Activated Dimeticone is chemically inert and is not absorbed. Its effect is local on the intestinal contents.
No side effects from the substance are reported from the literature.
From the toxicity trials undertaken by Dow Corning, it has been demonstrated in the rat that all the Dimeticone was recovered in the faeces and that there was no increase in urinary salicate output.
In four human subjects given 376.5mg of Activated Dimeticone, twice daily for 10 days, it was found that there was no increase in their urinary silicate output and no evidence of absorption of the silicone.
