It is not uncommon to have children complain of frequent stomachaches, especially if they eat out often. Parents may consider over-the-counter medications, such as Pepto-Bismol for kids, in such cases. Pepto-Bismol (Bismuth Subsalicylate) is considered a safe and effective medication for gastrointestinal troubles such as acid reflux, diarrhea, and indigestion. But what should be the dosage of Pepto-Bismol for children? Read on to find out the mechanism of action, the recommended dosage, safety, side effects, and alternatives for Pepto-Bismol in children.
At What Age Can A Child Take Pepto-Bismol?
Pepto-Bismol is used to treat several digestive problems such as diarrhea, indigestion, nausea, gas, burping, heartburn, and the feeling of fullness. However, only children aged 12 years and above can take Pepto-Bismol. Do not administer it to younger children without a doctor’s consultation (1).

Hence, for children aged between 2–11 years, an alternative medication called Pepto Kids can be given instead (2). It is a formulation made specifically for younger children.
