I only take Librax when needed...may be 2 a day, may not be any for a week. The dr. tried having me take it every day, but that didn't help the stomach spasms...it only works for me if I take when I feel the stomach spasms starting. 90% of the time, it stops them immediately. So, you can try just taking it when needed, if the dr. approves that, and then you can worry less about
any side effects.
