i've called at least 10 compounding pharmacy trying to fill a high concentration ( 10,000 µg/ml) injectable methylcobalamin script. No luck, outside of a quote or $175 plus overnight refrigerated shipping costs. i'd love some suggestions for compounding pharmacies to try. I tried skips and McGuffs. the concentration is the issue. my second question is if I can get my doctor to lower the concentration level of the methylcobalamin, I think I can fill the script easier ( this stems from discussions with the pharmacists I have talked to)... does anyone have recommended compounding pharmacies to try? price and Customer service matterrto me.. thanks in advance.
