Having immediate access to a rescue inhaler is necessary for treating unexpected asthma symptoms. On the other hand, if you can't access them, they're not much use. Make sure you always have one with you everywhere you go. Having one at home, one in the car, and one in the backpack for school may be necessary for children. A strip of red tape should be placed around rescue inhalers to help people quickly and readily distinguish them from regular controller inhalers. Remember! Using steroid inhalers to treat asthma symptoms that have suddenly gotten worse is not advised!
