I have noticed swollen lymph nodes in my armpits and groin since starting Copaxone almost 3 months ago. Can Copaxone cause swollen lymph nodes? Is this a common side effect? If so, anything that can or should be done to help?
Copaxone sometimes causes swelling of draining lymph nodes. THis is rarely a problem unless painful. There have been some case reports of cancerous swelling of lymph nodes in people on Copaxone but it is not at all clear that there is a causal relationship. There is nothing to do about the swollen lymph nodes except stopping the Copaxone.
