<<Disclaimer: Verify this information before applying it to your situation.>> My doctor suggested I take simethicone in the form of GasX. I called the company and they get their starch from outside sources and could not guarantee what it was in there. They said it is not g/f. Is there another chewable brand to use? I tried the Walmart brand Equate gelcap. It is not releasing the simethicone as fast as the chewables and they are g/f. I was also taking Bentyl for the past week. I am getting reactions, hyper feeling, nausea, and I know there is lactose in it. I am allergic to milk protein. I did some research and I found out that the proteins from the milk can be in the lactose and even in such small amts it can affect you if you are sensitive. What do other people do when there is lactose in the drugs you are prescribed. It is hard to find substitutes. Is Stokes the only answer? Thanking you in advance.
