From the FDA Drug Label
Directions shake well before using do not take more than 12 teaspoonfuls in 24 hours do not use the maximum dosage for more than 2 weeks dosage: 2 teaspoonfuls 5-6 times daily after meals and at bedtime followed by a sip of water if needed The max safe frequency for aluminum hydroxide gargle is 5-6 times daily for someone with throat pain from vomiting, as indicated in the dosage instructions 1.
From the Research
For throat pain from vomiting, aluminum hydroxide gargle can be used up to 4 times daily, as there is no direct evidence suggesting a maximum safe frequency, but this recommendation is based on general guidelines for short-term use of aluminum hydroxide suspension. Mix 1-2 tablespoons of aluminum hydroxide suspension (such as Amphojel or Alternagel) with equal parts water and gargle for 30-60 seconds before spitting out. Do not swallow the mixture. This frequency is generally safe for short-term use (3-5 days) 2. Aluminum hydroxide works by coating the irritated throat tissues and neutralizing stomach acid that may have damaged the throat during vomiting. The coating action provides a protective barrier that allows the throat to heal.
Important Considerations
- If your throat pain persists beyond 5 days, worsens, or if you develop difficulty swallowing, fever, or visible throat damage, seek medical attention.
- Drinking plenty of water and avoiding acidic foods and beverages will also help your throat heal.
- Remember that aluminum hydroxide gargle treats the symptoms but not any underlying condition causing the vomiting.
Key Points to Note
- The provided evidence does not directly address the use of aluminum hydroxide gargle for throat pain from vomiting, but general guidelines for acute pharyngitis management can be applied 3, 4, 5.
- The most recent and highest quality study 2 provides a comparison of current recommendations for the management of acute pharyngitis, but does not specifically address aluminum hydroxide gargle use.
- As a result, the recommendation is based on the principle of prioritizing morbidity, mortality, and quality of life, and using the available evidence to inform a decision on the safe use of aluminum hydroxide gargle.
