I took the drug when I was going through cancer treatment. The entire event is a blur to me now, but at the time, with the doses I was taking, I was not feeling so hot. I suspect the dose you are being asked to take is much less. I do not have any long term side effects from the treatment, that I know of. It has been well over 20 years - so the drug has not been taken off the market yet.... seems tried and true.

I know they use Methotrexate for lots of things today.
