Neutricid (Aluminium Oxide, Hydrated, Aluminium Phosphate, Hydrated, Guar, Magnesium Hydroxide)

Neutricid is an antacid that acts on excess gastric acid to alleviate common acid‑related gastrointestinal conditions.

• Heartburn: neutralizes gastric acid to provide prompt relief of the burning sensation behind the breastbone.
• Acid indigestion: reduces post‑prandial discomfort, fullness and burning by raising gastric pH after meals.
• Gastroesophageal reflux: diminishes the frequency and severity of acid reflux episodes, easing throat irritation and chest discomfort.
• Upper abdominal discomfort: alleviates mild pain associated with excess acidity.

• Neutricid works by a chemical neutralization reaction in the stomach. The aluminium oxide, hydrated aluminium phosphate and magnesium hydroxide components each react with hydrogen ions (H⁺) to form water and neutral salts, thereby raising the gastric pH. This reduction in acidity diminishes irritation of the gastric and esophageal mucosa, providing symptomatic relief of acid‑related discomfort. The reaction occurs rapidly upon contact with gastric fluid, allowing prompt pH correction.

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

Common Side Effects

• Constipation: occasional hard stools or reduced bowel movements.
• Diarrhea: loose stools, especially with higher magnesium content.
• Nausea: mild feeling of queasiness after ingestion.
• Abdominal bloating: sensation of fullness or gas in the stomach.
• Flatulence: increased gas production.
• Metallic taste: temporary after‑taste following dosing.

Serious or Rare Side Effects

• Hypermagnesemia: elevated magnesium levels, potentially causing muscle weakness or cardiac effects.
• Metabolic alkalosis: excessive rise in blood pH leading to confusion or tremors.
• Allergic reaction: rash, itching, swelling or difficulty breathing.
• Renal impairment worsening: accumulation of aluminium or magnesium in patients with kidney dysfunction.

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

• Assess renal function: patients with kidney disease may retain aluminium or magnesium.
• Monitor electrolyte balance: prolonged use can affect calcium, phosphate or magnesium levels.
• Limit duration: avoid continuous use beyond the recommended period without medical review.
• Avoid concurrent antacids: combining multiple acid‑neutralizing agents may cause excessive alkalinity.
• Pregnancy and lactation: use only if clearly needed and advised by a healthcare professional.
• Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture and direct sunlight.

Neutricid can interact with other medicines; awareness of these interactions helps prevent reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Tetracycline antibiotics: antacids may impair absorption, reducing antibiotic effectiveness.
• Fluoroquinolone antibiotics: concurrent use can decrease fluoroquinolone bioavailability.

Moderate Interactions (Monitor Closely)

• Iron supplements: antacids may lower iron absorption; separate dosing by at least two hours.
• Levothyroxine: antacid may reduce thyroid hormone absorption; monitor thyroid function tests.
• Warfarin: magnesium may potentiate anticoagulant effect; check INR more frequently.
• Digoxin: altered gastric pH can affect digoxin absorption; monitor serum levels.
