Storing Olanzapine, and how long it keeps

Quoted from this product’s own FDA label. Storage belongs to the product and its device, not to the drug in general — a pen and a tablet of the same medicine are kept completely differently.

• “Store olanzapine orally disintegrating tablets, USP at 20° to 25°C (68° to 77°F) [ see USP Controlled Room Temperature].”
• “Store olanzapine tablets at 20°C to 25°C (68°F to 77°F); excursions permitted from 15°C to 30°C (59°F to 86°F) [ see USP Controlled Room Temperature].”

• “Store olanzapine tablets at controlled room temperature, 20° to 25°C (68° to 77°F) [see USP].”
• “Store Olanzapine for Injection vials (before reconstitution) at controlled room temperature, 20° to 25°C (68° to 77°F) [ see USP Controlled Room Temperature].”

How long does Olanzapine stay in your body?

The elimination half-life of olanzapine is about 21 to 54 hours (mean around 30 hours) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. The label gives the half-life as a population range: 21 to 54 hours (5th to 95th percentile, mean 30 hr) for oral olanzapine. The major circulating metabolites (10-N-glucuronide and 4'-N-desmethyl olanzapine) are explicitly described as lacking pharmacological activity, so there is no active metabolite that outlasts the parent to worry about. Half-life is longer in older adults: the mean elimination half-life was about 1.5 times greater in elderly (65+) than in younger subjects. Renal impairment: little effect (only ~7% excreted unchanged; not removed by dialysis; no dose adjustment). Hepatic impairment: a study in mild-to-moderate cirrhosis (Child-Pugh A/B) showed little effect on pharmacokinetics. Clearance is also ~30% lower in women and ~40% lower in nonsmokers, which lengthens half-life. This is the oral tablet; the long-acting olanzapine pamoate injection is a different formulation.

This is general information, not medical advice. It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.

Frequently asked questions

What does Olanzapine treat?

Olanzapine (Olanzapine) may be used to treat bipolar disorder, psychotic disorders, schizophrenia, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

How does Olanzapine work?

How much does Olanzapine cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $4.13 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.

Is there a coupon or discount for Olanzapine?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Olanzapine.
