i am trying to find the daily fda approved amount of neurontin....the insurance has suddenly decided to quit paying for neurontin, even in its generic form, stating the dr. is prescribing more than the daily fda approved allowance of 100 mg. per day....so far, i cannot find any info to confirm this statement...everything i find says up to 4,000+ is okay and my daughter takes 3000 mg daily...we cannot afford to pay $300+ per month for this [prescription....both my daughter's shrink and the insurance co. drs have huge egos which are getting in the way of solving this problem...sigh....if anyone can help me determine (a) is there is a daily fda approved amount and (2) what that amount is, and 93) where i can find this info i would be appreciative....
