(Reuters) - Pharmacy chain Walgreen Co suffered a system outage for several hours on Friday, taking all of its 8,200 pharmacy outlets offline and delaying prescription orders.
The company faced a "technical issue" during a system update and had to bring the entire system offline to resolve it, spokesman Michael Polzin said.
Some prescription orders may have been lost as a result of the outage, Polzin said, but most were queued and processed when the system was restored.
The pharmacy system was back online by 02:00 p.m. ET.
Shares of Walgreen closed at $61.05 on Friday on the New York Stock Exchange.
(This version of the story was corrected to say "orders may have been lost" from "orders were lost" in paragraph three.)
