Patients can consider increasing their intake of foods containing probiotics and prebiotics, such as yogurt, yogurt drinks, dried yogurt, fermented vegetables, etc., or using probiotic supplements.

6.Communicate with your doctor promptly: If diarrhea symptoms persist or worsen, patients should contact their doctor promptly. Your doctor can assess the severity of your symptoms and adjust treatment based on the circumstances, which may include adjusting the dosage of the medication, suspending the medication, or trying other treatments.
