Hovid Mixture Magnesium Trisilicate

Hovid Mixture Magnesium Trisilicate is an oral antacid mixture manufactured by Hovid Berhad, a Malaysian pharmaceutical company. Each 100ml of the sugar-free liquid contains Magnesium Trisilicate 3.33% w/v, Light Magnesium Carbonate 3.33% w/v, and Sodium Bicarbonate 3.33% w/v as the active ingredients, registered with the Malaysian National Pharmaceutical Regulatory Agency under registration number MAL15015109X.

As an OTC product, this mixture is sold in pharmacies across Malaysia without requiring a doctor’s prescription. It is supplied as a 120ml bottle and is formulated as a sugar-free, ready-to-use liquid, distinguishing it from tablet-form antacid products that need to be chewed or dissolved. The manufacturer’s own product listing notes it is intended for use in individuals aged 6 years and above.

Hovid Berhad is a long-established Malaysian pharmaceutical manufacturer with a wide portfolio of alimentary tract and gastrointestinal products. This mixture follows a compound magnesium trisilicate formula that has long been used in antacid mixtures, combining three separate active ingredients in one liquid dosage form rather than relying on a single agent.

Shake the bottle well before each use, as the active ingredients can settle at the bottom of the liquid over time.

Measure the dose using a standard 5ml medicine spoon or the measuring cup provided, rather than an ordinary kitchen spoon, to ensure an accurate amount is taken.

This product is typically taken after meals and at bedtime, as directed on the pack label or by a healthcare professional.

Leave a gap of at least 2 hours between taking this mixture and any other oral medicine, as it may affect how well other medicines are absorbed.

For adults and children aged 6 years and above, the typical dose is 2 to 3 teaspoons (approximately 10ml to 15ml) taken 3 to 4 times daily, generally after meals and at bedtime, or as directed by a healthcare professional.

Do not exceed a total of 45ml in any 24-hour period. This product is not intended for use in children under 6 years of age unless specifically directed by a doctor or pharmacist. If symptoms do not improve after 14 days of regular use, or if they worsen, stop self-treating and consult a doctor or pharmacist, as persistent symptoms may need further medical assessment.

Use before the expiry date printed on the bottle and outer carton.

Once opened, refer to the package insert for guidance on how long the mixture remains suitable for use, and discard any liquid that has developed an unusual smell, colour, or separation that does not re-mix on shaking.

Store below 25°C, away from direct light and moisture.

Keep the bottle tightly closed after use, and store it out of the reach and sight of children.

• Known hypersensitivity or allergy to magnesium trisilicate, magnesium carbonate, sodium bicarbonate, or any other ingredient in this formulation.
• Severe kidney impairment, due to the risk of magnesium or electrolyte accumulation with regular use.
• A low-sodium diet may need to be discussed with a doctor before regular use, as this mixture contains sodium bicarbonate.

• May reduce the absorption of certain other oral medicines, including some antibiotics (such as tetracyclines and certain fluoroquinolones) and iron supplements, if taken at the same time — separate dosing by at least 2 hours.
• May alter the absorption of some other prescription medicines that depend on stomach acidity; check with a doctor or pharmacist if you are taking other regular medicines.
• Regular use alongside other antacids or medicines containing magnesium, aluminium, or calcium should be discussed with a pharmacist to avoid excessive total mineral intake.
• No specific food interactions are known; this product is typically taken after meals.

• Shake the bottle thoroughly before every dose.
• Use a proper measuring spoon or cup rather than guessing the volume.
• Take other oral medicines at least 2 hours apart from this mixture.
• Do not use continuously beyond 14 days without checking in with a doctor or pharmacist.
• Keep track of how often you are dosing to avoid exceeding the 45ml daily limit.
• Store the bottle upright with the cap fully closed between uses.

Precautions: This mixture contains sodium bicarbonate, so individuals on a doctor-directed low-sodium or low-salt diet, such as those with certain heart or kidney conditions, should check with a doctor before regular use. It also contains magnesium salts, so caution is advised in people with kidney impairment, who may not clear excess magnesium efficiently. Always leave a gap of at least 2 hours between this mixture and any other oral medicine.

When to See a Doctor or Pharmacist: Seek medical advice if symptoms persist beyond 14 days of regular use, if symptoms worsen, if you notice black or tarry stools or vomit that looks like coffee grounds, or if you experience unusual muscle weakness, irregular heartbeat, or signs of an allergic reaction such as facial swelling or difficulty breathing.
