Gas-X, also known as Simethicone, is an over-the-counter (OTC) medication that is commonly used to relieve symptoms of gas, bloating, and discomfort caused by excessive gas in the stomach and intestines. While Gas-X is generally considered safe and effective for most people, it can cause some side effects.

This product generally has no side effects, but nausea, constipation, diarrhea, and headache have been reported. These symptoms are usually mild and typically go away on their own within a few days of starting treatment. If you experience any unusual effects after taking this medicine, contact your doctor or pharmacist right away.

A serious allergic reaction to simethicone is rare. If you notice any symptoms of severe allergy; such as rash, hives, itching/swelling or difficulty breathing, seek medical attention right away.

Can Gas-X Interact With Other Medications?

Gas-X can also interact with some medications, including blood thinners and certain antibiotics. If you're taking other medications, it's important to talk to a healthcare professional before taking Gas-X.

Gas-X is also not recommended for pregnant or breastfeeding women, or for children under the age of 2, without consulting a doctor.
