Consume soft foods like rice, curd, bananas, and cooked vegetables at regular, short meals. Steer clear of late-night meals, tea and coffee, alcohol, smoking, and spicy or oily foods. Incorporate probiotics, drink enough water, and avoid lying down right away after eating.

Pantoprazole is a commonly used medicine for severe acid reflux and gastritis, and many people with long-standing reflux disease may need it for extended periods under medical supervision. Since you develop heartburn quickly after missing the medicine and also experience food reflux into the mouth, it suggests that your acid reflux is quite significant and may require proper long-term management rather than suddenly stopping the medicine. Long-term use of pantoprazole is generally considered safe for many patients when monitored properly, but using it continuously for many years may sometimes increase the risk of low vitamin B12, low magnesium, calcium deficiency, bone weakness, kidney problems, or certain infections in some individuals. This does not mean everyone will develop these problems, but regular medical follow-up is important. Because your symptoms are severe and persistent, you should consult a gastroenterologist for a detailed evaluation, and tests such as endoscopy may sometimes be needed to check for conditions like severe reflux disease, hiatal hernia, or damage to the food pipe. Lifestyle changes are also very important and may reduce symptoms significantly, including avoiding spicy and oily foods, tea, coffee, alcohol, smoking, overeating, and late-night meals, maintaining a healthy weight, eating smaller meals, and keeping the head slightly elevated while sleeping. Do not stop pantoprazole suddenly on your own because acid rebound can worsen symptoms. Your doctor may decide whether to continue the medicine, reduce the dose gradually, switch treatment, or evaluate other options depending on your condition. With proper medical supervision and lifestyle management, long-term reflux can usually be controlled safely and effectively.
