Indications & Clinical Uses

Microlax is an osmotic laxative used to treat conditions affecting bowel motility and stool passage.

  • Constipation: facilitates rapid evacuation of hard stools and relieves abdominal discomfort.
  • Occasional bowel irregularities: normalizes irregular bowel movements by softening stool and stimulating peristalsis.
  • Fecal impaction: helps break down impacted stool and promotes clearance from the rectum.

How It Works

  • Microlax works by delivering a solution containing sorbitol, sodium citrate and sodium lauryl sulfoacetate directly into the rectum. Sorbitol creates an osmotic gradient that draws water into the colon, while sodium citrate further increases fluid retention. Sodium lauryl sulfoacetate acts as a surfactant that irritates the mucosa, stimulating intestinal peristalsis and facilitating bowel evacuation. The combined action results in softened stool and a prompt urge to defecate.

Side Effects

Microlax may cause several adverse reactions, most of which are mild and transient.

Common Side Effects

  • Abdominal cramping: mild discomfort in the lower abdomen.
  • Rectal irritation: burning or stinging sensation at the site of administration.
  • Diarrhea: loose stools occurring shortly after use.
  • Nausea: feeling of sickness without vomiting.
  • Flatulence: increased gas production.

Serious or Rare Side Effects

  • Severe rectal bleeding: unexpected bleeding from the rectum.
  • Allergic reaction: rash, itching, swelling, or difficulty breathing.
  • Electrolyte imbalance: abnormal sodium or citrate levels with excessive use.

Precautions & Warnings

Before using Microlax, consider the following precautions to ensure safe and effective use.

  • Contraindication: avoid if there is rectal hemorrhage, severe inflammatory bowel disease, or recent rectal surgery.
  • Allergy: do not use if you are hypersensitive to sorbitol, sodium citrate, or sodium lauryl sulfoacetate.
  • Frequency: limit use to occasional relief; prolonged daily use may lead to dependence.
  • Pediatric use: consult a healthcare professional before administering to children under 3 years.
  • Pregnancy and lactation: discuss with a physician as safety data are limited.
  • Store at ambient temperature: keep the product below 25 °C, in the original container, protected from moisture and direct sunlight.

Avoid Interactions

Microlax can interact with certain medications or conditions; be aware of the following.

Major Interactions (Avoid)

  • Antidiarrheal agents: concurrent use may reduce the efficacy of Microlax.
  • Oral electrolyte supplements: may alter the osmotic balance and affect stool consistency.

Moderate Interactions (Monitor Closely)

  • Laxatives containing magnesium: combined effect may cause excessive fluid loss.
  • Medications affecting intestinal motility (e.g., opioids): may require dosage adjustment.
  • Chronic kidney disease: monitor electrolyte status when using osmotic agents.

Frequently Asked Questions

Microlax is an over‑the‑counter rectal enema indicated for the rapid relief of constipation, occasional bowel irregularities, and fecal impaction. It works locally in the rectum to soften stool and stimulate a bowel movement, making it useful for adults and children who need prompt evacuation.

The formulation contains sorbitol, sodium citrate and sodium lauryl sulfoacetate. Sorbitol creates an osmotic gradient that draws water into the colon, sodium citrate enhances fluid retention, and sodium lauryl sulfoacetate acts as a surfactant that irritates the rectal mucosa, triggering peristalsis and facilitating stool passage.

The appropriate dose of Microlax is determined by a healthcare professional based on the patient’s age, condition and response. Typically a single enema is administered, and the prescriber may advise repeat dosing only if necessary and after a suitable interval.

Safety data for Microlax in pregnancy and lactation are limited. Women who are pregnant or breastfeeding should discuss use with their physician, who will weigh the potential benefits against any possible risks before recommending the product.

To order Microlax, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request verification of trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Compared with oral laxatives, Microlax provides a faster, localized effect because it is delivered directly to the rectum. It avoids systemic absorption and is useful when rapid relief is needed or when oral agents are poorly tolerated. However, it is intended for occasional use rather than chronic management.

Store Microlax at ambient temperature below 25 °C, in its original packaging, protected from moisture and direct sunlight. Keep the container tightly closed when not in use and out of reach of children.

Microlax is administered rectally. The patient lies on their side, bends the knees toward the chest, and gently inserts the pre‑filled applicator into the rectum. The solution is then released, and the patient remains in position for a few minutes to allow the enema to work before attempting a bowel movement.

Serious risks, although rare, include severe rectal bleeding and allergic reactions such as rash, swelling or difficulty breathing. Excessive use may also lead to electrolyte imbalance. Users should seek immediate medical attention if any of these symptoms occur.

Microlax should be avoided in individuals with active rectal hemorrhage, severe inflammatory bowel disease, recent rectal surgery, or known hypersensitivity to any of its ingredients. It is also contraindicated for patients for whom an osmotic enema is medically inappropriate.
