Answer Hi Soraya Yes, some asthma inhalers do contain steroids. These are usually referred to as “preventers” and need to be used regularly each day for them to work properly. They are often colour coded brown, purple, orange, or red. They can sometimes be mixed with other types of non-steroid asthma medication too. There are other inhalers that are not steroid based and these are often referred to as “relievers”. They are often colour-coded blue or green and these can be used whenever you feel the need rather than regularly like the steroid inhalers are. Every inhaler should come with an information leaflet that tells you what medication is in the inhaler. Also, your nurse or doctor would always go through any inhalers with you before prescribing them for you.
