ENTEROSGEL is a safe and drug free treatment with brilliant safety history over 30 years and no reports of adverse events. There are no systemic side effects from taking Enterosgel. Very rare possible side effects are constipation or nausea, which can be also due to the underlining condition (e.g. IBS, stomach or vomiting bugs). It is important to take plenty of fluids during treatment of diarrhoea. During treatment of chronic IBS diarrhoea stop taking ENTEROSGEL if you do not have bowel movement for 1-2 days and increase intake of water and continue the treatment after the next bowel movement.
