Olanzapine (Zyprexa): can it be prescribed online?
Olanzapine — sold as Zyprexa — is an effective atypical antipsychotic for schizophrenia and bipolar disorder, but it carries the strongest weight-gain reputation in its class. Here’s the full picture, including the monitoring your prescriber should be ordering.
What is olanzapine?
Olanzapine is the generic name for Zyprexa. Here are the essentials:
- An atypical (second-generation) antipsychotic
- FDA-approved for schizophrenia and bipolar disorder, including maintenance
- Among the highest metabolic and weight-gain risk in its class
- Also available as a long-acting injection (Zyprexa Relprevv)
- Sedating — often taken at bedtime
Doctors sometimes prescribe it for conditions beyond its official FDA approvals — that’s called off-label use, and it’s a normal part of psychiatric practice. Only a licensed clinician who has evaluated you can determine whether olanzapine is appropriate for your situation.
Can I get olanzapine prescribed online?
Yes, in most cases. Olanzapine isn’t a controlled substance, so a psychiatrist or psychiatric NP licensed in your state can prescribe it after a video evaluation when clinically warranted.
A responsible first prescription includes baseline weight, blood sugar, and lipids — if your prescriber skips that workup, ask about it. With olanzapine, monitoring isn’t a formality.

The first weeks
Sleepiness and a noticeable uptick in appetite are the usual early story. Weight changes can begin within the first weeks, which is why prescribers track it from day one rather than discovering it months later.
Common side effects
Weight gain, drowsiness, dry mouth, dizziness on standing, and constipation. Appetite increase — especially for carbohydrates — is frequently reported.
Don’t stop suddenly
Abrupt stops can bring rebound insomnia, nausea, and symptom return. Tapers are planned with your clinician.
The metabolic warning
Olanzapine can raise blood sugar, lipids, and triglycerides and increase diabetes risk — this is its defining safety issue. Expect scheduled labs; report excessive thirst, frequent urination, or fruity-smelling breath promptly. Like all antipsychotics, it carries the boxed warning on increased mortality in elderly patients with dementia-related psychosis. The long-acting injection form additionally requires on-site monitoring after each shot due to a rare post-injection delirium/sedation syndrome.
Frequently asked questions
Is olanzapine a controlled substance?
No. It isn’t scheduled, so telehealth prescribing after an evaluation is permitted.
Why is weight gain such a big deal with olanzapine?
It combines appetite stimulation with metabolic changes — blood sugar and lipids can shift even beyond what the scale shows. That’s why guidelines treat metabolic monitoring as mandatory with olanzapine, and why prescribers often try alternatives first when weight is already a concern.
What is Zyprexa Relprevv?
A long-acting injectable form given every few weeks, useful for people who struggle with daily pills. Because of a rare post-injection delirium/sedation syndrome, patients must be observed at the clinic for a period after each injection — it’s never a take-home shot.
I have diabetes — can I take olanzapine?
It requires careful judgment. Olanzapine can worsen glycemic control, so prescribers monitor blood sugar closely and coordinate with your diabetes care. Never adjust diabetes medications on your own when starting — loop in both clinicians.
Is olanzapine ever used for nausea?
Occasionally, off-label — for example in cancer care — because of its anti-nausea properties. That’s specialist territory though, not a reason to seek it out for ordinary nausea.
