Seven trials were included. The diagnosis, steroid regime, outcomes and methodological quality varied between trials. The sample size ranged from 24 to 94. For sore throat the results of two studies suggest a benefit at 12 hours of steroid therapy over placebo; however this benefit was not maintained. The evidence from one trial suggests a longer benefit when the steroid is combined with an antiviral drug. There was evidence from one trial that steroids may improve resolution of fatigue around four weeks; however it is unclear if this is only in combination with an antiviral. Two trials reported severe complications in participants in the steroid group.
