In April, 2013 I had a gallstones attack (my 2nd attack in maybe 5-7 years) and an emergency room dr prescribed me Glycopyrrolate 1 mg tab, qty 12 tabs. Since 4/13 I took 1 when I felt allot of discomfort and I thought I was about ready to have a gallbladder attack. After I took 1 my relief was just about immediate and the discomfort gone. The past few or so days I been having the same discomfort; I feel an attack might come on do you think I could take 1 tab? I m also taking generic bactrim ds tab for a bladder infection plus earlier I had to take a tension headache tab (generic imitrex). Please help. Thank you.
