No, suppositories are only glycerine which isn't harmful. But the first thing you need to do is find out why you have to constantly use something to have a BM. You need to rule out any intestinal problems you may have. Until you can see your doctor, try Miralax, it's non-habit forming and over the counter. Check your diet and makes sure you are getting enough fiber, but not too much, and plenty of fluids. Bleeding and an achiness in your lower abdomen at the same time are 2 symptoms of colon cancer, but there are others. See your doctor.
