Flovent Side Effects: An Introduction

As with any medicine, side effects are possible with Flovent® HFA (fluticasone inhaler); however, not everyone who takes this medicine will have problems. In fact, most people tolerate it well. If 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 covers many, but not all, of the possible side effects with Flovent. Your healthcare provider can discuss a more complete list of Flovent side effects with you.)

Common Side Effects of Flovent

Flovent has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to those that occur in another group of people not taking the medicine.
