Hello Dear. For gastritis more than any medicines you should follow some lifestyle tips. I will suggest you few 1. Do not eat spicy food 2. Take medications without fail as prescribed by your doctor 3. Take little food at frequent intervals. Breakfast around 8am, small snack at 11am, lunch at 1pm, small snack at 4pm and dinner at 8pm 4. Drink plenty of water 5. Do not smoke, take alcohol or tobacco and even excess of coffee and tea 6. Do not take much of stress. Stress aggravates gastritis 7. Do regular exercise. Atleast half an hour per day 8. Learn meditation techniques 9. Follow this regularly for 21 days. It is said that anything you practice regularly for 21 days becomes a habit There is no medicines without any side effects. But side effects will appear only on long term usage. No harm in taking for short duration upto a month or two. You can take tablet pantop or tab omez along with mucaine gel. Hope i have answered your question. Feel free to contact me if you have any more questions. I ll be glad to help you. All the best With warm regards Dr Sanjay Kini
