These are nerves that are not in the brain or spinal cord. Neuropathy secondary to drugs causes a loss of sensation or movement in a part of the body due to nerve damage from taking a certain medicine, combination of medicines, or illicit (street) drugs.Loss of sensationNumbness and tingling are abnormal sensations that can occur anywhere in your body, but they are often felt in your fingers, hands, feet, arms, or le...ImageRead Article Now Book Mark Article Causes The damage is caused by the toxic effect of certain medicines or illicit (street) drugs on the peripheral nerves. There may be damage to the axon part of the nerve cell, which interferes with nerve signals. Or, the damage may involve the myelin sheath, which insulates the axons and increases the speed of transmission of signals through the axon.Most commonly, many nerves are involved (polyneuropathy). This usually causes sensation changes that begin in the outside parts of the body (distal) and move toward the center of the body (proximal). There may also be changes in movement, such as weakness. There may also be burning pain.DistalDistal refers to sites located away from a specific area, most often the center of the body.

The drug causing the neuropathy may be stopped, reduced in dose, or changed to another drug. (Never change or discontinue any drug without first talking to your health care provider.)Your provider may suggest the following drugs to help control pain:Over-the-counter pain medicines may be helpful for mild pain (neuralgia). Phenytoin, carbamazepine, gabapentin, pregabalin, duloxetine, or tricyclic antidepressants such as nortriptyline may reduce the stabbing pains some people experience. Opioid pain medicines such as morphine or fentanyl, may be needed to control severe pain.There are currently no medicines that can reverse the loss of sensation. If you have lost sensation, you may need to take safety measures to avoid injury.Ask your provider if there are exercises that can help relieve your symptoms. Outlook (Prognosis) Many people can partially or fully return to their normal function. The disorder does not usually cause life-threatening complications, but it can be uncomfortable or disabling. Possible Complications Complications may include:Inability to function at work or home because of permanent loss of sensation Pain with tingling in the area of the nerve injury Permanent loss of sensation (or rarely, movement) in an area of the body When to Contact a Medical Professional Contact your provider if you have a loss of sensation or movement of any area of the body while taking any medicine. Prevention Your provider will closely monitor your treatment with any drug that may cause neuropathy. The goal is to keep the proper blood level of the drug needed to control the disease and its symptoms while preventing the drug from reaching toxic levels.Open ReferencesReferencesJones MR, Urits I, Wolf J, et al.
