How long does Fluoxetine Hydrochloride stay in your body?

The elimination half-life of fluoxetine hydrochloride is about 1 to 3 days (roughly 24-72 hours) after a single dose, lengthening to about 4 to 6 days with ongoing daily use — 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. Fluoxetine's active metabolite norfluoxetine has a much longer elimination half-life of about 4 to 16 days, so the drug clears from the body very slowly (over weeks); half-lives are also longer in people with liver cirrhosis (fluoxetine roughly 7-8 days vs 2-3 days normally).

Frequently asked questions

What does Prozac Weekly treat?

Prozac Weekly (Fluoxetine Hydrochloride) may be used to treat bulimia, major depressive disorder, obsessive-compulsive disorder, panic disorder, 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 Prozac Weekly work?

Prozac Weekly is a serotonin reuptake inhibitor. Selective serotonin reuptake inhibitors (SSRIs) block the transporter that pulls serotonin back into nerve cells, so more of this mood-related chemical stays in the gaps between neurons to keep signaling. They act mainly on serotonin, which tends to mean fewer side effects than older antidepressants.

How much does Prozac Weekly 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 $0.05 per ml, 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 Prozac Weekly?
