Gastrona Tablet

Antacid for quick relief of:

• Heartburn, acid indigestion, sour stomach
• Hyperacidity, gastritis symptoms
• Symptoms of peptic ulcer and reflux (as an add-on)

Adults: 1–2 tablets chewed, or 5–10 ml (1–2 teaspoons) suspension, 3–4 times daily, 30 minutes–1 hour after meals and at bedtime, or when symptoms occur. Do not exceed the maximum on the pack.

Children over 6 years: half the adult dose, as directed.

• Chew tablets well; shake the suspension before use.
• Do not use regularly for more than 2 weeks without medical advice.

• Severe kidney impairment
• Low phosphate levels
• Allergy to the product
• Bowel obstruction, undiagnosed severe abdominal pain

Common: constipation (aluminium) or diarrhoea (magnesium) — usually balanced in the combination; chalky taste.

With long-term high doses: low phosphate (bone weakness), aluminium build-up in kidney failure, high magnesium in kidney failure (weakness, drowsiness).

• Kidney disease: avoid long-term use.
• Persistent heartburn, difficulty swallowing, weight loss, black stools or vomiting blood need medical review.
• Some products contain sugar or sodium.

Occasional use at recommended doses is considered safe in pregnancy and breastfeeding.

Antacids reduce absorption of many medicines — take them 2–4 hours apart from:

• Tetracyclines, quinolones (ciprofloxacin, levofloxacin), azithromycin, cefpodoxime
• Iron, levothyroxine, digoxin, ketoconazole/itraconazole, bisphosphonates, gabapentin, mycophenolate
• Enteric-coated tablets (may dissolve too early)

Diarrhoea or constipation; in kidney failure, high magnesium/aluminium. Seek advice.

Store below 30°C; do not freeze the suspension.
