What is simethicone, and how does it work (mechanism of action)?
Simethicone is an anti-gas (anti-flatulence) medication. It acts in the stomach and intestines to change the surface tension of gas bubbles, enabling their breakdown and the formation of larger bubbles. In this way it is believed that gas can be eliminated more easily by belching or passing flatus. Simethicone was approved by the FDA in 1952.
What are the uses for simethicone?
What are the side effects of simethicone?

Treatment options include medicine including, local anesthetics, for example, lidocaine (Xylocaine), pramoxine (Fleet Pain-Relief), and benzocaine (Lanacane Maximum Strength), vasoconstrictors, for example, phenylephrine 0.25% (Medicone Suppository, Preparation H, Rectocaine), protectants, for example, glycerin, kaolin, lanolin, mineral oil (Balneol), astringents, for example, witch hazel and calamine, antiseptics, for example, boric acid and phenol, aeratolytics, for example, resorcinol, analgesics, for example, camphor and juniper tar, and
Gas (intestinal gas) means different things to different people. Everyone has gas and eliminates it by belching, burping, or farting (flatulence). Bloating or abdominal distension is a subjective feeling that the stomach is larger or fuller than normal. Belching or burping occurs when gas is expelled from the stomach out through the mouth. Flatulence or farting occurs when intestinal gas is passed from the anus.
Causes of belching or burping include drinking too rapidly, anxiety, carbonated drinks, habit, and swallowing air.
Causes of bloating or distension include tumors, ascites, fluid within the gastrointestinal (GI) tract, and obesity.
Causes of gas or flatulence are diseases such as sugary foods and drinks, fruits and vegetables, starches (wheat, oats, corn, and potatoes), lactose intolerance, untreated celiac disease, and SIBO.
Treatment for excessive intestinal gas depends on the cause. If anal itching persists, a doctor examination may be needed to identify an underlying cause.
Why Am I So Bloated
Bloating is a feeling that your abdomen is distended or larger than normal, but it does not necessarily mean that it is. Gas (flatulence) also can be a problem if you are bloated. Common, less serious causes of bloating are eating too fast, too much, or too many fatty foods; swallowing air; pregnancy; and menstruation. Cancer and IBD (ulcerative colitis and Crohn's disease) are examples the more serious causes of bloating.
Examples of foods and drinks that cause bloating are:
- High fiber foods if you don't eat them regularly. Eventually the bloating and gassiness will resolve if you eat them on a regular basis.
- Fatty greasy foods
- Dairy products, for example, cheese, ice cream, milk, and yogurt.
- Foods high in salt, for example, processed, frozen, and canned foods.
- Artificial sweeteners
Some doctors and other health care professionals recommend natural remedies like chamomile or peppermint tea, or pumpkin to relieve bloating. Examples of OTC medicine (medicine available without a prescription) and other products that may relieve bloating and gassiness are, Gas-X, Beano, Pepto Bismol, Metamucil, probiotics, and Ex-Lax for constipation associated with bloating. If you have persistent or severe gas and bloating accompanied by any of these symptoms see a doctor or other health care professional.
