When asking a patient about their medical history most patients will remember that they have had a history of asthma. How many patients can list off "Advair diskus three times daily, Sabutamol, and Singular, with occasional doses of Azithromycin as needed" not many, the response that I've heard time and time again is "The purple cirlce one" or "the orange one" or "the little square pill". I have compiled a short list of the more common medications with pictures in order to help future paramedics and students with this issue. I hope it helps!

Advair Diskus- Purple circular looking medication. Made up of Fluticasone and Salmeterol, and is used to control moderate to severe asthma when an inhaled steroid alone does not work. (see http://www.rx-pain-relief.com/allergy_asthma.html for more information)
Mometasone furoate Also known as Asmanex® Twisthaler® is a small white cylindrical tube with a larger base and numbers and a twist function at the bottom. This medication is used to block the action of both inflammatory cells and chemicals that are involved in the immune process. This medication is used for allergy induced asthma.
Flovent also known as fluticasone propionate, is an inhaler used to treat asthma. This medication is an orange puffer, and is referred to as a controller medication because it is used to reduce inflammation in the bronchi over a long period of time.
Singulair is a small square shaped pill taken for long term asthma control. Singulair can be used as an alternative to inhaled steroids, or can be used when a patient is not getting adequate control with inhaled steroids alone.

Symbicort is a pink and white tube shaped combination asthma medication containing budesonide and formoterol, given via a dry powder inhaler to help with maintenance and control of asthma
Ventolin also known as sabutamol is a bronchodilator used to treat acute exaserbations, or an “asthma attack”. Ventolin comes in a dark blue puffer. (See http://www.canadapharmacy.com/index.cfm/fuseaction/product/name/Ventolin-inhaler/product_id/1891.htm for more information)
