Does either Ventolin or albuterol contain steroids?

No, Ventolin (albuterol) does not contain steroids.

Ventolin, which contains the active ingredient albuterol, is a sympathomimetic (beta agonist) bronchodilator that relaxes the smooth muscle in the airways which allows air to flow in and out of the lungs more easily and therefore it is easier to breath.

Ventolin is used to treat bronchospasm in people with reversible obstructive airway disease. It is also used to prevent exercise-induced bronchospasm.

There is another type of inhaler that contains inhaled steroids, also called inhaled corticosteroids. This type of inhaler is used regularly as a preventative inhaler. They work continuously to reduce swelling of the airways.
