How long for Prozac to start working? Went from 20 to 60?? It's been 4weeks?

I dont know. Sounds like the prozac has been in your system already only at a lower dose. Therefore it shouldnt take as long as it would take for someone just starting it for the 1st time. I'd say as is it shouldnt take any longer than a month to notice a difference if your going to. Now someone starting it for the 1st time can expect it to potentially take excess of a month to start noticing a difference. If your not noticing any help at all I would call your drs office and ask them about it. Sometimes you can take a medication at one point and get tremendous relief. Where as when its taken again down the road it dont work as well and you have to try something else. Your dr will have an idea if this is the case for you or not. I'll keep you in my prayers. Hope you get back to feeling yourself soon. Hang in there and keep trying dont give up. Sometimes it takes awhile to get the right med and dosage to help you.

4-6wk usually

I was on Prozac for three years. I thought it would NEVER work! It took 5 weeks to the day! I woke up that morning and as soon as I opened my eyes, I knew! I didn't have that kicked-in-the-gut feeling. It was like a cloud had lifted. Good luck! I hope this helped.

I have never been on Prozac. I know that most of the antidepressants usually take up to a complete month to feel the effect. it all depends on how your system adjusts to the medication. I hope someone that has been on the medication can give you a more accurate answer. Please do not hesitate to call your doctor though. I have been on the line with mine every day since last Friday and finally spoke to her today after 6 days of the runaround. Don't give up and know that we as a community of people dealing with the same situations will keep you in prayer. God bless you and I hope you get to feeling better. It will get better in the long run. Smile for me.
