Treatment of idiopathic sensory-motor polyneuropathy depends on controlling neuropathic pain, which can be treated with anti-seizure medications, antidepressants, or analgesics including opiate drugs. In severe painful conditions, patients may be referred to the Blaustein Chronic Pain Clinic for a multidisciplinary approach to pain management. Patients with balance problems often benefit from ‘gait’ training through physical therapy. Patients who have foot drop due to weakness in their ankles may benefit from orthotics.
Prevention of Contrast-Induced Nephropathy
Neuropathic pain can be contrasted to nociceptive pain, which is the type of pain which occurs when someone experiences an acute injury, such as smashing a finger with a hammer or stubbing a toe when barefoot. This type of pain is typically short-lived and usually quite responsive to common pain medications in contrast to neuropathic pain.
Neuropathic pain, or pain caused by the injury to a nerve or nerves, is often difficult to control. Mild pain may sometimes be alleviated by over-the-counter analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs). More chronic and discomforting pain may need to be addressed through the care of a physician. Medications that are used for chronic neuropathic pain fall under several classes of drugs: antidepressants, anticonvulsant medications, antiarrythmic medications, and narcotic agents. The antidepressant and anticonvulsant medications modulate pain through their mechanism of action on the peripheral nerves, spinal cord, or brain and tend to be the most effective types of medications to control neuropathic pain. Antidepressant medications include tricyclic antidepressants such as amitriptyline or newer serotonin-norepinephrine reuptake inhibitors such as duloxetine hydrochloride or venlafaxine. Anticonvulsant medications that are frequently used include gabapentin, pregabalin, topiramate, and carbamazepine, although other medications used for treating epilepsy may also be useful. Mexiletine is an antiarrythmic medication that may be used for treatment of chronic painful neuropathies.
