To relieve your symptoms, you can try over-the-counter generic medications. For the acidity and stomach irritation, an acid-reducer like omeprazole (20mg once daily before breakfast) can help. For the constipation, a gentle osmotic laxative like polyethylene glycol is effective and safe. Please avoid calcium or aluminum-based antacids, as they can worsen constipation. Remember to drink plenty of water and increase your dietary fiber intake. Since these symptoms have lasted for seven days, please consult a healthcare professional for a proper evaluation if there is no improvement within a couple of days.
