What is loxapine inhalation?

Loxapine is an antipsychotic medication. It affects the actions of chemicals in your brain.

Loxapine is used to treat agitation related to schizophrenia or bipolar disorder.

Loxapine inhalation is given only in a hospital or clinic setting where any breathing problems can be quickly treated.

Loxapine inhalation may also be used for purposes not listed in this medication guide.

Important Information

You should not use this medicine if you have breathing problems that can cause bronchospasm (such as asthma or COPD), or if you are currently having trouble breathing with cough and wheezing. You should not use loxapine if you have ever had breathing problems after using it in the past.

Loxapine inhalation can cause bronchospasm (wheezing, chest tightness, shortness of breath) that can lead to serious lung problems or make your breathing stop. This medicine must be given in a hospital or clinic setting where your doctor can quickly treat any serious side effects that occur.

Loxapine is not approved for use in psychotic conditions related to dementia. Loxapine may increase the risk of death in older adults with dementia-related conditions.

How is loxapine inhalation given?

A healthcare provider will give you this medicine in a hospital or clinic setting where you can be quickly treated if any serious side effects occur.

Loxapine inhalation is usually given once every 24 hours as needed.

This medicine comes in a single-use inhaler device. You will be shown how to use this device. Follow all directions carefully.

The inhaler device has a green indicator light on one side and a pull tab at one end. When the pull tab is released the green light will turn on, showing that the device is ready for use.

Once the green light turns on, you must use the inhaler within 15 minutes or the device will deactivate. Do not try to use the inhaler if the green light is off.

While using the loxapine inhaler device, you may hear a clicking sound and the device may feel warm. These are normal functions. After you have inhaled your dose, the green light will turn off to show that the entire dose has been used.

You will be watched closely for at least 1 hour after using loxapine, to make sure you do not have any breathing problems.

Each single-use inhaler device of this medicine is for one use only. Throw the device away after one use.

What happens if I miss a dose?

Since loxapine inhalation is used when needed, you may need only one dose. Loxapine inhalation is usually not given more than once in a 24-hour period.

What happens if I overdose?

Since this medicine is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
