Zyprexa (Olanzapine) Buyer and Patient Handbook in Singapore
What is Zyprexa?
Zyprexa is an atypical antipsychotic medication used primarily to treat Schizophrenia and bipolar I disorder. It belongs to the olanzapine family, a dopamine-serotonin antagonist approved by the FDA, EMA and Singapore’s HSA. The drug is supplied as oral pill tablets in strengths ranging from 2.5 mg to 20 mg.
Who Should Use Zyprexa?
- Adults diagnosed with schizophrenia.
- Adults experiencing manic or mixed episodes of bipolar I disorder.
- Patients who have responded well to olanzapine in the past.
- Individuals without a history of severe liver impairment or uncontrolled Diabetes.
How Does It Work?
Zyprexa blocks dopamine D₂ and serotonin 5-HT₂A receptors, reducing the excess neurotransmitter activity that contributes to psychotic symptoms. Think of it as a “traffic controller” that calms over-active signals in the brain, helping thoughts and mood stay on track. Because of its receptor profile, the drug can cause metabolic changes, so regular monitoring is recommended.
Why Choose Zyprexa?
- Proven efficacy: Extensive clinical trials show rapid improvement in both positive and negative symptoms of schizophrenia.
- Convenient dosing: Once-daily tablets promote adherence.
- Brand reliability: Manufactured under strict GMP standards; generic olanzapine offers a lower-cost alternative with identical bioavailability.

Special Populations

- Pregnancy & lactation: Discuss risks and benefits with a healthcare professional; animal studies show potential fetal harm.
Lifestyle & Diet
- Avoid grapefruit juice as it can increase blood levels of olanzapine.
- Monitor weight, fasting glucose, and lipid profile regularly; olanzapine may raise blood sugar and cholesterol.

Frequently Asked Questions
How quickly can I expect to feel better?
Improvement in acute psychotic symptoms often begins within 1-2 weeks, though full stabilization may take several weeks.
Can I drink coffee while taking Zyprexa?
Yes, moderate caffeine intake is acceptable; however, excessive coffee can worsen Insomnia if you are already experiencing sedation.
Will Zyprexa make me gain weight?
Weight gain is a common side effect, primarily due to increased appetite. Regular exercise and dietary monitoring can mitigate this effect.
Is it safe to drive after the first dose?
Avoid driving or operating heavy machinery until you know how Zyprexa affects you, as initial sedation is possible.
What should I do if I feel unusually sleepy during the day?
Inform your healthcare provider; they may adjust the dose or suggest taking the tablet in the evening.
Can Zyprexa be used for depression?
Off-label use for depressive symptoms in Bipolar Disorder exists, but any such use should be discussed with a clinician.
How often should my blood sugar be checked?
Baseline testing is recommended, followed by checks every 3 months during the first year, then at least annually thereafter.
Is Zyprexa compatible with herbal supplements?
Some herbs (e.g., St. John’s wort) can induce liver enzymes and lower olanzapine levels; consult a professional before combining.

Reviews
I started the 5mg dose three weeks ago for severe insomnia and the rapid cycling paranoia. It knocks me out cold, which is exactly why I needed it, but the morning sedation is brutal. I feel like I'm dragging a lead weight around until 1 PM. My pharmacist suggested splitting the dose, but I'm worried that'll mess up the sleep effect. Also, the hunger pangs are constant. Zero appetite control now.
Been on 10mg of Olanzapine for almost two years now for Bipolar Type I maintenance. It killed the mania completely-no more impulsive spending sprees, thank God. The downside? Weight gain is real. I've gained 15 kilos. User hack: Strict intermittent fasting is the only thing that keeps the constant "munchies" under control. I avoid taking the pill until 10 PM sharp, right before bed, to minimize daytime hunger.
Switched to Zyprexa 7.5mg after another med quit working. It stabilizes the mood swings like cement stabilizes a wall, which is great for my work. However, the dry mouth is insane. Like, waking up in the middle of the night needing water constantly. My dentist isn't happy either. Pro tip: Chew Xylitol gum obsessively during the day and keep a humidifier running at night. It helps, but doesn't fix it entirely.
Terrible initial experience on the 2.5mg. I felt spaced out and fuzzy for the first eight days, like my brain was coated in cotton. The anxiety definitely decreased, but I felt too numb to enjoy anything. I almost quit. If you start, try to plan your first week when you don't need high cognitive function. I'm forcing myself to stick it out for another month, hoping the sedation eases up.
I use 5mg alongside my antidepressant, mainly to enhance the impact and control residual obsessive thoughts. This combo is powerful. The biggest problem? My cholesterol numbers shot up dramatically within six months. It really messes with your metabolic panel. If you're taking this long-term, you HAVE to get blood work done every three months. My doctor warned me, but I didn't take it seriously enough.
I tried to titrate down from 15mg myself because the fatigue on that dosage was unbearable. Big mistake. The withdrawal symptoms were harsh-nausea, dizziness, and intense irritability. You absolutely MUST titrate down slowly, maybe 2.5mg reduction every few weeks, and only with a proper plan. It's a powerful drug; don't underestimate the dependence. It works, but getting off it is a serious commitment.
This medication (20mg) saved my life during a psychotic episode. It brought me back to reality fast. The stability is amazing. Functionally, I am much better. However, my libido dropped to absolute zero. It's a huge trade-off in my marriage. It's the classic chemical castration side effect, and honestly, I don't know if I can live with it long-term, despite the clear mental health benefits.
I've been on and off Zyprexa 10mg for five years. It's the best rescue med for acute mania or panic spirals; it works quickly, usually within an hour. But it causes terrible constipation for me. User hack: Take a strong fiber supplement (like Metamucil, or just ground flaxseed) every single morning and drink a lot of water. If you don't manage the GI issues from the start, you'll regret it later.
