Yes,you can take both of them. Imodium- loperamide is used to treat sudden diarrhea (including traveler s diarrhea). It works by slowing down the movement of the gut. This decreases the number of bowel movements and makes the stool less watery. It is also used to treat on-going diarrhea in people with inflammatory bowel disease. Loperamide treats only the symptoms, not the cause of the diarrhea (e.g., infection). Treatment of other symptoms and the cause of the diarrhea should be determined by your doctor. Your diarrhoea is because of disturbances gut flora as result of amoxyllin. You can also take prebiotics and probiotics (vibact) to restore normal flore and discontinue this antibiotics. You consult your physician for any change or add on treatment rather than doing self medication. Thanks.
