What is Lactulose?

Lactulose, the active ingredient in Laevolac, is an osmotic laxative presented as an oral solution for oral use. It is employed to relieve constipation and to reduce ammonia levels in patients with hepatic encephalopathy, particularly in adult and pediatric populations where indicated.

GNH USA supplies Laevolac as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation for global distribution. Customers benefit from reliable lead times and dedicated technical support throughout the procurement process.

What is Lactulose used for?

Laevolac (lactulose) is used in the gastrointestinal and hepatic pathways to manage specific conditions.

Constipation: alleviates hard stools and promotes regular bowel movements. Hepatic encephalopathy: lowers blood ammonia by enhancing colonic excretion, helping to improve mental status.

What are the side effects of Lactulose?

Lactulose may cause a range of adverse reactions, most of which are related to its osmotic activity in the gut.

Common Side Effects: - Bloating: sensation of abdominal fullness. - Diarrhea: loose stools, especially at higher doses. - Nausea: feeling of sickness.

Serious or Rare Side Effects: - Electrolyte imbalance: loss of potassium or sodium causing weakness. - Severe dehydration: excessive fluid loss leading to dizziness or low blood pressure. - Allergic reaction: rash, itching or swelling indicating hypersensitivity.

What precautions apply to Lactulose?

When prescribing Laevolac, clinicians should consider several precautionary measures to ensure safe use. - Dose titration: start with the lowest effective dose and adjust based on response. - Fluid intake: maintain adequate hydration to reduce risk of dehydration. - Renal impairment: monitor kidney function, as reduced clearance may increase osmotic load. - Diabetes mellitus: monitor blood glucose, as lactulose may affect carbohydrate metabolism. - Pediatric use: use under pediatric specialist guidance, adjusting dose for age and weight. - Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture and light.

What does Lactulose interact with?

Lactulose can interact with other medicines, altering their effectiveness or safety profile.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: may reduce lactulose’s osmotic effect. - Antibiotics (e.g., rifaximin): concurrent use may alter gut flora and affect ammonia reduction.

Moderate Interactions (Monitor Closely): - Diuretics: increased risk of electrolyte disturbances. - Insulin or oral hypoglycemics: monitor blood glucose as lactulose can affect carbohydrate absorption. - Oral potassium supplements: may be affected by changes in intestinal pH.

Frequently asked questions

What is Laevolac used for?+
Laevolac contains lactulose, an osmotic laxative indicated for the treatment of constipation and for reducing blood ammonia levels in patients with hepatic encephalopathy. It works by drawing water into the colon to soften stools and by converting ammonia to ammonium, facilitating its excretion. The medication is administered orally and is prescribed by healthcare professionals based on individual patient needs.
How does lactulose work?+
Lactulose is a synthetic disaccharide that reaches the colon unchanged. Colonic bacteria hydrolyze it to short‑chain fatty acids, which increase the osmotic pressure in the lumen, pulling water into the bowel and softening stool. The acidic environment also converts ammonia (NH3) to ammonium (NH4+), reducing its absorption into the bloodstream and helping to lower systemic ammonia levels.
What is the usual dose of Laevolac?+
The appropriate dose of Laevolac is determined by the prescribing clinician based on the indication, patient age, weight, and response to therapy. For constipation, the dose is typically started low and titrated upward until regular bowel movements are achieved. For hepatic encephalopathy, dosing aims to produce two to three soft stools per day. Exact dosing instructions should be obtained from a qualified healthcare provider.
Is Laevolac safe during pregnancy or breastfeeding?+
Lactulose is classified as a Category B medication in many jurisdictions, indicating no proven risk in animal studies but limited human data. It is generally considered safe for use during pregnancy and lactation when clearly needed, as it is poorly absorbed and acts locally in the gut. Nevertheless, pregnant or nursing patients should discuss potential benefits and risks with their obstetrician or physician before starting therapy.
How do I order Laevolac from GNH USA?+
To place an order, visit the product page for Laevolac on the GNH USA website (gnh-usa.com) and submit an enquiry with the required quantity. GNH USA supplies hospitals, pharmacies and procurement teams across international markets. After submission, the sales team will verify trade or institutional credentials, then provide pricing, availability, shipping details and any necessary import documentation.
How does Laevolac compare with other laxatives?+
Compared with stimulant laxatives such as bisacodyl, lactulose works by an osmotic mechanism rather than stimulating intestinal muscle contractions, resulting in a gentler onset of action and fewer cramping side effects. Unlike bulk‑forming agents, lactulose does not require high fiber intake. In hepatic encephalopathy, lactulose is the preferred agent because of its ability to lower ammonia, a benefit not shared by most other laxatives.
What are the storage and handling requirements for Laevolac?+
Laevolac should be stored at ambient temperature, preferably below 25 °C, in its original container to protect it from moisture and light. Ensure the bottle is tightly closed after each use. Do not freeze the product, and keep it out of reach of children. If the solution appears discolored or contains particles, discard it and obtain a new supply.
How is Laevolac administered?+
Laevolac is taken orally, usually as a liquid solution. The dose is measured with a calibrated spoon or cup provided by the manufacturer. It can be taken with or without food, and patients are advised to follow the prescriber’s instructions regarding timing and volume. Adequate fluid intake should be maintained throughout treatment to support its osmotic action.
What are the most serious risks associated with Laevolac?+
The most serious adverse events include severe dehydration, electrolyte disturbances such as hypokalemia, and rare cases of colonic pseudo‑obstruction (Ogilvie’s syndrome). Allergic reactions presenting as rash, itching, or swelling may also occur. Patients should seek immediate medical attention if they experience dizziness, fainting, rapid heartbeat, or signs of an allergic response while using Laevolac.
Who should not use Laevolac?+
Laevolac is contraindicated in individuals with known hypersensitivity to lactulose or any component of the formulation. It should be used with caution, or avoided, in patients with intestinal obstruction, perforation, or severe inflammatory bowel disease. Patients with uncontrolled diabetes or significant renal impairment should be evaluated carefully before initiating therapy, and the decision should be guided by a qualified healthcare professional.
