Why is this medication prescribed?

Simethicone is a medication commonly prescribed for the relief of symptoms associated with excessive gas in the gastrointestinal (GI) tract. It is an anti-foaming agent that works by breaking down gas bubbles, making them easier to pass and reducing discomfort caused by gas buildup.

Common reasons why people might use Simethicone include:

  • Gas and bloating: Simethicone helps alleviate the symptoms of excess gas, which can lead to bloating, belching, and discomfort in the abdomen.
  • Flatulence: The medication can be used to reduce excessive gas passed through the rectum (flatulence).
  • Postoperative gas pain: After certain surgeries, patients may experience trapped gas in the digestive system, leading to discomfort and pain. Simethicone can be used to ease this postoperative gas pain.

How should this medicine be used?

  • Dosage: Follow the dosage instructions provided by your healthcare provider or as indicated on the product label. The recommended dosage may vary depending on the specific formulation of simethicone (e.g., chewable tablets, liquid drops, capsules). It’s essential to adhere to the prescribed dose.
  • Timing: Simethicone is usually taken after meals and at bedtime or as directed by your doctor. This timing is designed to coincide with the digestion process, helping to alleviate gas-related symptoms more effectively.
  • Administration: The form of simethicone can vary (tablets, capsules, chewable tablets, or liquid drops). Always take it with water unless otherwise instructed by your healthcare provider.
  • For infants: If using simethicone drops for infants, follow the dosage instructions provided with the product or as prescribed by your pediatrician. The drops can be given directly or mixed with a small amount of water, formula, or breast milk.
  • Precautions: While simethicone is generally safe for most individuals, it’s essential to consult your doctor before using it, especially if you have any underlying health conditions or are taking other medications. Your doctor can advise you on whether simethicone is suitable for you and if any potential drug interactions need to be considered.
  • Do not exceed the recommended dose, as excessive use may not provide additional benefits and could lead to unwanted side effects.If symptoms persist or worsen, or if you experience any unusual or severe side effects, contact your healthcare provider promptly.

Remember, simethicone is a symptomatic relief medication and does not treat the underlying cause of gas-related issues. If you have recurring or persistent digestive problems, it’s important to seek medical evaluation to identify and address the root cause.

Other uses for this medicine

Simethicone is primarily used for relieving gas-related symptoms, as mentioned earlier. It is not intended to treat other medical conditions, and using it for other purposes should be done under the guidance of a healthcare professional.

What special precautions should I follow?

Here are some general guidelines for using antacid products containing simethicone, such as Mylanta:

  • Dosage: Follow the recommended dosage as indicated on the product label. The dosage may vary depending on the specific formulation of Mylanta (e.g., liquid, chewable tablets). Take care not to exceed the maximum daily dose.
  • Timing: Mylanta is typically taken after meals and at bedtime, or as directed by your healthcare provider. The timing is intended to coincide with the occurrence of symptoms, such as indigestion or heartburn.
  • Administration: The product may come in different forms (liquid, tablet, or chewable tablet). Take it with water unless the label or your doctor advises otherwise.
  • Drug interactions: Inform your healthcare provider about any other medications you are taking, as certain drugs may interact with antacids containing simethicone.
  • Precautions: If you are pregnant, nursing, or have any underlying health conditions, consult your healthcare provider before using Mylanta or any other medication.
  • Allergies: If you are allergic to any of the ingredients in Mylanta, avoid using it and seek an alternative treatment option.
  • Storage: Store the product according to the instructions on the label, typically at room temperature and away from moisture and direct sunlight.

It’s essential to use Mylanta or any medication as directed and not to self-diagnose or self-treat without consulting a healthcare professional. If you have any questions or concerns about using Mylanta or any simethicone-containing product, talk to your doctor or pharmacist for personalized guidance and advice.

What special dietary instructions should I follow?

There are no specific dietary instructions that need to be followed for Simethicone. Since Simethicone is an anti-gas medication that acts locally in the gastrointestinal tract to break up gas bubbles, it is not affected by food intake. You can take Simethicone with or without food as directed on the product label or by your healthcare provider.

What should I do if I forget a dose?

If you forget to take a dose of Simethicone, there is generally no need to worry. Simethicone is not a medication that needs to be taken on a strict schedule, and missing a dose is unlikely to cause any significant issues. Since it is primarily used for symptom relief, you can take the missed dose whenever you remember, provided it is not too close to the time for your next scheduled dose.

What side effects can this medication cause?

If you meant “Mylanta,” which is an antacid product containing simethicone along with aluminum hydroxide and magnesium hydroxide, it’s important to understand the potential side effects associated with the individual components.

Common side effects of simethicone, when used in antacid products like Mylanta, are generally mild and may include:

  • Nausea: Some individuals may experience mild nausea.
  • Diarrhea: In rare cases, simethicone may cause loose stools or diarrhea.

Side effects related to aluminum hydroxide and magnesium hydroxide (the antacid components of Mylanta) may include:

  • Constipation: Aluminum hydroxide may cause constipation in some individuals.
  • Diarrhea: Magnesium hydroxide can have a laxative effect and may lead to diarrhea.
  • Calcium depletion: Prolonged and excessive use of aluminum-containing antacids may lead to calcium depletion in the body.
  • Electrolyte imbalances: Magnesium-containing antacids can cause electrolyte imbalances if used excessively.
  • Kidney function: Prolonged use of aluminum-containing antacids may affect kidney function in some individuals.

It’s important to note that not everyone will experience side effects, and most people can use Mylanta or similar antacids containing simethicone without any issues. However, if you have any concerns about using Mylanta or experience unexpected or severe side effects, it’s crucial to seek medical advice promptly.

Always use medications, including over-the-counter products, according to the recommended dosage and follow the instructions on the product label or as directed by your healthcare provider. If you have specific questions about the side effects of Mylanta or any other medication, consult your doctor or pharmacist for personalized information and guidance.

What should I know about storage and disposal of this medication?


  • Store Simethicone products at room temperature, away from moisture, heat, and direct sunlight.
  • Keep the medication out of reach of children and pets to prevent accidental ingestion.
  • Follow any specific storage instructions provided on the product label.

In case of emergency/overdose

  • In case of an emergency, such as a severe allergic reaction (difficulty breathing, hives, swelling) or any other serious side effects, seek immediate medical attention or call your local emergency number.
  • Overdosing on Simethicone is unlikely due to its low systemic absorption and generally mild effects. However, if you suspect an overdose or accidental ingestion of large quantities, contact your local poison control center or seek medical attention promptly.
