Walgreens customers across the U.S. may find it difficult to get prescriptions in the company’s stores this week.
The company’s pharmacists have been filling each prescription manually since their system crashed Tuesday morning, affecting all 8,200 drugstores in America, The Chicago Tribune reported.
A Walgreens spokesman told NBC Chicago they have experienced "technical issues" following a “recent maintenance procedure.”
“Our pharmacies are still able to fill prescriptions and process most insurance claims, however some patients may experience longer wait times until certain functionalities are fully restored,” company spokesman James W. Graham said in an email.
“We apologize for any inconvenience this may have caused, and our IT and pharmacy operations teams are working diligently to correct the issue,” Graham said.
The company is based in Deerfield, Illinois.
