I took a script to my pharmacy & my insurance probably won't cover it (I was told maybe by the pharmacy, but then no by the doctors office, his nurse had seen this before). In the meantime, it can take up to 20 days before the answer comes back as a no. This is 20 days without it. Can I get the script back from the pharmacy & take it somewhere else & just pay cash? I'm due & the script is for phentermine. I am overweight & it works well.
