There are no medications specifically approved to treat Bell's palsy. Underlying medical conditions that lead to facial nerve disorder are treated specifically according to the specific condition that is responsible for the damage to the nerve. Steroid medications ( corticosteroids ) are the best treatment for Bell's palsy, and it is recommended that all patients be treated. The usual amount is one milligram per kilogram body weight of prednisone (or steroid alternative) per day for 7 to 14 days. Recently, antiviral medications like acyclovir ( Zovirax ) given in conjunction with steroids have been demonstrated to increase recovery. Doses of the antiviral agent will vary with the drug chosen.
Regardless of the trigger, Bell’s palsy is best described as an event – trauma to the nerve. As with any other injury, healing follows. The quality and duration of recovery is dependent on the severity of the initial injury. If the nerve has suffered nothing more than a mild trauma, recovery can be very fast, taking several days to several weeks. An “average” recovery is likely to take between a few weeks and a few months. The nerve regenerates at a rate of approximately 1-2 millimeters per day, and can continue to regenerate for 18 months, probably even longer. Improvement of appearance can continue beyond that time frame.
Bell's Palsy is a facial nerve disorder in which the nerve that controls muscles on one side of the face damaged, resulting in weakness or paralysis that can cause the affected side of your face to droop. The exact cause of Bell's Palsy is unclear (it may be caused by a virus), so there is no known way to prevent or cure it. Luckily, Bell's Palsy usually clears up within a few weeks or months, and there are some things you can do to aid in the recovery process.   Your doctor can prescribe medications and you should also follow at-home care methods to speed recovery time. There are also alternative methods that are not proven to cure Bell's Palsy, but which may ease symptoms caused by it.
