Which side effect is commonly associated with magnesium-containing antacids?

• A. Constipation
• B. Diarrhea
• C. Nausea
• D. Headaches

Answer: (B)

Magnesium-containing antacids are commonly associated with diarrhea as a side effect. This occurs because magnesium has a laxative effect on the digestive system. When magnesium ions are present in the intestines, they can draw water into the bowel, which increases stool fluidity and can lead to loose stools or diarrhea. While other gastrointestinal side effects can occur with different types of antacids (for instance, aluminum-based antacids may cause constipation), magnesium specifically is known for its tendency to promote a looser stool consistency. Understanding the properties of different components in antacids helps in predicting their side effects, and this knowledge is crucial for managing patients’ digestive health effectively.
