Adler was going to be the first choice at the 2010 World Cup in South Africa before a rib injury ruled him out of the tournament and installed Bayern Munich's Manuel Neuer as the first pick, a position he has held ever since.
Adler's last international appearance was on Nov. 17, 2010, in a friendly against Sweden.
"I am delighted that Rene has found his old form after his long injury," said Loew. "He should now also get a chance to present himself on an international level."
A string of injuries led to the former Bayer Leverkusen keeper missing much of last season before a transfer to the northern club and a return to fitness allowed him to enjoy a superb start to the current campaign.
Loew nominated 22 players for the side's last international match of the year in Amsterdam on Wednesday, including Roman Neustaedter of Schalke 04.
