NINDS Bell's Palsy Information Page

Recent studies have shown that steroids such as prednisone -- used to reduce inflammation and swelling -- are an effective treatment for Bell's palsy.  Other drugs such as acyclovir -- used to fight viral herpes infections -- may also have some benefit in shortening the course of the disease.  Analgesics such as aspirin, acetaminophen, or ibuprofen may relieve pain.  Because of possible drug interactions, individuals should always talk to their doctors before taking any over-the-counter medicines.   Keeping the eye moist and protecting it from debris and injury, especially at night, is important.  Physical therapy to stimulate the facial nerve and help maintain muscle tone may benefit some individuals.

The prognosis for individuals with Bell's palsy is generally very good. The extent of nerve damage determines the extent of recovery.  With or without treatment, most individuals begin to get better within 2 weeks after the initial onset of symptoms and recover completely within 3 to 6 months.

The National Institute of Neurological Disorders and Stroke (NINDS) conducts and supports an extensive research program of basic science to increase understanding of how the nervous system works and what causes the system to sometimes go awry, leading to dysfunction. Part of this research program focuses on learning more about the circumstances that lead to nerve damage and the conditions that cause injuries and damage to nerves. Knowledge gained from this research may help scientists find the definitive cause of Bell's palsy, leading to the discovery of new effective treatments for the disorder. Other NINDS-supported research is aimed at developing methods to repair damaged nerves and restore full use and strength to injured areas, and finding ways to prevent nerve damage and injuries from occurring.
