Anti-histamines are not really part of the initial treatment of asthma, although there are some people with clear allergy-induced asthma who do get some benefit. Steroids taken by mouth are usually only for asthma attacks. If you are feeling tight then it would also be reasonable to take a reliever B2 agonist - albuterol, albuterol inhaler as necessary for temporary relief until you get the symptoms under better control. Remember that using a spacer with a puffer metered dose inhaler is crucial to ensure effectiveness. or alternatively a Chat Doctor. In any case, its best to manage asthma under the direction of a family or respiratory physician, at least until you have formulated together a clear management plan.
