Gavicid (Sodium Alginate, Sodium Bicarbonate & Calcium Carbonate): Dual-Action Antacid & Reflux Barrier

Gavicid is a specialized antacid and antireflux combination featuring two fast-acting antacids (Calcium Carbonate and Sodium Bicarbonate) paired with an alginate (Sodium Alginate). It works purely via a physical mechanism that does not rely on systemic bloodstream absorption.

Upon ingestion, the solution reacts rapidly with stomach acid to form a neutral, protective "raft" of alginic acid gel that floats on top of the stomach contents. This physical barrier caps the "acid pocket," effectively trapping pepsin and bile and blocking gastro-esophageal reflux for up to 4 hours. If reflux does occur, the soothing gel is pushed into the esophagus first, coating it to prevent painful irritation.

📋 Indications: Rapid Upper GI Relief

Gavicid is indicated to treat the symptoms of:

• Gastric reflux, indigestion, and bloating (flatulence) associated with reflux.

• Heartburn, including heartburn experienced during pregnancy.

• All forms of upper stomach (epigastric) and chest (retrosternal) burning or distress caused by acid backup.

🥄 Dosage and Administration Guidelines

1. Gavicid Oral Suspension

• Adults and Children over 12 years: Take 10 to 20 mL after meals and right before bedtime (up to 4 times a day).

• Children 6 to 12 years: Take 5 to 10 mL after meals and at bedtime (up to 4 times a day).

• Children under 6 years: Not recommended.

2. Gavicid Chewable Tablets

• Crucial Instruction: Tablets must be chewed thoroughly before swallowing.

• Adults and Children 12 years and over: Chew 2 to 4 tablets after meals and at bedtime (up to 4 times a day).

• Children under 12 years: Give only if explicitly advised by a medical professional.

🛑 Crucial Drug Interactions (The 2-Hour Rule)

Because Gavicid creates a physical gel layer and alters stomach acidity, it can severely impair the absorption of other medications. Always separate Gavicid from other drugs by at least 2 hours, especially:

• Antibiotics (Tetracyclines, Fluoroquinolones).

• Heart and blood pressure medications (Digoxin, Beta-blockers like Atenolol, Metoprolol, Propranolol).

• Hormones, Steroids, and Minerals (Thyroid hormones, Glucocorticoids, Iron salts).

• Antifungals (Ketoconazole) and Bone-density medications (Bisphosphonates).

⚠️ Precautions, Warnings & Contraindications

• High Sodium Alert: Every 20 mL contains 254.5 mg of sodium. Patients on a highly restricted salt diet—such as those with congestive heart failure or kidney issues—must exercise strict caution.

• Calcium Content: Each 20 mL contains 260 mg of calcium (75 mg per tablet). Use with caution if you have a history of high blood calcium (hypercalcemia), kidney stones, or calcium deposits in the kidneys.

• Phenylketonuria (PKU): Because Gavicid tablets contain aspartame, they should not be given to patients with phenylketonuria.

• Masking Symptoms: Do not use this medication continuously for more than 7 days. Prolonged use can mask symptoms of a more serious, underlying medical condition. It should not be used by individuals with severe renal insufficiency or low blood phosphate (hypophosphatemia).

🤰 Pregnancy & Lactation

• Pregnancy & Breastfeeding: Extensively documented data from over 500 pregnant women shows no toxic effects on the fetus or newborn. Gavicid is safe to use during pregnancy and breastfeeding if clinically required.

📦 Storage Conditions

• Store below 30°C in a dry place protected from light.

• Do not refrigerate or freeze. Keep out of the reach of children.
