I ve been taking brand name Zoloft 50 mg for about 13 years.... It doesn t feel white as effective as it once did...?
You can become resistant. Increasing the dosage will not help. Maybe your psychiatrist will switch you to Prozac. There are near medications out there that may be more effective for you. I have not experienced this myself, but my father did the last years of his life. Neither Zoloft or Prozac worked for him according to him.
You are probably having what is known as SSRI Poop Out, which is that your med not longer is working for you. I would try a higher dose. This happened to me with Celexa. I switched to generic Welbutrin and things got better.
