Overview

Dimectal Powder for Oral Suspension 3g is an Over-the-Counter (OTC) gastrointestinal product supplied as an off-white powder in individual 3g sachets, each containing diosmectite (dioctahedral smectite) as the active ingredient. It is sold at DoctorOnCall, a licensed online pharmacy serving customers in Malaysia and Singapore, and is intended for oral use after being mixed with water.

Diosmectite is a naturally derived aluminomagnesium silicate clay compound, and Dimectal belongs to the adsorbent-powder class of gastrointestinal products, distinct from motility-modifying agents and from older kaolin-pectin-based formulations. Each sachet is designed to be dispersed in water to form a suspension immediately before it is taken, rather than swallowed as a dry powder.

Dimectal Powder is formulated for use across a range of age groups, with dosing that differs between adults and children, and is typically packed in boxes of multiple sachets for convenient individual dosing. The product is presented with flavouring agents to improve the palatability of the mixed suspension.

Directions for Use

  • Empty the entire contents of one sachet into approximately half a glass (100ml) of water.
  • Stir well until the powder is evenly and smoothly dispersed, then drink the suspension straight away.
  • Take on an empty stomach or between meals where possible.
  • If other oral medicines are also being taken, separate the timing by at least two hours, as diosmectite can reduce the absorption of other drugs taken at the same time.
  • Do not exceed the number of sachets recommended for your age group in any 24-hour period.

Dosage

Adults and children over 12 years: 1 sachet mixed with water, taken 2 to 3 times daily depending on the severity of symptoms, up to a maximum of 3 sachets in 24 hours unless a doctor advises otherwise. For children aged 2 to 12 years, dosing is age- and weight-dependent and should follow the printed pack insert or the guidance of a doctor or pharmacist rather than a fixed adult schedule. If a dose is missed, take the next sachet at the usual time rather than doubling up. Self-treatment should not continue beyond 2 to 3 days without improvement; if symptoms persist, worsen, or are accompanied by fever, blood in the stool, or signs of dehydration, stop self-treatment and consult a doctor or pharmacist.

Shelf Life

Use before the expiry date printed on the sachet and outer packaging. Do not use if the sachet is torn, punctured, or shows signs of moisture ingress. Once mixed with water, the suspension should be drunk immediately; do not prepare a sachet in advance and store it for later use.

Storage Instructions

Store below 30°C in a cool, dry place, away from direct sunlight and moisture. Keep the sachets in their original box until ready to use, and keep out of reach and sight of children.

Side Effects

  • Constipation
  • Abdominal bloating
  • Nausea (rare)
  • Potential allergic reaction (very rare)

Contraindications

  • Known hypersensitivity to diosmectite or to any excipient in the formulation.
  • Pre-existing severe constipation, reduced bowel motility, or suspected intestinal obstruction.
  • Not recommended in patients with fructose intolerance if a particular formulation contains fructose-based sweeteners, unless confirmed suitable by a pharmacist.

Drug / Food Interactions

  • May reduce the rate and extent of absorption of other oral medicines if taken at the same time; separate dosing from other oral drugs by at least two hours.
  • No specific food interactions are established; the powder is intended to be mixed with water rather than milk, juice, or other beverages.
  • Inform your doctor or pharmacist of all other medicines, supplements, and herbal products you are taking before starting this product.

Quick Tips

  • Check the expiry date on each sachet before use.
  • Mix the full contents of a sachet in water only, not in other beverages, for even dispersion.
  • Keep a simple count of how many sachets have been taken within 24 hours.
  • Store sachets in their original carton to protect them from humidity.
  • Maintain your usual fluid intake, timed separately from this product.
  • Keep the product in a location that is out of reach of young children.

Ingredients / Active Ingredients

  • Active ingredient: Diosmectite (dioctahedral smectite), 3g per sachet.
  • Supplied as a powder for oral suspension, combined with flavouring and sweetening agents to improve palatability once mixed with water.
  • A complete list of inactive excipients should be confirmed against the printed pack insert, as a full excipient breakdown is not independently published for this formulation.
