For most people, the Maxair dosage for preventing or treating an asthma attack is two sprays. However, for some people, only one spray is needed to control the symptoms of asthma. You should not use more than 12 inhalations in one day. Some of the factors that can affect Maxair dosing include whether you use Maxair to treat or prevent asthma attacks, the severity of your asthma or other respiratory problems, and other drugs you may be taking.
The dose of Maxair® (pirbuterol acetate) that your healthcare provider recommends will vary depending on a number of factors, including:
- Whether you use Maxair to treat or prevent asthma attacks
- The severity of your asthma or other respiratory problems
- Other medications you may be taking.
As always, do not adjust your Maxair dose unless your healthcare provider specifically instructs you to do so.
Maxair inhalers will not be made, dispensed, or sold in the United States in their current form after December 31, 2013. Maxair contains chlorofluorocarbons (CFCs), chemicals that deplete the ozone layer. The U.S. Food and Drug Administration (FDA) has set this final date for the medication in order to comply with the Montreal Protocol on Substances That Deplete the Ozone Layer. The manufacturer of Maxair is working on a reformulated, CFC-free version, although it is not yet clear when that product will be available to consumers.
Maxair Dosing for Asthma
To treat or prevent an asthma attack, the recommended Maxair dosage is two sprays of Maxair as needed, as frequently as every four to six hours. For some people, only one spray will be needed to control asthma symptoms. If you need to use your Maxair asthma inhaler more often than prescribed, talk with your healthcare provider about adding an additional asthma medication. Do not use more than 12 Maxair inhalations per day.
If Maxair is not adequately controlling an asthma attack, seek medical attention immediately, as this may be an emergency.
