A larger double-blind, controlled trial showed that prednisolone significantly shortened the time to complete recovery, while valacyclovir did not affect facial recovery compared with placebo. [13] Further analysis showed that patients treated with prednisolone within 48 hours had significantly higher rates of complete recovery than did those who were not treated, whereas no significant difference in recovery rate was seen between patients treated at 49–72 hours and untreated patients.
