I took two stool softener dulculax after the stomach flu because i was constipated 3 days. the duculax gave me cramps and diarrhea. duration?

Constipation: If you experienced a lot of diarrhea as part of the viral intestinal tract infection, it would not be unusual to skip bowel movements for a few days after such complete emptying of intestinal contents. Dulcolax is a potent laxative and can cause cramps. If you're having diarrhea, try to avoid taking meds to stop it. Instead avoid roughage in the diet;only drink room temperature fluids.?See MD

Dulcolax: Cramps and diarrhea are common side effects of Dulcolax, and stopping the medication is the best bet. The medication should be gone from your body over a 2-day timeframe, so the effects will likely go away over that time.
