Rennie Tablets

Rennie Tablets

Description:

Rennie Tablets are an over-the-counter antacid medicine formulated to provide fast and effective relief from heartburn, acid indigestion, and symptoms of hyperacidity. Each chewable tablet contains a combination of calcium carbonate and magnesium carbonate, which work together to neutralize excess stomach acid directly in the stomach, helping to relieve burning sensations in the chest and upper abdomen. Rennie is suitable for adults and adolescents above the recommended age (refer to local pack instructions) and is commonly used for occasional heartburn after meals, during stress, or in pregnancy under medical advice. The tablets are designed to be chewed, making them convenient to use anytime, anywhere without the need for water.

Indications:

• Symptomatic relief of heartburn (acid reflux) and acid indigestion.
• Relief of hyperacidity and sour stomach.
• Relief of epigastric pain and burning sensation related to excess gastric acid.
• Management of discomfort after consuming spicy, fatty, or heavy meals associated with excess stomach acid.
• May be used, under medical supervision, for relief of heartburn during pregnancy if recommended by a healthcare professional.
