There is no medical treatment for nerve damage that works for everyone undergoing chemotherapy. Many treatments are still in the experimental stage. The most effective treatment largely depends on the type of chemotherapy drug being used. This is because different drugs "damage" the nerves differently.
Drugs Researchers are testing drugs against the nerve damage that causes CIPN. Early research shows that certain drugs may help, depending on which chemotherapy drugs a person takes. However, a 2014 review from the journal Cancer Management and Research says current information on the effectiveness of these drugs is controversial and requires more research.
