Even with careful management of health, there are still days when severe asthma attacks happen. At these times I turn to the liquid albuterol and the nebulizer kit for help. It usually takes more than 2 puffs to free myself from the discomfort. Minutes later, my lungs responds and opens up for more of the medicine and improve my state. If your asthma occurs after you realized you are not bringing an inhaler, or if you take more than 17 gram MDI every month, you might be mismanaging your asthma and might just be endangering your life in either way. I suggest you consult a pulmonologist, ask for appropriate treatment and take a complete pulmonary function test. The procedure usually takes an hour and can be scary to the claustrophobic, but it is the best means for the doctor to help you out. Very importantly, get on a program that will allow you to better prevent asthma from bothering you so much.
