Asthma Home > Metaproterenol Dosing

For most people, the recommended metaproterenol dosage is two or three sprays as needed every three to four hours. However, you should not take more than 12 inhalations per day. You should always have a metaproterenol asthma inhaler on hand, as failing to treat an asthma attack can quickly turn into a medical emergency. Among the factors that can affect metaproterenol dosing are the severity of your respiratory problem and other medications you may be taking.

An Introduction to Metaproterenol Dosing

Metaproterenol is no longer available in the United States. The manufacturer of this medication decided to stop making it in order to comply with regulations concerning chlorofluorocarbons (CFCs), chemicals that may deplete the ozone layer. The product was rarely used anymore; had it been more popular, the manufacturer probably would have chosen to reformulate it without CFCs, instead of just discontinuing it.

 

The dose of metaproterenol sulfate (Alupent®) your healthcare provider recommends will vary depending on a number of factors, including:
 
  • The severity of your asthma or other respiratory problems
  • Other medications you may be taking.
     
As always, do not adjust your metaproterenol dose unless your healthcare provider specifically instructs you to do so.
 
This article focuses on the metaproterenol inhaler. Metaproterenol also comes in tablets, syrup, and a solution that is inhaled using a machine called a nebulizer.
