Indications & Clinical Uses

Microlax, a rectal osmotic laxative, is indicated for conditions affecting bowel motility and stool passage.

  • Constipation: provides rapid softening of stool and promotes evacuation.
  • Occasional bowel irregularity: helps normalize bowel movements.
  • Preparation for diagnostic procedures: facilitates bowel clearance before examinations.

How It Works

  • Microlax works by creating an osmotic gradient in the rectum; sorbitol and sodium citrate draw water into the bowel lumen, while sodium lauryl sulfoacetate stimulates the rectal mucosa. The resulting increase in intraluminal fluid softens stool and triggers peristaltic activity, leading to prompt evacuation.

Side Effects

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

Common Side Effects

  • Mild abdominal cramping.
  • Rectal irritation or burning sensation.
  • Transient urgency to defecate.
  • Mild diarrhea.
  • Nausea.
  • Bloating.

Serious or Rare Side Effects

  • Severe abdominal pain.
  • Rectal bleeding.
  • Allergic reactions such as rash, swelling, or difficulty breathing.
  • Electrolyte imbalance.
  • Severe dehydration.
  • Rectal ulceration.

Precautions & Warnings

When using Microlax, consider the following safety measures.

  • Allergy: Do not use if you are hypersensitive to any of the listed ingredients.
  • Obstruction: Avoid in patients with known intestinal blockage or severe constipation.
  • Inflammatory bowel disease: Use with caution in ulcerative colitis or Crohn's disease.
  • Frequency: Do not exceed the recommended number of applications per day.
  • Child safety: Keep out of reach of children.
  • Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Avoid Interactions

Microlax may interact with other medicines that affect bowel function or electrolyte balance.

Major Interactions (Avoid)

  • Concurrent use of other strong osmotic or stimulant laxatives.
  • High‑dose mineral oil preparations.
  • Medications that require stable electrolyte levels, such as digoxin.

Moderate Interactions (Monitor Closely)

  • Antacids containing magnesium.
  • Certain antibiotics where absorption may be altered.
  • Oral rehydration solutions.
  • Diuretics that influence fluid balance.
  • Antihypertensive agents that could be affected by fluid shifts.

Frequently Asked Questions

Microlax is an over‑the‑counter rectal enema used to relieve constipation and occasional bowel irregularity. It works locally in the rectum to soften stool and stimulate evacuation, providing rapid relief for adults and children.

Sorbitol creates an osmotic gradient that draws water into the rectal lumen. This increase in fluid softens the stool and, together with sodium citrate and sodium lauryl sulfoacetate, stimulates the rectal mucosa to promote a bowel movement.

The dose of Microlax is determined by the prescribing healthcare professional. Typically a single pre‑measured enema is administered rectally, and the prescriber may advise repeat dosing only if necessary and within safe limits.

Safety data for Microlax in pregnancy and lactation are limited. It should only be used if clearly needed and after consulting a healthcare provider, who can weigh potential benefits against any unknown risks.

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, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Microlax is a rectal osmotic laxative, offering rapid, localized action with minimal systemic absorption. Compared with oral stimulant laxatives, it works faster and is useful when oral routes are unsuitable, but it does not provide the same long‑term bowel regulation as bulk‑forming agents.

Store Microlax at ambient temperature, preferably below 25 °C. Keep the container tightly closed, in its original packaging, and protect it from moisture and direct sunlight to maintain product stability.

Microlax is administered rectally. The pre‑filled enema is gently inserted into the rectum, the nozzle is released to allow the solution to flow, and the patient remains lying down for a few minutes to facilitate evacuation.

Serious risks, though rare, include severe abdominal pain, rectal bleeding, allergic reactions such as rash or swelling, electrolyte disturbances, severe dehydration, and rectal ulceration. Any of these symptoms warrant immediate medical attention.

Microlax should not be used by individuals with known hypersensitivity to its ingredients, those with intestinal obstruction, severe inflammatory bowel disease, or any condition where rectal irritation could worsen the clinical picture. Consultation with a healthcare professional is essential.
