Steroid inhalers are often prescribed for people like you with severe asthma. The medication is usually taken daily with a spacer to lessen asthma symptoms such as inflammation and swelling of the airway and extra mucous production. Steroid inhalers are effective and have few side effects. The most common side effect is irritation in the mouth. Some people have extra hair on their bodies for different reasons. The hair on your chest is unlikely caused from your inhaler, however it’s a good idea to check in with your health care provider and talk about your concerns.
