
It is advisable to visit a hospital to investigate the cause and seek improvement.

Throat lozenges, such as those containing benzocaine or similar active ingredients, are generally designed to soothe throat discomfort. However, for patients with gastroesophageal reflux disease (GERD), there are several considerations to keep in mind regarding their use, particularly concerning the potential for esophageal irritation or burns.

When you accidentally swallowed a portion of a throat lozenge, the immediate concern would be the ingredients in the lozenge and their potential effects on the esophagus. Most throat lozenges are formulated to dissolve slowly in the mouth, allowing their soothing ingredients to coat the throat. However, if a lozenge is swallowed whole or partially dissolved, it may not provide the same soothing effect and could potentially irritate the esophagus, especially in individuals with GERD.

In GERD patients, the esophagus is already susceptible to irritation due to the backflow of stomach acid. The presence of any foreign substance, including lozenges, can exacerbate this condition. If the lozenge contains ingredients that are acidic or irritating, there is a risk that it could contribute to esophageal inflammation or discomfort. Symptoms of esophageal irritation may include burning sensations, pain, or difficulty swallowing.

You mentioned that you drank approximately 300 milliliters of water after swallowing the lozenge. This is a good step, as water can help dilute any potential irritants and wash them down into the stomach, where they are less likely to cause harm. However, if you experience persistent discomfort, pain, or any new symptoms such as difficulty swallowing or severe heartburn, it is advisable to seek medical attention.

To manage GERD symptoms more effectively, consider the following strategies:
1. Dietary Modifications: Avoid foods and beverages that trigger your symptoms. Common culprits include spicy foods, citrus fruits, chocolate, caffeine, and carbonated drinks. Instead, focus on a diet rich in whole grains, lean proteins, and vegetables.

2. Eating Habits: Eat smaller, more frequent meals instead of large meals. This can help reduce the pressure on the lower esophageal sphincter (LES), which is the muscle that prevents stomach contents from flowing back into the esophagus.

3. Posture: After eating, try to remain upright for at least two to three hours. Lying down can increase the likelihood of reflux.

4. Weight Management: If you are overweight, losing weight can significantly reduce GERD symptoms, as excess weight can put additional pressure on the abdomen and LES.

5. Medications: Over-the-counter antacids or proton pump inhibitors (PPIs) can help manage GERD symptoms. However, it is essential to consult with a healthcare provider before starting any new medication, especially if you have been experiencing symptoms for an extended period.

6. Avoid Smoking and Alcohol: Both smoking and alcohol can weaken the LES and exacerbate GERD symptoms.

7. Consultation with a Specialist: If your symptoms persist or worsen, consider consulting a gastroenterologist. They can provide a comprehensive evaluation and recommend appropriate treatment options tailored to your specific condition.

In summary, while swallowing a throat lozenge may not typically cause significant harm, it is essential to be mindful of how it interacts with your existing GERD condition. Monitoring your symptoms and making lifestyle adjustments can help improve your overall digestive health and reduce the risk of esophageal irritation. If you have any concerns or experience worsening symptoms, do not hesitate to reach out to a healthcare professional for guidance.
