Asthma Home > Side Effects of Metaproterenol

Some of the most common side effects of metaproterenol include nervousness, headaches, and a dry mouth. While these are mostly minor, there are some potentially serious problems to be aware of. Contact your healthcare provider immediately if you experience any of these more serious side effects, which can include an irregular heart rhythm, breathing problems that are getting worse, or signs of an allergic reaction.

An Introduction to Side Effects of Metaproterenol

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.


As with any medicine, there are possible side effects with metaproterenol sulfate (Alupent®). However, not everyone who takes metaproterenol will experience side effects. In fact, most people tolerate the medication well. When side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
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.
(This article covers many, but not all, of the possible side effects with metaproterenol. Your healthcare provider can discuss a more complete list of metaproterenol side effects with you.)
