Indications & Clinical Uses

Microlax, a rectal laxative enema, acts on the gastrointestinal tract to relieve constipation and prepare the bowel.

  • Occasional constipation: provides rapid evacuation of stool.
  • Bowel cleansing before diagnostic procedures: clears the colon for procedures such as colonoscopy.
  • Pre‑operative bowel preparation: assists in clearing the bowel prior to surgery.

How It Works

  • Microlax works by creating an osmotic gradient in the colon through sorbitol and sodium citrate, drawing water into the intestinal lumen. Sodium Lauryl Sulfoacetate acts as a surfactant, reducing surface tension and stimulating colonic motility, which together facilitate rapid bowel evacuation.

Side Effects

Common Side Effects

  • Mild abdominal cramping: transient discomfort in the lower abdomen.
  • Rectal irritation: mild burning or itching at the site of administration.
  • Urgency to defecate: a strong sensation to evacuate soon after use.
  • Mild diarrhea: loose stools that resolve quickly.

Serious or Rare Side Effects

  • Severe abdominal pain: intense pain requiring medical attention.
  • Rectal bleeding: presence of blood in stool or after administration.
  • Allergic reaction: rash, swelling, or difficulty breathing indicating hypersensitivity.

Precautions & Warnings

Precautions should be observed before using Microlax.

  • Do not use if you have intestinal obstruction: risk of perforation.
  • Avoid during active inflammatory bowel disease flare: may worsen symptoms.
  • Use with caution in patients with electrolyte disorders: monitor electrolyte levels.
  • Pregnant or breastfeeding women should consult a healthcare professional before use.
  • Children under three years of age should not use without medical advice.
  • Store at room temperature: keep in the original container, protect from moisture and heat.

Avoid Interactions

Microlax may interact with other medications.

Major Interactions (Avoid)

  • Concurrent use of strong stimulant laxatives: may cause severe electrolyte loss.
  • Use with oral rehydration salts containing high sodium: risk of hypernatremia.

Moderate Interactions (Monitor Closely)

  • Diuretics: monitor electrolyte balance.
  • Anticholinergic drugs: may reduce laxative efficacy.
  • Antibiotics affecting gut flora: may alter bowel response.

Frequently Asked Questions

Microlax is an over‑the‑counter rectal enema used to provide rapid relief of occasional constipation and to cleanse the bowel before diagnostic procedures such as colonoscopy or before certain surgeries.

Sorbitol creates an osmotic gradient that draws water into the colon, softening stool and increasing intestinal volume. This, together with the surfactant action of sodium lauryl sulfoacetate, stimulates colonic motility and promotes prompt evacuation.

The appropriate dose of Microlax is determined by the prescribing healthcare professional based on the patient’s age, condition, and clinical needs. The product is supplied as a pre‑measured enema solution for single‑use administration.

Pregnant or breastfeeding individuals should consult their healthcare provider before using Microlax. While the product is generally considered low risk, professional guidance is essential to weigh any potential benefits against possible risks.

To order Microlax, submit an enquiry on the product page at gnhindia.com with the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and necessary import documentation.

Microlax provides a rapid, localized effect via rectal administration, unlike oral osmotic laxatives that act systemically. Its enema form offers quicker relief and is often preferred for bowel preparation before procedures, whereas oral agents may be used for chronic constipation management.

Microlax should be stored at room temperature, away from direct sunlight and moisture. Keep the container tightly closed in its original packaging until use to maintain product stability and efficacy.

Microlax is administered rectally as a single‑use enema. The patient lies on their side, inserts the nozzle gently into the rectum, and releases the solution. The product typically works within minutes, prompting a bowel movement.

Serious risks include severe abdominal pain, rectal bleeding, and allergic reactions such as rash or difficulty breathing. If any of these occur, medical attention should be sought immediately.

Microlax should be avoided by individuals with known intestinal obstruction, active inflammatory bowel disease flare, severe electrolyte imbalance, or those who are allergic to any of its ingredients. Children under three years of age should not use it without medical supervision.
