Yea this is new with this drug. They are also covering it weird. My GI writes the script for 30 days treatment and double the strength. I use it for 2 weeks then save the rest for 2 weeks the following month then repeat. I was able to get it on a 2 refill max now I have to call in for the refill. Mine is still covered though with no copay just different rules. This drug is the least effective though for me. I have to combine it with other antibiotics.
