A woman I know was Dx'd with depression and PTSD, she was already on Lexapro 10mg from Gen Prac but it wasnt doing enough so she went to a Psychiatrist and was upped to 20mg, caused vision problems and severe headaches. Today she saw him and he Rx'd Cymbalta 30mg for a week then 60mg in conjunction to the Lexapro, has anybody heard of this? it seems like way too much Serotonin to me
