Fluoxetine apetite and weight changes..

Hi... it's my first day on these my doctor gave me them today as my anxiety is very bad and causeing me to hurt myself to stop me from thinking the things I am (it's a way of me copeing but I way I need to stop) I hope they work for me.. and I dnt get worse...

I realize this thread started over 2 years ago but thought I'd chime in here with my own experience. I have been dieting for years - in fact for most of my life and never could lose much weight.

I was put on Fluoxetine 1 month ago for anxiety, and take 10 mgs each day. And I have suddenly lost 12 lbs this first month, without even trying! Not only is my anxiety way down, but I am losing weight and couldn't be happier. I still have 20 lbs to go but figure it'll eventually come off, little by little.

I should have taken this medicine years ago when my anxiety (panic attacks) started. Oh well, better late than never!

I know this is an old thread but I've just started taking this and felt I'd suddenly lost weight and I've lost 5 pounds in 4 days!!!

I've struggled with weight loss due to having crohns so I'm not complaining 

I have however had really bad broken sleep and hot flushes so far as other side effects.

Do these side effects ever go away? 

Hey Alex

I am back on them after a year off.

Appetite comes and goes really after about 3 weeks but in general I find that I just don't fancy anything, when normally I would eat a million biscuits, on flu I just don't want to. Last year i lost about 10lb in 6 weeks or so. I tapered and when i stopped taking it i did gain a few pounds back but thats because i am just greedy. Im not allowing that again. I think there is an elemant of metabolism boosting with fluoxetine. That nervous energy burns loads of calories. That's the part I like. I don't enjoy the lack of sex drive ( not that I have one anyway!) I also have no emotions or feelings when on it. Very strange . Also constipation, but that could e due to lack of nutrition, and I don't sleep too well, but to be fair I don't sleep that great anyway.

So to answer your question, I would predict a good few pound weight loss during the first 2 to 3 months, then it slows down as your body adjusts. Everyone is different though. Good luck ! I hope you have a successful journey and you find happiness 😍

Hi guys I’ve come off fluoxetine for many years straight swap next day to citalapram I was on them for 5 weeks then got changed next day to venlafaxine... I’ve got absolutely no appetite I’ve lost around 10kgs in 8 weeks and when I lay down at night I’m getting pins and needles in my hands...

My insomnia is so bad im having to take quatiapine has any one else suffered from this it’s been even a pretty scary ride 

How much Prozac did you take ? This may be a late reply sorry it’s been 3 years lol

I found that taking 20mg everyday for the last 12 days have started to make me binge again.  The first few days I felt normal now it’s like a high on a binge and the high lasts for a hour when I wake up 

Oh my, wish I had found this thread when I first started taking Flu (thought you were all getting ill before I realsed that you meant Fluoxetine- lol). 

I'm on my 2nd month now- the first was pure hell, but I'm so glad I stuck with it as I feel so much more normal and can start to live.

My side effects were very much like getting the flu or a virus. I was so fatigued and my chest hurt. It was as if my depression had manifested itself into a physical form that I just couldn't get away from, or hide. I'd been hiding it for years. I was unable to get out of bed for a couple of weeks and everything was so much worse than the doctor had explained. She said I would feel worse and I presumed it was mentally rather than physical. I was tired, had headaches, dizziness, would pass out from exhaustion if I did anything for more than an hour or two, increased anxiety and fear. 

I had started taking Flu in the mornings but ended up switching the times to the evenings as I slept as soon as I took them. 

I'd recommend anyone taking them to test the time of day that best works for them. If they give you more energy and keep you awake, take them in the am, if they make you fall asleep, take them in the pm. 

Emotionally I feel stronger, I cant recall when the last time I felt this good. 

I did stumble on this thread though as now that I have motivation, I've started dieting and exercise. I was getting concerned that eating 1200 calories now seems like a chore. Most people complain that 1200 isn't enough and I'm having the opposite problem....

If it's a side effect of the drug I feel better, I shall trust MFP again . 

Thank you for starting this thread.
