Gosh. You’re just noticing this now? Drug shortages have exploded over the last few years, with cancer drugs and critical care drugs hit particularly hard.
There are a number of causes, from the FDA closing one plant and the remaining plants being unable to keep up with demand, to raw material issues, to a company simply no longer manufacturing a medication because fixed reimbursements make it impossible to manufacture and sell without taking a loss. Most of the shortages are for drugs that are not expensive and have been around forever. Methotrexate has been around since about 1950.
In the hospital pharmacy where I work, we have, I don’t know, a hundred backorders in? And it’s all for inexpensive, older drugs that are on national shortage. We are substituting as best we can, but supply of the most common substitutes dry up eventually, because everyone is using them.
Methotrexate is certainly thin on the ground right now, but at least I got in some Taxol (commonly used for breast cancer, and we nearly ran out a few months ago). Within the last year and a half or so, we ran out or nearly ran out of Carboplatin (lung cancer and many others- I was down to my last vial), Cisplatin for og’s sake (used for nearly everything), Leucovorin, Mesna, Bleomycin (we had to do without for months), Adriamycin (breast cancer, leukemia, and Hodgkins’- down to 2 vials before the shortage resolved somewhat and we could buy some), Fluorouracil (colorectal, head & neck), Cytarabine (leukemia), Doxil (Kaposi’s sarcoma/ovarian, all stock long gone) and on and on and on. I hope we can get some vinblastine in before I use up my last three vials. I have several patients who need it.
I can’t begin to tell you how frustrating it is. Sometimes one purchasing group will get backorders partially filled and another won’t. At least I’m not the one who has to try to explain this to the patients. I keep the oncologists posted as much as I can. We’re always trying to set up backorders and call and beg for a few vials if there are any on allocation. We barely keep up. Our buyer is awesome, but she’s pulling her hair out.
If you’re interested, here’s a link from the FDA about the drug shortages. There’s a link on the page with a list of the drugs currently on shortage. Sometimes the release dates are a little, um, optimistic. Sometimes we get lucky.

I repeat: virtually NONE of these are expensive drugs. My understanding (which may be incorrect) is that the drug companies couldn’t jack up the price if they wanted to because Medicare has fixed the reimbursements in an effort to contain drug costs. That’s why the drugs on shortage are seldom the expensive moneymakers like Avastin, Herceptin, etc. It’s all those old generic things I mentioned. And starting up a new factory line to make medications to FDA specs, which are incredibly strict, can take many months.
What can be done? I don’t know…they’re talking about a law that would require manufacturers to notify the FDA when they’re planning to take down a product line, which would help a little bit down the line, maybe. The FDA might be able to clear some more foreign factories for importation, as they did with leucovorin, available from England for a while.
It’s all very frustrating and there are no easy answers. Certainly the FDA can’t order manufacturers to manufacture certain things. I wish I knew the solution.
