(Reuters) - Pharmacy chain Walgreens 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 2:00 p.m. ET.

Shares of Walgreen closed at $61.05 on Friday on the New York Stock Exchange.
