Acidity and heartburn are commonly caused by excess stomach acid irritating the lining of the stomach and esophagus. A medication like Topcid 40 Tablet, which contains famotidine, can help reduce acid production and relieve these symptoms.

Treatment suggestions:

• Famotidine (such as Topcid 40) is often prescribed to reduce stomach acid and improve heartburn and acidity.
• Avoid spicy, oily, and heavy meals; eat smaller, frequent meals instead.
• Avoid lying down immediately after eating and reduce caffeine, alcohol, and smoking.
• Maintain a healthy weight and avoid tight clothing around the abdomen.

When to see a doctor:

• If symptoms persist despite treatment or worsen.
• If you experience difficulty swallowing, persistent vomiting, weight loss, or black stools.
