Hundreds of drugs are in short supply around the U.S., pharmacists warn

A growing number of drugs are in short supply around the U.S., according to pharmacists. 

In the first three months of the year, there were 323 active medication shortages, surpassing the previous high of 320 shortages in 2014, according to a survey by the American Society of Health-System Pharmacists (ASHP) and Utah Drug Information Service. It also amounts to the most shortages since the trade group started keeping track in 2001.

"All drug classes are vulnerable to shortages. Some of the most worrying shortages involve generic sterile injectable medications, including cancer chemotherapy drugs and emergency medications stored in hospital crash carts and procedural areas," ASHP said in a statement.
