Importal Unidose (Lactitol Monohydrate)

Importal Unidose (lactitol) is used within the gastrointestinal therapeutic area to manage bowel motility disorders.

• Constipation: softens stool and promotes regular bowel movements.
• Chronic constipation: provides ongoing relief for patients with long‑term difficulty evacuating.
• Functional constipation: improves symptoms in individuals with constipation without an identifiable organic cause.

• Lactitol monohydrate is a non‑absorbable sugar alcohol that remains in the intestinal lumen, where it increases osmotic pressure. This draws water into the bowel, softening the fecal mass and stimulating peristaltic activity, thereby facilitating stool passage without significant systemic absorption.

Lactitol is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Abdominal bloating: sensation of fullness or swelling in the abdomen.
• Flatulence: increased intestinal gas.
• Mild diarrhea: loose stools occurring with higher doses.
• Nausea: feeling of queasiness.
• Abdominal cramps: intermittent painful contractions.

Serious or Rare Side Effects

• Severe dehydration: excessive fluid loss requiring medical attention.
• Electrolyte imbalance: abnormal levels of sodium, potassium, or other ions.
• Allergic reaction: rash, itching, swelling, or difficulty breathing.
• Severe abdominal pain: persistent or worsening pain.
• Persistent vomiting: inability to retain oral intake.

Before using Importal Unidose, consider the following safety measures.

• Renal function assessment: evaluate kidney health, as reduced clearance may affect fluid balance.
• Fluid intake monitoring: ensure adequate hydration to prevent dehydration.
• Diabetes caution: lactitol is a sugar alcohol; monitor blood glucose in diabetic patients.
• Intestinal obstruction avoidance: do not use if a blockage is suspected.
• Dose limitation: do not exceed the prescriber's recommended amount.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Lactitol may interact with other medicines, requiring attention to potential effects.

Major Interactions (Avoid)

• Other osmotic laxatives: concurrent use can cause excessive fluid loss.
• Antidiabetic agents: may alter glucose control, requiring dose adjustment.
• Electrolyte‑depleting drugs (e.g., loop diuretics): increase risk of electrolyte disturbances.

Moderate Interactions (Monitor Closely)

• Mineral supplements (e.g., calcium, magnesium): may reduce lactitol absorption.
• Iron preparations: concurrent intake can diminish iron uptake.
• Antibiotics (e.g., tetracyclines): altered gut flora may affect drug efficacy.
