What olanzapine is used for

Olanzapine is an atypical antipsychotic: a medicine that quiets psychosis, where thoughts and perceptions stop matching reality. Its two main jobs are schizophrenia, a long-term illness that changes how someone thinks, feels and behaves, and bipolar I disorder, which brings episodes of deep depression and of mania. Chemotherapy nausea and vomiting are a less common use. Most people stay on it long term rather than for a short stretch.

How it works, and how long it takes

Dopamine and serotonin are chemical messengers that carry signals between nerve cells, and olanzapine damps their activity down. It acts at several receptor types rather than one, which is why it can settle hallucinations and fixed false beliefs as well as the sleepless, racing energy of a manic episode. Nothing happens overnight. The dose is started low and stepped up, and the full benefit usually builds over several weeks.

Taking it day to day

Olanzapine is one tablet a day, and mealtimes do not matter; what counts is choosing an hour you can repeat. Swallow it with water. A forgotten dose is never made up by taking two tablets together.

Alcohol is the main thing to watch, because it magnifies the drowsiness and light-headedness the tablets already cause. Sleeping tablets, strong painkillers and sedating antihistamines such as diphenhydramine do the same.

Side effects

Drowsiness is common in the first days and after a dose increase, and it usually fades. Dry mouth, constipation and dizziness are frequent too. Appetite often grows and weight creeps up over months; blood sugar and blood fats can rise as well. A few effects are serious. Stiff muscles, a high fever and a fast or irregular heartbeat appearing together need urgent treatment. Uncontrolled twitching of the tongue, lips or face is a slower problem that can come with long use. In older people with dementia, antipsychotics such as olanzapine carry a higher risk of stroke and death.

Olanzapine or Zyprexa

Olanzapine is listed under the ingredient name and Zyprexa under the brand name. Both are standard once-daily tablets in 2.5mg, 5mg, 7.5mg, 10mg, 15mg and 20mg, so the choice is the pack name and the pack size. A wafer that dissolves on the tongue is made as well, but neither listing is that form. Both sit in the shop's mental health category.

Is Olanzapine available to order in Hong Kong?

Olanzapine can be ordered online for delivery to Hong Kong. The range includes Olanzapine tablets in 2.5mg, 5mg, 7.5mg, 10mg, 15mg and 20mg, and generic Zyprexa tablets in the same strengths. A parcel that does not arrive within the delivery window, or arrives damaged, is sent again free, and if that is not possible the order is refunded.

What is the price of Olanzapine?

Prices vary between the two olanzapine products and between pack sizes. Every product page lists its current prices in HKD or in the currency you choose.

Do I need a prescription to order Olanzapine?

PockDose does not ask you to upload a prescription when you order olanzapine. See the ordering FAQ for details.

What is another name for olanzapine?

Zyprexa is a brand name of olanzapine, which is also sold as Olan and Oleanz. Here, olanzapine can be bought online as generic Zyprexa and olanzapine tablets. These are generics, not the original brand.

How long does olanzapine take to work?

The full effect builds slowly. Olanzapine is usually started at a low dose that is raised in steps, and it can take several weeks before the benefit on delusions, hallucinations or mania is clear. A steady daily routine is what lets that build.

Can I drink alcohol while taking olanzapine?

Better not to. Olanzapine and alcohol both slow you down, and together they hit harder than either alone. Expect more drowsiness, poorer coordination and a spinning feeling after fewer drinks than usual; the first weeks and any dose increase are when this shows most.

What is the difference between Olanzapine and Zyprexa?

They are the same medicine: olanzapine tablets in the same strengths, taken once a day. Zyprexa is the brand name and Olanzapine is the plain ingredient name, so the difference comes down to which pack name and pack size you choose.

Does olanzapine cause weight gain?

Quite often. Appetite tends to grow and weight can creep up over months, and blood sugar and blood fats may rise alongside it. These changes are slow, so they show up most clearly over long-term treatment.

Does olanzapine make you sleepy?

Sleepiness is a common early effect and often eases as the body adjusts. Until you know how the tablets affect you, driving and operating machinery are best avoided.
