Medical uses

File:Simethiconetablets.jpg

Simethicone tablets

Simethicone is used to relieve the symptoms of excessive gas in the gastrointestinal tract, namely bloating, burping, and flatulence.<ref name=USOTClabel>Template:Cite web</ref><ref>Template:Cite web</ref> While there is a lack of conclusive evidence that simethicone is effective for this use,⁣<ref>Template:Cite web</ref><ref name="drugs.com">Template:Cite web</ref>Template:Failed verification studies have shown that it can relieve symptoms of functional dyspepsia<ref>Template:Cite journal</ref> and functional bloating.<ref>Template:Cite journal</ref>

It has not been fully established that simethicone is useful to treat colic in babies,<ref>Template:Cite journal</ref> and it is not recommended for this purpose.<ref name="drugs.com"/> A study in the United Kingdom reported that according to parental perception simethicone helped infant colic in some cases.<ref>Template:Cite journal</ref>

Simethicone can also be used for suspected postoperative abdominal discomfort in infants.<ref>Template:Cite journal</ref>

Side effects

Simethicone does not have any serious side effects.<ref name=":0" /> Two uncommon side effects (occurring in 1 in 100 to 1 in 1,000 patients) are constipation and nausea.<ref>Template:Cite web</ref>

Though poorly documented,<ref>Template:Cite journal</ref> some studies show a possible negative interaction between simethicone and levothyroxine, meaning it can possibly bind levothyroxine in the GI tract and hence reduce its absorption leaving the patient prone to clinical manifestations of hypothyroidism. It is important to mention the long T_1/2 of levothyroxine which makes the phenomenon a matter of at least a week of using levothyroxine with simethicone. To prevent this interaction, simethicone is recommended to be taken at least 4 hours before or after levothyroxine.<ref>Template:Cite journal</ref>

Pharmacology

Simethicone is a non-systemic surfactant which decreases the surface tension of gas bubbles in the GI tract.<ref name=":0">Template:Cite journal</ref> This allows gas bubbles to leave the GI tract as flatulence or belching.<ref name=":0" /> Simethicone does not reduce or prevent the formation of gas.<ref>Template:Cite web</ref> Its effectiveness has been shown in several in vitro studies.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref>

Chemistry

Simethicone is a mixture of dimethicone and silicon dioxide.<ref name="merck-dimethicone"> Template:Cite encyclopedia </ref>
