Actually, Bedford is recommending that the preservative free MTX be stored
in syringes to maximize storage life and get multiple doses from a vial.  I
take 20 mg/week; that's 0.8 cc.  So when I open a vial, I draw two full
syringes and a half a dose.  I recap one of the full syringes and the half
dose and put them in a bag, then take the other dose.  Two weeks later I
inject the half dose into a new vial, then draw three complete doses.  This
way I get 5 doses from two vials.

Again, this is per manufacturer's guidelines.

As to the preservative vs. non-preservative, I believe the story is that the
two manufacturers that were shut down by the FDA (which is what caused the
shortage) have only been certified to produce MTX with preservative.
Bedford will continue to produce the preservative-free variant, which those
of us who are sensitive to the preservative will need.

Also, Bedford announces the release of each batch in advance and pharmacies
are instructed to call and order what they need on the release day - not
before.  Following these instructions, my pharmacist has always been able to
get what she asks for.  But other pharmacists in the area, who don't follow
instructions, don't get any.

Finally, if someone is taking injectable MTX orally, they might consider
switching to the IV solution instead.  It can also be taken orally and has
not been in as short a supply.
