Why aren all drugs in short supply listed on the Drug Shortage web page?
The CDER Drug Shortage Program focuses on shortages of medically necessary products since these shortages have the greatest impact on public health. The Drug Shortage page on the FDA website lists shortages of medically necessary products. Shortages that are expected to be resolved quickly or which involve only a particular strength or package size, which has a substitute strength(s) and package size(s), are not usually the focuses of the DSP.
