As of 2015, studies indicate that steroids effectively treat Bell's palsy, states the National Institute of Neurological Disorders and Stroke. Acyclovir, a drug that combats viral herpes infections, appears to shorten the duration of Bell's palsy. For pain relief, analgesics, such as ibuprofen and acetaminophen, are effective.
If Bell's palsy prevents the patient from blinking or closing the eye, lubricating eye drops and eye patches protect the eye and keep it moist, advises the National Institute of Neurological Disorders and Stroke. Physical therapy, facial massage and acupuncture may provide minor improvement in pain and facial nerve function. Special exercises and massage of the facial muscles can prevent shrinking and shortening of the affected muscles, explains Mayo Clinic.
