My serum ige levels were high (887). So my doctor wrote me prescription for allegra-m (1/day), rantac 150 mg (2/day) and banocide 100 mg (3/day) tabs for a course of 21 days. The issue is ever since I've started this course, usually after dinner i'm suffering from heavy bloating and sometimes breathlessness. So two questions:- (1) is there any way to prevent this from happening? And (2) can I stop taking these medications mid-course? Will there be an issue? Thanks in advance.
