Hi.. It seems that you are suffering from antibiotic induced diarrhea and other side effects of antibiotics and at times intake of antibiotics can cause severe diarrhea as well as digestive disturbances.. This happens because the antibiotics disrupts the good bacteria present in intestines along with harmful bacteria and it leads to disturbances in the complex functioning of intestines like Digestion and Absorption and it leads to diarrhea.. It is however temporary and resolves as the antibiotic intake is stopped.. You can consult your treating physician if the symptoms are severe.. As of now, till you are on medication you should take empty stomach Pantoprazole or Omeprazole.. Take Loperamide to control loose motions and Ondensarton to reduce vomiting.. Drink plenty of oral rehydration solution.. Take more of yoghurt, rice, banana and cereals in diet.. Hope I have answered your query. Let me know if I can assist you further.
