Milaxulose (Lactulose, Vaseline, Liquid Paraffin)

Milaxulose, an osmotic laxative and stool softener, is used to manage conditions that require softening of stool or reduction of intestinal ammonia.

• Constipation: softens stool and promotes regular bowel movements.
• Hepatic encephalopathy prevention: lowers intestinal ammonia levels to reduce neurotoxicity in liver disease patients.
• Bowel preparation for diagnostic procedures: facilitates complete evacuation of the colon before colonoscopy or imaging.

• Lactulose is metabolized by colonic bacteria into short‑chain fatty acids, creating an osmotic gradient that retains water in the intestinal lumen and softens stool. Vaseline and liquid paraffin coat the mucosal surface, providing lubrication that eases stool passage through the gastrointestinal tract.

Milaxulose may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Abdominal cramping: mild discomfort due to increased bowel activity.
• Flatulence: excess gas production from bacterial fermentation.
• Diarrhea: loose stools when the osmotic effect is pronounced.
• Nausea: occasional feeling of queasiness.
• Bloating: sensation of abdominal fullness.
• Mild rectal irritation: irritation of the anal mucosa.

Serious or Rare Side Effects

• Electrolyte imbalance: significant loss of potassium or sodium.
• Severe dehydration: excessive fluid loss leading to low blood volume.
• Allergic reaction: rash, itching, or swelling of the face, lips, or tongue.
• Severe abdominal pain: intense pain that may indicate obstruction.
• Rectal bleeding: unexpected blood in stool.
• Hypotension: low blood pressure due to fluid shifts.

Before initiating Milaxulose therapy, consider the following safety measures.

• Renal function assessment: evaluate kidney status to avoid accumulation of osmotic agents.
• Electrolyte monitoring: check serum potassium and sodium during prolonged use.
• Diabetes caution: monitor blood glucose as lactulose may affect glycemic control.
• Intestinal obstruction avoidance: do not use in patients with known mechanical blockage.
• Hypersensitivity check: ensure no known allergy to lactulose, Vaseline, or liquid paraffin.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Milaxulose can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Magnesium‑containing antacids: may enhance laxative effect and cause electrolyte disturbances.
• Loop diuretics: increase risk of dehydration and electrolyte loss.
• Insulin or oral hypoglycemics: lactulose may alter glucose absorption, affecting glycemic control.

Moderate Interactions (Monitor Closely)

• Broad‑spectrum antibiotics: may alter gut flora, reducing lactulose metabolism.
• Calcium or iron supplements: can bind lactulose and diminish its efficacy.
• Probiotic preparations: additive effect on bowel motility may increase loose stools.
