Keep in mind that all medicines have LOTS of possible side effects. It is the manufacturers responsibility to list every single case of illness that study participants suffered while they were on the medication/s.
Doctors will do regular tests if there is a reasonable possibility that these side effects may pop up during treatment. Blood tests every few months will pick up possible side effects, usually before it's too late to suffer any permanent damage.
You may want to post this Q about your newly prescribed med in the medications forum, in hopes of getting more responses. Best wishes to you ~ and
