Rennie Dosage Guidelines Rennie antacid tablets, used for heartburn and indigestion relief, have clear daily limits based on product instructions. The standard maximum is 10 tablets per day for most variants like Spearmint or Peppermint, taken as 2 tablets chewed or sucked 1 hour after meals and at bedtime, with extras for heartburn as needed.

Recommended Usage

  • Adults and children over 12 : Start with 2 tablets after meals or before bed. Add 2 more between doses if heartburn persists.
  • Daily cap : Never exceed 10 tablets in 24 hours. Some variants allow up to 11 or 16, but stick to the pack's leaflet.
  • Under 12 years : Not recommended without doctor advice.

Key Safety Warnings

  • Duration : Limit to 14 days max. Persistent symptoms? See a doctor—could signal underlying issues.
  • Special cases :
    • Kidney problems: Consult a doctor first, as magnesium buildup risks low blood pressure or nausea.
* Pregnancy/breastfeeding: Generally safe short-term, but check with a pharmacist.

* Avoid with: Large milk amounts, certain meds (e.g., eltrombopag—space by 1-4 hours).
  • Overdose signs : Nausea, vomiting, constipation, thirst. Drink water and seek medical help.

Why Limits Matter

Exceeding doses risks hypercalcemia (high calcium) or hypermagnesemia (high magnesium), especially long-term, leading to serious effects like fatigue or irregular heartbeat. Always chew thoroughly for fast action—works in minutes by neutralizing stomach acid.

TL;DR Bottom : Max 10 Rennies/day for adults; chew 2 as needed after meals. Don't exceed 14 days—consult a pro for ongoing issues.
