The general recommended dose for Rennie tablets for adults and children over 12 years is to take 2 tablets to be sucked or chewed as a single dose, preferably 1 hour after meals and before bedtime. For heartburn, an extra 2 tablets may be taken between these times. However, the maximum daily limit is usually 10 tablets per day to avoid exceeding 8g of calcium carbonate.

For Rennie Dual Action tablets specifically, the maximum recommended dose is 12 tablets in 24 hours.

If symptoms persist after 14 days of use, it is advised to consult a doctor. Rennie tablets are not recommended for children under 12 years.

In summary:

• Typical dose: 2 tablets after meals and before bed
• Extra 2 tablets for heartburn between doses if needed
• Maximum daily dose: 10 tablets (Rennie Peppermint) or 12 tablets (Rennie Dual Action)
• Not for under 12 years old
• Consult a doctor if symptoms persist beyond 14 days

This guidance helps prevent overdosing and the risk of side effects associated with excessive calcium intake.
