Early use of corticosteroid therapy results in less autonomic synkinesis and possibly improved rates of recovery in adults (strength of recommendation: C); there is no proven benefit in children (SOR: B). Adding acyclovir (Zovirax) to prednisone therapy may improve recovery rates compared with prednisone alone (SOR: C). The results of 1 nonblinded study indicate that intramuscular methylcobalamin (vitamin B12) used alone or in combination with prednisone may shorten time to recovery (SOR: C).
