HalfLytely and Bisacodyl, they may have an increased risk for electrolyte problems. If this laxative causes an electrolyte imbalance, it could increase the risk for certain rare but serious side effects, such as
seizures or heart rhythm problems.
If you have kidney disease, it is important to stay hydrated while using HalfLytely and Bisacodyl. You may also need certain blood tests before and after your colonoscopy.
