    Usually Benefiber is well tolerated and does not cause severe reactions. Occasionally, however, Benefiber may cause some side effects, such as intestinal blockage, allergic reaction, cramping, bloating, gas, diarrhea or constipation. If you experience these or any other side effects, call your doctor as soon as you can.
