I don't recommend antidepressants for concussions or PCS. The withdrawal effects can be bad, so you may have to taper the dose down.

If you look at the most severe PCS cases, Antidepressants are usually involved, so it's questionable whether there is a benefit, or if they screw you up. And some of the people taking them have been struggling for over a decade. They may provide temporary relief, but they're not good for long term recovery.

I'd recommend other depression treatments, like a healthy diet and exercise routine. Depression is also linked to imbalances in the gut microbiome, so incorporate Gut Health into your treatment plan.
