Loose motions. Switch to rifagut 200?

Good morning Sir/mam 1st-From last one week i am noticing that i do not pass stool completely at once. 2nd- as soon as i wake up in early morning ,immediately i feel cramps and pain at lower abdomen and within 1-2 minutes i feel uncontrollable stool.and this pain and cramps comes only at morning just after waking and then dont come for anytime of the day. Please guide me doctor why is it happening what may be the cause ,else nothing is happening,please provife some antibiotics or whatever required,i already tried ornof 2 times a day for 1 day but i didnt work now should i take it for atleast 3 4 days or my problem may be ibs with infection hence i should switch to rifagut 200? Your response will be very helpful to me as i cant take any personal or paid consultation now hence asking for medication. Thank you!
