Do you know of any good way to help asthma symptoms?

Hi! I have asthma and am on meds but, i cough all the time and tomarrow i am going to be outside in the city and need to know if there is something that can help my asthma symptoms along with my inhaler. I am also prone to sickness and am trying not to get sick.
any suggestions?
Please be kind:)

It is always best to ask you MD about these issues because asthma affects individuals differently. If you know what some of your triggers are, it is always best to avoid them. Perhaps if you know you are going to have a reaction, take a breathing treatment prior to the outing. I know that asthmatics tend to have a rescue inhaler as well as nebulizers they sometime use at home (especially in these colder months). Also your doctor should have prescribed you a long acting agent such as serevent (usually 2 puffs twice a day) as a maintenance therapy. Corticosteroids are also good antiinflammatory agents. Intal and Tilade are good first-line preventer antiinflammatory agents. Depends on your type of asthma as well. Is it intrinsic or extrinsic? As always check with your MD because they can make a specialized plan and recommendations for you.
