Indications & Clinical Uses

Microlax is a rectal laxative that works locally to relieve bowel retention and promote stool passage.

  • Constipation: facilitates softening of stool and stimulates a bowel movement.
  • Hard stools: softens dense fecal material to ease evacuation.
  • Fecal impaction: helps break down impacted stool for removal.

How It Works

  • Microlax acts as an osmotic laxative; sodium citrate and sorbitol draw water into the intestinal lumen, increasing stool liquidity, while sodium lauryl sulfoacetate irritates the rectal mucosa, triggering peristaltic activity and promoting rapid evacuation of the bowels.

Side Effects

Microlax may cause mild to moderate local reactions following administration.

Common Side Effects

  • Mild rectal burning or stinging sensation.
  • Cramping or abdominal discomfort.
  • Urgency to defecate.
  • Watery or loose stool.
  • Minor rectal bleeding.
  • Nausea.

Serious or Rare Side Effects

  • Severe rectal bleeding.
  • Allergic reaction with rash, swelling, or difficulty breathing.
  • Persistent severe abdominal pain.
  • Electrolyte imbalance with prolonged use.
  • Signs of infection at the rectal site.

Precautions & Warnings

Before using Microlax, consider the following safety measures.

  • Allergy Check: Do not use if you are allergic to any listed ingredient.
  • Bowel Obstruction: Avoid if a mechanical obstruction is suspected.
  • Inflammatory Bowel Disease: Use with caution in ulcerative colitis or Crohn's disease.
  • Duration of Use: Limit to short‑term relief; prolonged use may cause dependence.
  • Medical Review: Seek medical advice if symptoms persist beyond 24 hours.
  • Store at room temperature: Keep in the original container, protect from moisture and direct sunlight.

Avoid Interactions

Microlax has limited systemic absorption, but some interactions may still be relevant.

Major Interactions (Avoid)

  • Electrolyte‑altering drugs (e.g., high‑dose diuretics): may exacerbate electrolyte shifts when used together.

Moderate Interactions (Monitor Closely)

  • Oral laxatives: concurrent use can increase risk of diarrhea.
  • Antacids or pH‑altering agents: may affect absorption of other oral medications.
  • Anticoagulants: monitor for increased rectal bleeding.
  • Antibiotics with gastrointestinal side effects: watch for additive irritation.
  • Herbal remedies that affect bowel motility: assess combined effect.

Frequently Asked Questions

Microlax is a rectally administered enema used to relieve occasional constipation, soften hard stools, and assist in the evacuation of fecal impaction. It works locally in the rectum to promote rapid bowel movements without systemic effects.

Sodium citrate acts as an osmotic agent, drawing water into the intestinal lumen. This increase in intraluminal fluid softens the stool and creates a pressure gradient that stimulates peristalsis, facilitating easier passage of feces.

The appropriate dose of Microlax is determined by the prescribing healthcare professional based on the patient’s age, condition severity, and clinical response. Users should follow the prescriber’s instructions and the product label.

Safety data for Microlax in pregnancy and lactation are limited. It should only be used if the potential benefit outweighs any possible risk, and after consultation with a qualified healthcare provider.

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 any necessary import documentation.

Microlax provides rapid, localized relief through an osmotic and irritant mechanism, unlike oral bulk‑forming agents that work systemically. Compared with oral stimulant laxatives, Microlax often produces a quicker bowel movement with fewer systemic side effects.

Store Microlax at room temperature, preferably below 25 °C, in its original packaging. Protect the container from moisture and direct sunlight to maintain product stability.

Microlax is administered rectally. The user lies on their side, inserts the pre‑filled applicator tip into the rectum, gently squeezes the container to deliver the solution, and remains lying down for a few minutes to allow the enema to work.

Serious risks, though rare, include severe rectal bleeding, allergic reactions such as rash or swelling, and electrolyte disturbances with prolonged use. Any signs of these reactions require immediate medical attention.

Microlax should not be used by individuals with known hypersensitivity to its ingredients, those with a confirmed mechanical bowel obstruction, or patients with severe inflammatory bowel disease without medical supervision.
