Special Precautions & Warnings:
Pregnancy and breast-feeding: Senna is POSSIBLY SAFE during pregnancy and breast-feeding when taken by mouth, short-term. It is POSSIBLY UNSAFE when taken by mouth long-term or in high doses. Long-term, frequent use, or use of high doses has been linked to serious side effects including laxative dependence and liver damage.
Although small amounts of senna cross into breast milk, it doesn’t seem to be a problem for nursing babies. As long as the mother uses senna in recommended amounts, senna does not cause changes in the frequency or consistency of babies’ stools.
Electrolyte disturbances, potassium deficiency: Overuse of senna can make these conditions worse.
Dehydration, diarrhea or loose stools: Senna should not be used in people with dehydration, diarrhea, or loose stools. It can make these conditions worse.
Gastrointestinal (GI) conditions: Senna should not be used by people with abdominal pain (either diagnosed or undiagnosed), intestinal blockage, Crohn's disease, ulcerative colitis, appendicitis, stomach inflammation, anal prolapse, or hemorrhoids.
Heart disease: Senna can cause electrolyte disturbances and might make heart disease worse.
