Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from antibiotic induced diarrhea as Clindamycin is an antibiotic and at times intake of antibiotics can cause severe diarrhoea 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 diarrhoea.. 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.. Drink plenty of oral rehydration solution.. Take more of yoghurt, rice, banana and cereals in diet.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
