Hi and thank you so much for this query. I am so sorry to hear about this pain and diarrhea that you have reported. The reason why it is not advised to take these too drugs together is often because of the aggravated constipation that they can cause. However, because you are having diarrhea, it will be okay to take imodium to stop the frequent stools. What is the cause of this diarrhea? if it has not lasted more than 14days and the cause has been shown to be non infectious, i will discourage any use of imodium for it may rather be more harmful than helpful. Remember to drink as much water as possible to stay well hydrated. Thank and hope this helps. I wish you well. Dr. Ivo, C.
