The Red Devils remain in second-place on the table after going down 2-1 at Old Trafford.
They are one point behind Manchester City - who have got a game in hand - but Solskjaer insists it isn't time for panic stations.
"There will be no big inquest," he said. "There have been so many odd results this season but with the world as it is we have been the most consistent team, it hit us today."
Solskjaer added that United did not have their usual spark against the Blades.
"We had all the possession but when you concede two bad goals it's always going to be difficult. We didn't create big enough chances to score enough goals.
"That magic was missing, that little bit extra. They defended well, fair play to them but we didn't have the right ideas or solutions. The first goal is a foul, Billy Sharp runs into David de Gea. At the other end, no foul for the disallowed goal for us but it's that kind of season. Two mistakes by the referee.
"It wasn't to be, the second goal we conceded is so poor, so sloppy. Easy. We stopped getting out to the ball, three or four bad decisions which is out of character."
