Effectiveness
How Zyprexa Affects PatientsOlanzapine is a drug used to treat schizophrenia and bipolar disorder in adults and adolescents. It works by targeting the dopamine D2 receptor and the serotonin 5HT2A receptor, which helps to reduce hallucinations, delusions, disorganized speech and behavior, and anhedonia (loss of pleasure). Olanzapine also has been shown to help control chemotherapy-induced nausea and vomiting. In clinical trials, it was observed that 84% of individuals had a complete response on the delay phase, with over 80% control of emesis.
How Zyprexa works in the bodyOlanzapine works by blocking multiple receptors in the brain, such as dopamine, serotonin, adrenaline and histamine receptors. The blocking of dopamine receptors in the mesolimbic pathway plays a key role in preventing dopamine from having an effect at the post-synaptic receptor. Olanzapine also acts on serotonin 5HT2A receptors in the frontal cortex to reduce unpleasant side effects.

Zyprexa Reviews: What are patients saying about Zyprexa?
5Patient Review
12/28/2020 I've been on this medication for a couple of months now, and it has really helped me to manage my anxiety. It's made a world of difference for me, and I would recommend it to anyone struggling with similar issues.
5Patient Review
5/21/2022 If you're struggling with depression and anxiety, I would highly recommend this medication. In addition to my antidepressant, it's really helped me with managing my anxiety levels and getting better sleep. Just be aware that you may see some weight gain as a side effect.
4.3Patient Review
1/15/2021 Zyprexa was an absolute lifesaver for me. I had been struggling with suicidal thoughts for months, and they disappeared the very next day after taking this medication. It's not intended to be a long-term solution, but it definitely helped me in the short term. The main downside is that it made me feel incredibly drowsy and gave me a voracious appetite; however, I believe that the pros outweigh the cons in this case.
4Patient Review
5/23/2021 I've been taking this medication on and off for years, and it does a great job of curbing the paranoia and psychosis. However, it can make you feel exhausted and coming off of it is really tough - expect severe depression and suicidal thoughts. I hate that I may need to be on this medication for the rest of my life just to have any sense of normalcy.
3.7Patient Review
8/14/2022 I started on 5mg, which made me sleepy for a few months. But it stopped the crazy thoughts and I didn't gain any weight. I'm a very fussy eater and hit the gym 5 days a week so I decided to see if I could get away with microdosing. So far, 0.625 mg is still working for me.
3.7Patient Review
7/31/2021 Zyprexa is a powerful drug and I found that just a quarter of the 5mg wafer was effective in reducing negative thoughts and anxiety, as well as rumination about hateful things that have happened. Obviously, if you start to feel like a zombie, cut the dose down. It has the potential to make you hungry but you have to stay away from junk food.
2.7Patient Review
4/26/2021 Overall, this made me feel worse. I gained a ton of weight and my lab work had a lot of problems. I wouldn't recommend it to anyone with mental health issues because it will make them worse.
1.7Patient Review
6/3/2021 This pill was ineffective at treating my psychosis caused by Ptednisone
1Patient Review
1/28/2021 Unfortunately, this medication caused me to gain weight that I could not get rid of. Additionally, I got stretch marks and felt bloated all the time. If you stop taking it, you might also experience insomnia.
1Patient Review
11/28/2021 Just a warning: if you don't want to be medicated with this drug, it's important to not lose your temper. Be careful of the signs in yourself and your children, and find ways to cope before it becomes a problem.
1Patient Review
4/18/2021 Do not take this medication. It made my hallucinations worse and caused me to black out for days.
1Patient Review
4/28/2022 I was originally taking 5mg of this medication, but my doctor suggested I lower the dose to 2.5mg. For a little while, it worked well. But then, within a month, things took a turn for the worse. I was sleep-deprived and in a terrible mood all the time. The only upside was that I lost some weight; but overall, this medicine has been more of a curse than a blessing.
1Patient Review
7/6/2022 My neurologist told me to stop taking this medication Zyprexa because it showed signs of giving me Parkinson's. I had to be treated for two years before they realized I never actually had the disease; it was just a side effect of the drug. So, in conclusion, don't take this med if you can help it.
1Patient Review
4/5/2022 I would advise against taking this medication. It caused me to gain a lot of weight, and it's taken over a decade to lose most of it. There are lots of side effects that make you feel constantly hungry and emotionless.
1Patient Review
6/5/2022 The side effect I experienced was my legs twitching.
