Hi doc! what is the medicine for asthma ?

Bronchodilators: Usually for mild intermittent astma only a bronchodilator inhaler may be enough. While persistent or moderate severe asthma will need a steroid inhaler. Avoiding smoking and enviroments that provoke asthma. Acute exacerbations may require oral steroids. Hydration is also important

Several: depends on the severity of your asthma and how controlled your symptoms are, also weather you have other problems as well that need to be dealt with to have better control on your asthma such as hay fever, your best bet is to visit an asthma specialist, an Allergist, check ACAAI.org or AAAAI.org websites to find a specialist where you live, goodluck
