FAQs
Common questions about loxapine
Below you’ll find answers to a few commonly asked questions about loxapine.
What brand names are available for loxapine?
Loxapine is a generic medication. A brand-name version of loxapine oral capsule isn’t available. There is a brand-name version of loxapine that’s inhaled. It’s called Adasuve. But it’s not available as a generic medication.
A generic medication is an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared with brand-name drugs.
If you have questions about brand-name versus generic loxapine, talk with your doctor or pharmacist.
Is loxapine similar to clozapine?
Yes, loxapine is similar to clozapine. Both drugs are antipsychotics approved to treat schizophrenia. However, clozapine is usually prescribed to people with schizophrenia that didn’t respond to other drugs.
Loxapine and clozapine both have a boxed warning* about the increased risk of death in older adults (people ages 65 years and above) with dementia-related psychosis. Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA).
But unlike loxapine, clozapine has other boxed warnings as well. For example, clozapine has a boxed warning about the risk of seizures. Loxapine can also cause this side effect, but the risk appears to be greater with clozapine.
If you have questions about drugs used to treat schizophrenia, talk with your doctor or pharmacist.
* For details about this side effect, see the “Interactions and warnings for loxapine” section.
How does loxapine work? And how long does it take to start working?
Loxapine’s exact mechanism of action (how it works) isn’t known for sure. The drug is thought to calm certain parts of the brain that cause schizophrenia symptoms. It can start working in as little as 30 minutes after you take a dose.
If you’d like to know more about this, talk with your doctor or pharmacist.
Uses
Uses of loxapine
The Food and Drug Administration (FDA) approves prescription drugs such as loxapine for certain conditions. The approved use for loxapine is described below.
Use for schizophrenia
Doctors may prescribe loxapine oral capsule for treating schizophrenia. It’s used for this purpose in older adults (people ages 65 years and above). It’s usually prescribed as a long-term treatment because schizophrenia is a serious condition that requires lifelong treatment.
Schizophrenia is a rare, long-term mental health condition. Early symptoms include sleep problems, irritability, agitation, anxiety, and being suspicious. More severe, later symptoms include:
- hallucinations, which involve seeing and hearing things that are not real
- delusions, which involve believing in things that are not true
- paranoia, which involves believing you’re being persecuted or spied on
Schizophrenia may cause other symptoms, too. And it can increase the risk of self-harm, alcohol or drug misuse, and death from suicide. Treatment can help reduce these risks and manage symptoms.

Warnings for loxapine
Loxapine should be taken cautiously by certain people.
Boxed warning: Increased risk of death in certain older adults
Loxapine has a boxed warning about the increased risk of death in older adults (people ages 65 years and older) with dementia-related psychosis. Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA).
Loxapine is not approved to treat dementia-related psychosis in older adults. It should not be used for this purpose.
Studies of antipsychotic drugs, including loxapine, have shown an increased risk of death in certain older adults. This involved those receiving treatment for dementia-related psychosis with antipsychotic drugs. Causes of death varied, but deaths due to heart problems and infections were most common.
If you have concerns about the increased risk of death in older adults with dementia-related psychosis, tell your doctor. They’ll likely recommend a drug other than loxapine for older adults.
