Using them now and again is a waste of time and can lead poor asthma control.Serotide (purple inhalers) contain both bronchodilators and steroids. They also need to be used REGULARLY twice a day.Inhaler typesMetered-dose inhalers (MDI) deliver a SPRAY. You can’t just spray the medicine into your mouth as it won’t get down into your lungs.
