Rapid weight loss in prozac

Posted , 3 users are following.

I’ve  taking Prozac since the beginning of September. Started on 10 mg. Then got up to 20 after four weeks and now I’m taking 40 mg once a day. I have lost 30 pounds.  I have no appetite whatsoever. I’m extremely thirsty, all I can drink is water. I don’t even think about food. And for me that’s a big deal because I use to bing and gained a lot of weight from depression. Is this normal? Has anyone else lost weight???

    Hi Bree,

    Yes in the beginning you can have loss of appetite, nausea and weight loss. Once the medication gets settled in your system it should ease. Everytime you up your dose it can restart the symptoms and it can take 4-8 weeks for it to settle again. I drank smoothies when I could and constantly water. If your stomach is sensitive or upset try ginger ale or ginger tea.

    I hope this helps

    Take care
