Has anyone taken the drug Remeron? The generic form is Mirtazapine. My doctor prescribed 15 MG to be taken at bedtime. I am currently taking Effexor and Ativan. I take the Effexor in the morning and the Ativan at night. I have had no problems with this combination but have been a little more depressed lately. I just started taking the Remeron and I feel awful. I can hardly wake up and feel extremely dehydrated. I am going to tell my doctor I can't handle this medication. Just wanted to see what the outcome has been for others on this drug... Thanks!
