I was suffering from indigestion, gastric problems, nausea. Then I consulted with physician he told me that there could b possibly irritable bowel syndrome and prescribed me probiotic (Preopro HS) and antacid. Now, I am feeling completely Ok. But, I am worried that if the problem recurs later as medicines are getting over, Doc. Told me to take medicine only for 10 days. As earlier also I had same problem, I am suffering from stomach problems from last 2-3 months and every time Doctor is giving me same medicine as mentioned above but every time when medicine gets over then again problem starts. So, can any one suggest me that can I take pro biotic for longer period of time like around 2-3 months.
