From the Guidelines
The recommended dose of Gas-X (simethicone) for adults and children 12 years and older is 125 to 250 mg after meals and at bedtime, not exceeding 500 mg per day. For children 2 to 12 years old, the recommended dose is 40 mg four times daily. Simethicone works by changing the surface tension of gas bubbles in the stomach and intestines, causing them to break up and allowing the gas to be more easily eliminated through belching or passing flatus. It's essential to note that simethicone only treats the symptom of gas and bloating, not the underlying cause. The medication typically begins working within 30 minutes of taking it and can be taken as needed for symptom relief. If symptoms persist for more than two weeks or worsen, it's advisable to consult a healthcare provider as this could indicate a more serious condition requiring different treatment. Simethicone is generally considered safe with few side effects, making it appropriate for short-term use to relieve occasional gas and bloating. Some key points to consider when using simethicone include:
- Taking the medication after meals and at bedtime to help alleviate symptoms
- Not exceeding the recommended daily dose of 500 mg
- Monitoring symptoms and consulting a healthcare provider if they persist or worsen
- Being aware that simethicone only treats symptoms, not the underlying cause of gas and bloating. Unfortunately, none of the provided studies 1 directly address the recommended dose of Gas-X (simethicone) for relief of gas and bloating.

From the Research
Recommended Dose of Gas X (Simethicone)
The recommended dose of Gas X (simethicone) for relief of gas and bloating is not explicitly stated in the provided studies. However, the following information can be gathered:
- A study published in 2018 3 administered simethicone orally, 3 times a day, for 20 consecutive days.
- A study published in 1999 4 used simethicone 125 mg, with 2 chewable tablets given initially, followed by 1 tablet after each unformed stool, up to 4 tablets in any 24-hour period.
- A study published in 2020 5 used pinaverium bromide 100 mg plus simethicone 300 mg, given twice a day.
- A study published in 2019 6 and another in 2021 7 used simethicone in combination with polyethylene glycol for bowel preparation, but the exact dose of simethicone is not specified.
Key Findings
- Simethicone has been shown to be effective in reducing bloating and improving bowel preparation effectiveness 6, 7.
- Simethicone has also been shown to be effective in relieving symptoms of functional bloating 3 and irritable bowel syndrome 5.
- The combination of simethicone with other medications, such as loperamide 4 or pinaverium bromide 5, may provide additional benefits in relieving symptoms of gas and bloating.
