Abstract

EVIDENCE-BASED ANSWER

Antivirals alone are no better than placebo for the treatment of Bell's palsy. Antivirals in addition to corticosteroids result in a modest improvement in full recovery rates compared with corticosteroids alone (SOR: B, meta-analysis of lower quality RCTs). Clinical practice guidelines recommend offering antivirals only in conjunction with oral steroids to appropriate patients with Bell's palsy (SOR: C, clinical guidelines).
