Used for the relief of occasional constipation. Typically recommended for short-term use only, as prolonged use may lead to dependence or electrolyte imbalances.
Both aloin and phenolphthalein are stimulant laxatives that work by irritating the intestinal lining and increasing water secretion into the colon, which stimulates peristalsis and promotes bowel movements.
Phenolphthalein has been restricted or discontinued in many countries due to carcinogenicity concerns. This medication should not be used long-term. Consult a healthcare provider before use, especially if pregnant, breastfeeding, or having abdominal pain. May cause cramping, diarrhea, or electrolyte disturbances.
