I have taken pepcid complete for over 10 years one or two tablets a day depending on usually what i have eaten. spicy mexican ,food italian food ,fried foods really set the acid reflux off. One pepcid complete chewable tablet takes care of the reflux usually for about 24hrs. This was a great product but in south east New Mexico and west Texas it cant be found anymore so i dont know what has happened to it but for at least 4 months now its not been available here. As for as i know i have had no side affects from the use of pepcid complete so i considered it a great product.
