I tried prozac - didnt work at all even on higher dosage. will this mean other ssris wont work for me? also do all antidepressants have an impact on libido? is this permanent whilst taking or just for 1st 2 weeks?fastest acting ssri for anxiety?

Prosac is an archaic remedy, with not only libido side effects, but also risk of suicide. Many other SSRI's and SSNRI's are available and add-on of Deplin is often successful. See your psychiatrist and get medications adjusted or switched, but be aware, you will likely encounter a variety of adverse effects as you search for your most impactful drug. May take several weeks.
