Rationale: When educating a patient taking sennosides, it is important to emphasize that these laxatives should be used for short-term therapy only. The medication does not address hypothyroidism, so this information is not relevant. Patients should be informed that the color of their urine may change to various colors like pink, red, violet, yellow, or brown, which is a common side effect of sennosides. It is advisable to incorporate other forms of bowel regulation alongside sennosides for optimal bowel health.
