Thanks for writing your query.
After readingyour post, it seems that you are having antibiotic induced diarrhoea
Antibiotics usually destroy the normal bacterial flora present in the intestine.
These bacteria are useful bacteria which help in the process of digestion and absorption of food.
Destruction of these bacterial flora result in loose soft and frequent stools.
You should take Lactobacillus
preparation to regain this lost useful bacterial flora. Once the flora is regained, you will feel relief from your symptoms.
Eating yoghurt will also be beneficial.
I hope this is helpful to you.
