Asthma inhalers are considered safe because they administer vital steroids that improve lung function and minimize the likelihood that an attack will require an emergency room visit. The benefits of inhaled steroids for better asthma control far exceed their risks, according to WebMD. The side effects are few and far between, especially when the dosage is small.
Inhalers do have side effects. They can cause thrush and hoarseness, but these are unlikely results. These problems are also easy to treat through a prescription throat lozenge or by rinsing the mouth.
Adults and children can use asthma inhalers. The dosage administered is usually the lowest necessary for adequate treatment, particularly when it is prescribed for children.
