Cymbalta for concussion?

My 15 year old daughter suffered two concussions playing soccer. Three weeks after the initial concussion, she got another one. This second concussion has been tough for her. It has been over 4 months and while she is improving, she is still symptomatic. Her doctor prescribed Amantadine, which she has been taking and we think it helps. The doc says she has now been on it for three months and wants her to switch to Cymbalta. My husband took her to the appointment and is unable to share "why" the doctor wants her to take this. She is not depressed, anxious or anymore emotional than any other teenage girl. Looking this drug up, there is no evidence based practice for prescribing this medication. Reading about others struggles with it, it's side effects, difficulty discontinuing it, etc it seems like a big risk to take this medication. Does anyone here know WHY an antidepressant is prescribed for a concussion?

Hi!
If your daughter has symptoms such as tension headaches and maybe some degree of depression and post traumatic stress then antidepressants will really help her. However, since it is difficult to assess her situation on net, you need to discuss this with hr doctor. Since your daughter has been on Amantadine for three months, maybe her doctor feels that there hasn’t been significant improvement in symptoms from this drug and hence has switched to a different group of drugs. Please discuss with her doctor or your family doctor if he is aware of your daughter’s case. Take care!
