[|AI|]  Hello.  Welcome to Ask A Doctor.  I have read your query and here is my advice.  A side effect of Motrin(ibuprofen) is to cause stomach inflammation which can make the stomachs inside lining bleed. The blood is carried along with intestinal contents through the entire intestinal tract.  By the time it reaches the end it is black and makes stool black.  Blueberries, Pepto-Bismol, and iron supplements also make stool black.  A hive rash is an allergic rash and could be due to Motrin, especially if the hives appeared very soon after you gave him the dose.  Tylenol does not irritate the stomach and is safer.  Hard stool is usually due to not enough liquid intake.  You may want to try giving apple and pear juices.  If that doesn't help, prune juice, 1-2ounces one-two times per day might be beneficial.  Frequent colds and coughing could be from being in close contact with other young child Chat Doctor.  How old is your child?  Does he attend daycare?  Also, cold and cough syrups are NOT recommended to give to child
