"It was good overall with all the gold medals but I was hoping for some faster times," the 24-year-old world record holder said.
"I wanted to be a little bit faster, but hopefully I'll come back to the same level I did at the 2017 World Championships."
Sarah Sjöström had been worried she had broken her thumb at the finish of Wednesday's 100m freestyle, in which she took gold. However, an X-ray revealed there was no break and she was clear to race on the final day of swimming action in Glasgow.
Sweden's Olympic champion raced to victory in 25.16 seconds to take the 14th European gold of her successful career.
Sjöström also won gold this week in both the 50 and 100 free and in the 100 butterfly. Sweden's other swimmers in the team failed to win a medal.
