Hi and welcome. Well, side effects for Docusate sodium are generally rare and usually include just mild stomach pain, diarrhea, or cramping Irritated throat (with liquid or syrup forms) may also occur. Serious allergic reactions or side effects are less common and should not worry you. This is a good option for constipation as an alternative for laxatives and magnesium but it may not be beneficial for some people so you dont need to expect some miracle results. It should also be associated with proper diet, fibre rich food, plenty of fluids and fruits. Only on this way some long term results can be expected. I hope I have answered you query. If you have any further questions you can contact us in every time.
