Bell’s palsy is treated symptomatically (i.e. the symptoms are treated rather than the disease itself) because mostly it recovers on its own.
One important symptomatic management is the management of dry eyes. Since the sufferer’s of Bell’s palsy can’t close their eyelids due to weakness of eyelid muscles (which are supplied by facial nerve) cornea can become dry due to continuous exposure to the environment. To deal with this problem affected eyelid can be closed with a piece of paper tape to avoid drying of cornea.
Eye muscle massage also can be done for the weak eye muscles.
Corticosteroids are often used as short course to hasten recovery. Prednisone can be a good choice. For 5 days 40-60 mg prednisone can be given followed by a gradual tapering over the next 5 days.
Usefulness of anti-viral medications like acyclovir are doubtful.
