A drug used to treat children with leukemia is in short supply, so short that some hospitals fear they may run out of it.
The critical shortage of the drug methotrexate means that chemotherapy sessions for some children with leukemia at local hospitals have been changed or cut back.
The nationwide shortage is because a factory in Ohio making the drug has been shut down because of quality control concerns.
It's also because methotrexate doesn't produce a big profit margin for drug companies, so other companies have simply stopped making it.
Right now children who need the drug are being scheduled for treatment on the same day. Others are not given the full doses they used to get. And nationwide supplies might start running out in some places within days.
