When you are suffering from some kind of illness or maybe astma it's not always so easy to understand what to do. The doctors may tell you to take certain medicin and for a while everything seems fine, but then the side effects kick. Before you start taking a drug or medicin it is always important to see if you can handle the side effects. Some people can even die due to them, so it's something to take very serious. On the other hand, even if you suffer a little bit from the effects of the drug, is it better than the pain from the illness. Ask a doctor and he or she will give you the right information.
