You should definitely use an inhaler daily that is prescribed to prevent an asthma attack. I use my inhaler twice a day, once in the morning and once at night before going to bed. If, however, I should be around something that triggers asthma, then I use it to control the wheezing that will occur. I have not had an asthma attack since I was a teenager and I am now 34 years old. You must be careful to not take your asthma seriously. An attack could happen at any time and having medication on hand can help you until you can get to a physician or to the emergency room. You have to remember that thousands of people lose their leives to this condition every year. So be safe and cautious when it comes to your health and life.
