Ventolin is a brand name for the inhaled asthma medicine salbutamol. Ventolin side effects are the same or similar to those of other salbutamol inhalers.
Ventolin Evohaler is a salbutamol asthma inhaler which delivers a puff of salbutamol when the end of the inhaler capsule is pressed down.
Other asthma inhalers are breath actuated and release a puff of salbutamol only when air drawn in through the inhaler nozzle, e.g. Salamol Easi-Breathe asthma inhaler.
All the following asthma inhalers contain salbutamol; Ventolin Evohaler®, Ventolin Accuhaler® (dry powder for inhalation), Salamol Easi-Breathe®, Airomir Autohaler®, Airomir Aerosol inhalation®, Asmasal Clickhaler® (dry powder for inhalation), Salbulin Novolizer® (dry powder for inhalation), salbutamol (non-proprietary) aerosol inhalation- includes Salamol® and Salbumalin®, salbutamol (non-proprietary) dry powder for inhalation – includes Easyhaler® Salbutamol, and Pulvinal® Salbutamol.
Ventolin side effects
Like all medicines, Ventolin can cause side effects, although most people taking asthma inhalers at the recommended dose do not experience side effects.
Most Ventolin side effects start within minutes of inhaler use and last for between a few minutes and a few hours. They are caused by the active ingredient, salbutamol, although very little inhaled salbutamol finds its way from the lungs into the circulation.
The dose of salbutamol delivered by inhalers is low, usually 100 mcg per puff. The amount absorbed into the blood stream is usually too low to cause side effect. However, some people are sensitive to even small amounts of salbutamol. Occasionally Ventolin and other asthma inhalers are given at high dose (frequent puffs) and this can cause a build up of salbutamol in the circulation.
The side effects of Ventolin are usually dose related, the higher the dose (number of puffs used), the more side effects are likely to occur.
Salbutamol has similar properties to adrenaline, although salbutamol does not exert the same effects as adrenaline throughout the body. Salbutamol’s adrenaline like action is selective and its effects are restricted mainly to the lungs. Inhaled salbutamol works in the lungs by opening up airways and making it easier to breath.
Side effects are usually short lived because salbutamol is broken down in the circulation over a period of a few hours. A few hours after an inhaler is used very little salbutamol remains in the circulation.
Occasionally asthma inhalers cause side effects related to throat irritation produced by constituents of inhalers, either the active ingredients or the propellent.
