Treatment of occasional constipation and bowel preparation before medical procedures such as colonoscopies or surgeries. The combination aims to provide comprehensive constipation relief.
Agar absorbs water in the intestines to add bulk and stimulate natural contractions; mineral oil coats and softens stool to ease passage; phenolphthalein stimulates intestinal contractions to promote bowel movement.
Phenolphthalein has been removed from the market in many countries due to carcinogenicity concerns. This medication should not be used long-term. Patients should consult healthcare providers before use, especially those with bowel obstructions, kidney problems, or who are pregnant. Do not take within 2 hours of other medications as absorption may be affected.
