Duphalac (lactulose) is very safe and gentle, making it suitable for long-term use under a doctor's guidance because it is not habit-forming. It works by drawing water into your bowel to soften your stool. This is incredibly important for helping that painful tear (anal fissure) heal, as softer stools prevent further irritation. While lactulose can be used safely for several weeks or even months to manage chronic constipation and aid healing, it is best to consult your healthcare provider.
