Can rennies be harmful

Rennies, which contain antacids like calcium carbonate, are generally safe for occasional use to relieve heartburn and indigestion. However, overuse can lead to side effects such as constipation, diarrhea, or imbalances in electrolytes. Individuals with certain medical conditions, like kidney disease, should use caution and consult a healthcare professional before using them. Always follow the recommended dosage to minimize potential harm.
