Hi 'all! Myself and another member here have just started taking Prozac and we're feeling quite 'strung out'... nervous, heightened anxiety. Could anyone whose had experience with Prozac comment re: whether or not the anxiety levels out after awhile; how long that took to happen; if the heightened anxiety from it did in fact go away or was a side effect that was intolerable and prompted a switch in meds... etc etc. Any and all input is greatly appreciated! Thanks so much, hope you're all as well as can be, A.B.H.

After 14 weeks, it never leveled out for me! My best to you! Don't suffer too long!
I am also done with this... How are you now?
Sorry to report that I stayed on Prozac 40 mg for 12 weeks and the anxiety NEVER got better, just worse.
Would wake up, after very little sleep, with chest pounding, hot and sweaty, and overall misery in my body!
Please know your own body. If after 6 or 8 weeks, with whatever results, make your decision what YOU should do!
I am now on a low dose amitriptyline 10mg. It works for my anxiety. Have never had depression.
My best hope for success for you! God loves you!
I saw my GP and my pharmacist yesterday and they told me to give myself and Prozac a chance ! My GP gave me another 10mg so now i'm gonna be at 30mg. I do have depression and anxiety but never this bad, i'm off work until April so I want to settle this before anything else. My body and my mind feel like ''crap'' I want to feel happy again. Thank you ! :O)
It sucks because its so common with prozac since its a stimulant type of anti depressant. When it does work it really works for the panic. It took me a while to get over the hurdles of prozac.
Took me 5 months but I'm fine now. Just keep w it n it will even out
Thank you it sure helps to know others opinion. I see some people it starts to work at different times but the GP and pharmacist told me at least 6 weeks. They added another 10mg to mine two days ago, now i'm on 30mg. Hope it works out. Bless you :o)
I have been on prozac for about 5 weeks and i've been strung out ! big time with Anxiety, nervousness and it's making me think i'm crazy. My heart is racing , I have palpitations I don't know if it's related to Prozac or it's a side effect that is going to go away after awhile, I just know that it's been too long for me I am fed up of feeling this way. I had anxiety before BUT NEVER like this ! Hope this helps people.
Hi. I have been on 10mg of Prozac for about 6 weeks. I too, noticed the increased anxiety at the beginning but decided to hang in there. I did notice an improvement after about 4 weeks. By 6 weeks I was feeling pretty good (better than without the medicine). After two months of usage my doctor suggested I go to 20mg. I haven't been able to sleep for about 4 days now, and have so much anxiety. I called my doctor and asked him to change it back to 10mg. It amazes me how quickly my body responded (negatively) to an additional 10mg. Im so hoping that things level out soon now that I am back on the 10mg dosage.
Last year, a doctor put me on Prozac because my anxiety was off the chain!!! After 14 weeks, my heart raced, my face stayed flushed, heart raced especially in the mornings after taking the Prozac 20 MG, could not sleep at all! Since my age is in my 70's, this was really a bad situation. This particular doctor said, "Keep taking it; it will eventually work!" It did not! This doctor thought I was mentally unstable! Found another doctor who agreed with my research, showing that I had a treatable medical condition which caused my intense pain and anxiety!
Anxiety is not completely gone, especially here with all the holiday adventures; but, much more tolerable than the state of health caused by Prozac! Everything does not work for everyone. Try it for a number of weeks and if not working by 7 or 8 weeks, try something else because it is easier to get off Prozac if not taking for long periods of time. Do your research!
After a month on a medicine for the medical condition, and also starting water aerobics, the anxiety all but went away. Take care of yourself and try your best to enjoy the holidays! Merry Christmas!
I started Prozac 6 days ago and was feeling great until last night I had the worst panic attack I’ve ever had. I had 6 in the er. Is this due to Prozac?
Yes probably. Its a tough med to start. I had these experiences with alot of the SSRI meds though. It takes you to get worse before you get better. Hang in there.
Hi, L! It's most likely because your Prozac isn't fully effective yet ~ antidepressants/anxiolytics don't work like many other medications. It can take 4-6 weeks to feel the full benefits and 6-8 weeks to reach therapeutic levels in your bloodstream. At first, you may even feel an increase in your anxiety levels but this side effect should subside within a week or two.
If you continue feeling panicky in the next few weeks you might ask your doctor about another ultra short-term medication that works immediately... but won't prevent future attacks like your Prozac will soon.
I'm in week 6 on 40MG Prozac and am having increased anxiety, jitteryness, enlarged pupils, almost feeling manic. It lasts all day and generally subsides by evening. At night i take Mirtazapene (spelling?) which makes me very drowsy and calm. From reading these posts, especially the 2017 comments... it appears I'm not alone in having terrible side effects.
For the first few weeks I was given Klonopin to help with the side effects, but doc doesn't want me on that all the time. 6 Weeks seems like I should feel better but I feel worse, too sick to work even.
I recently tried Prozac to help treat anxiety and within 3 days of taking 20mg (just 3 pills) I began to have severe constant anxiety and panic attacks. I’ve been weening off cymbalta for many many months after a decade of use, I also used to take clonazapam but haven’t for about 10 months (that was a nightmare!)
I can’t help but feel that it was
The Prozac that upset the Applecart for me. Of course I quit taking any, and of course everyone is different but I doubt I’ll ever try that med again. I’m only now starting to feel better and it’s been 5 days since my last dose.
it took me 3 weeks. but w the help of klonopin i made it through. unfortunately Prozac isn't working for me. give it a few weeks and u will see improvement
I took it 35 years ago and it did help. I resumed taking it about 4 years ago and my results have not been so good. Have the anxiety you talk about. By accident I found out that there is an interaction with a drug I take for diabetic seizures. Use the "My Med List" found here to input all meds and any vitamin supplements. Knowing if there are interactions helps determine the questions I put to my doctors. Unfortunately my P Doc did not give answers. I have an appointment with a new doc.
Hey all,
I know this is an old question. I just started Prozac (10mg) 3 days ago & have increased anxiety/panic. I'm also experiencing extreme burning in the back of my throat. Not sure if it's GERD due to anxiety? Was jw if anyone else had experienced this. If so, when does this end? Also when do you take the Prozac? Morning or bedtime?
Take Prozac in the am. It's a stimulant.

The burning may be the pill. U should take it w food. Prozac always gave me indigestion. And the heightened anxiety lasted for me 3 to 4 weeks. So hang in there. It gets better
I myself started prozac 12 days ago. I started it for anxiety and panic. My panic attacks have gotten a lot worse where my heart rate has increased to over 170 a few times i have read from a lot of people to stick with it, but waking up every morning with a very high heart rate is started to become hard to deal with as well as the nausea. My doc said shes unsure if i should wait it out, however my med options are becoming limited. Did anyone else improve after week 2 to 3? I was uped to xanax .5 2x a day, but it hardly helps in the morning. Thank you.
Hi all,
I'm now on day 13 of Prozac (10mg). The throat burning has subsided. My Reflux comes & goes, I've had some diarrhea yesterday & today. My anxiety remains heightened, but I'm powering through this. I felt extremely tired/spaced out/foggy today but persevered. I'm limited to SSRIs that I can take because I'm trying to get pregnant. In the past I've taken Zoloft, Celexa, Lexapro, & Paxil. This has been by far the drug with the most anxiety provoking side effects. I'm hoping as I ease into week 2.5-3 that I start to feel better, less depressed, anxious, & side effect free. I appreciate everyone's feedback more than you know.
the anxiety will subside. it takes 4 weeks. I am moving on from Prozac. I'm 2 months in and my anxiety is still here and some panic. idk what the Dr will suggest.
I stopped the Prozac & switched allegiances lexapro 2 weeks ago. My 1st week on Lexapro I felt much calmer. I was still extremely anxious/panicky after 5 weeks of Prozac. Week 2 on Lexapro I feel a heightened anxiety/panic. Not sure if it’s the Lexapro or PMS/hormones. I plan to remain on lexapro hoping it works. However, I still have Reflux. Anyone else have a similar experience? When will the lexapro lift my spirits/reduce panic/anxiety?
I took Prozac for a few years a while back and it worked awesome for my depressions and panic. It ended up pooping out in 2013 and I was moved to Wellbutrin. About 7 weeks ago my panic and anxiety came back so my Dr added 10 mg of Prozac back to my routine. It's been 6 days. I can't tell if all this anxiety and panic is from the Prozac or just how I felt before I started. It's worse in the am and I am taking .5mg of Xanax as soon as I wake up and maybe .5 in the middle of the day to help w any more. I am increasing to 20mg tomorrow. Should I keep waiting out these effects? I'm so worried I'm wasting my time even though it did work years ago.
Hi Cheryl,
I have been on Prozac for 5 weeks from 20mg to 40. The anxiety has been terrible, and always in the morning. I also take .05 of Xanax and it helps. I hear after 6 weeks it starts to get better. I also feel like should I keep on this or should I go off. Have you heard anything back from your DR?Hope you are doing better.
Hi thanks for responding. I feel better today. I have my klonopin handy. I try to stick it out til mid day before I take one. I see the doctor tomorrow. Im.gonna stick it out.
Good, I go on Thursday, lets check in with each other. I have also been using Bahn Flower remedies ,it is all natural, and you can get it on Amazon. I have been using it at night and during the day to take the edge off and it has helped. Hope things start getting better for both of us!
Yeah this is a horrible illness of the mind. I will keep in touch and let u know.
I can see that this is an old post with a lot of recents post, all having the same issue of major anxiety with recent Prozac use.
My two cents... I have taken Prozac generic, fluoxetine, several times in my life, never longer than 1 year, usually just to help me through a rough season. I have NEVER had anxiety from it until this time. I am 30 days into a script of it and the anxiety is horrible, starting at 2 am and not letting up until after 4 pm for the last week! Reading others comments of the same, my money says it's something new, i.e. filler, in the drug. I'm done with it!
I swear this is happening to me. Been on 40mg for 3.5 years just fine. Last month my generic changed... paid no attention. Started having an anxiety flare up and my doc increased me to 60. 6 days into the higher dose I thought I was going to crawl out of my skin. I backed down to 40 and demanded my original generic brand. Still waiting for improvement...
