What is Flatulex for?: Uses, Side Effects, and Safety

4 min read

According to the National Institutes of Health (NIH), Simethicone was FDA-approved in 1952 for managing flatulence and bloating. Flatulex, a medication containing the active ingredient simethicone, is used to provide relief from painful symptoms caused by excess gas in the stomach and intestines.

Quick Summary

Flatulex, featuring the active ingredient simethicone, is a defoaming agent that relieves symptoms of excess gas in the digestive tract, such as bloating, pressure, and discomfort. It works by changing the surface tension of gas bubbles, causing them to combine and pass more easily. The medication is available over-the-counter for both adults and infants.

Key Points

  • Relieves Gas and Bloating: Flatulex is primarily used to treat and relieve the discomfort caused by excess gas, bloating, and abdominal pressure.

  • Contains Simethicone: The active ingredient in Flatulex is simethicone, a non-systemic surfactant that works by breaking down gas bubbles.

  • Breaks Down Gas Bubbles: The medication reduces the surface tension of gas bubbles in the gastrointestinal tract, allowing them to coalesce and pass more easily.

  • Generally Safe: Due to its non-absorbent nature, Flatulex is well-tolerated with few side effects and is considered safe for use in both adults and infants.

  • Aids Medical Imaging: It can be prescribed before an abdominal X-ray or ultrasound to prevent gas interference and ensure clearer imaging.

  • Usage Varies by Age: The appropriate usage of Flatulex depends on the patient's age, weight, and the specific formulation (e.g., drops for infants, capsules for adults). Always follow product instructions or consult a healthcare provider.

  • Can Interact with Thyroid Medicine: A significant drug interaction exists with thyroid medications, which should be taken at least 4 hours apart from simethicone.

  • Not for Underlying Conditions: Flatulex does not treat the underlying cause of gas, such as lactose intolerance or a serious GI condition, but rather the symptoms.

Understanding the Mechanism of Flatulex

Flatulex utilizes simethicone, a silicone compound, as its active ingredient. Simethicone functions as a defoaming agent, physically altering the surface tension of gas bubbles within the digestive tract. This action causes smaller gas bubbles, often trapped in foam or mucus, to merge into larger ones, making them easier to expel through belching or passing gas. Since simethicone is not absorbed into the bloodstream, it has a favorable safety profile for various age groups, including infants.

What is Flatulex For? The Primary Uses

Treating Flatulence and Bloating

The main use of Flatulex is to alleviate the symptoms associated with excess gas, including pressure, bloating, a feeling of fullness, and abdominal discomfort. Gas buildup can result from swallowing air or consuming certain foods. Flatulex helps the body more effectively eliminate this trapped gas, providing rapid relief.

Preparing for Medical Procedures

Flatulex may be used prior to abdominal X-rays or ultrasounds to reduce gas that could obscure imaging and interfere with diagnosis.

Pediatric Use for Infant Colic

Flatulex drops are often used for gas in babies and young children, sometimes referred to as infantile colic. While studies on its effectiveness for colic are mixed, it can help relieve general gas-related discomfort, and age-appropriate doses are considered safe for infants.

Side Effects and Safety Considerations

Simethicone in Flatulex has a high safety profile with a low risk of side effects as it is not absorbed systemically.

Common and Minor Side Effects

Though uncommon, some minor and temporary gastrointestinal issues may occur. These can include mild diarrhea, nausea, or temporary stomach discomfort.

Severe but Rare Allergic Reactions

Very rarely, a severe allergic reaction can occur. Seek immediate medical help if you experience a rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, or difficulty breathing.

Drug Interactions

Simethicone can reduce the absorption of thyroid medications like levothyroxine. To prevent this interaction, take thyroid medication at least 4 hours before or after taking a simethicone product.
