I have taken Prozac for a year at 10 mg. I started taking 10 mg the first month and then increase it to 15 mg and took it for a few months and then just took 10 mg. I went to my doctor on November, and he wanted me to still take Prozac at 10 mg and I also take Klonopin when need it. This past week, I have been having more anxiety, and i think i Should increase the Prozac dosage to 15 mg or wait for a bit until I call my doctor.
