Lattulosio Mylan Generics (Lactulose)

Lactulose is used as an osmotic laxative and ammonia‑lowering agent in disorders of the gastrointestinal tract and liver.

• Constipation: softens stool and promotes regular bowel movements.
• Hepatic encephalopathy: lowers colonic ammonia production, improving mental status in liver disease.
• Hyperammonemia in liver disease: reduces blood ammonia levels to help prevent neurological complications.

• Lactulose is a synthetic disaccharide that is not absorbed in the small intestine. In the colon, bacterial enzymes hydrolyze it to short‑chain acids, increasing osmotic pressure and drawing water into the lumen, which softens stool. The resulting acidic environment promotes conversion of ammonia to ammonium, reducing its absorption and systemic levels.

Lactulose may cause a range of adverse reactions, most of which are related to its laxative action.

Common Side Effects

• Flatulence: increased intestinal gas production.
• Abdominal cramps: mild to moderate discomfort.
• Diarrhea: loose stools, especially at higher doses.
• Nausea: occasional feeling of queasiness.
• Bowel sounds: audible rumbling (borborygmi).
• Electrolyte changes: mild shifts in sodium or potassium.

Serious or Rare Side Effects

• Severe dehydration: excessive fluid loss requiring medical attention.
• Electrolyte disturbances: significant hyponatremia or hypokalemia.
• Allergic reaction: rash, itching, or swelling.
• Severe abdominal pain: may indicate intestinal obstruction.

Lactulose should be used with attention to patient‑specific factors and proper handling.

• Renal function assessment: adjust use in patients with impaired kidneys.
• Electrolyte monitoring: check sodium and potassium levels during prolonged therapy.
• Diabetes caution: monitor blood glucose as lactulose may affect carbohydrate metabolism.
• Discontinuation: avoid abrupt cessation in chronic users to prevent rebound constipation.
• Hepatic impairment: dose may need adjustment in severe liver disease.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Lactulose can interact with other medicines, influencing efficacy or safety.

Major Interactions (Avoid)

• Broad‑spectrum antibiotics: may reduce lactulose’s colonic fermentation.
• Diuretics: increase risk of electrolyte imbalance when combined.
• Insulin or oral hypoglycemics: may alter glucose control.

Moderate Interactions (Monitor Closely)

• Probiotics: may exacerbate gas production.
• Other laxatives: additive laxative effect can cause diarrhea.
• Oral potassium supplements: monitor for hyperkalemia when combined with electrolyte shifts.
