Ventolin Evohaler is a brand of the well-known blue inhaler used to relieve asthma. Ventolin inhalers contain the active ingredient salbutamol. These inhalers relieve chest tightness caused by asthma.
One or two inhalations usually relieve tightness in the chest for up to 6 hours. The onset of the action of inhaled salbutamol is almost immediate.
Inhaled salbutamol is an” as needed ” treatment. Relief inhalers are used only when there are symptoms. Most patients occasionally use the relief inhaler. When asthma is well controlled, there is usually little need for relief inhalers such as salbutamol.
The most common side effects of salbutamol tend to be dose-related and tend to occur within minutes of inhalation, usually lasting a few minutes or hours. Side effects of Ventolin are more likely to occur with higher doses or more frequent use of inhalers.
A complete list of side effects and precautions can be found in the patient information leaflet provided with Ventolin Evohalers.
