Your question: Could a fever lead up to my sons asthma attack coming on?
My humble answer: Asthma itself does not cause a fever. A virus may cause a low grade fever. A virus may trigger asthma symptoms. As long as you use your bronchodilator inhaler as instructed by your doctor, it is very safe. If you sense that your child is having early signs of asthma, it is a good idea to have him use his bronchodilator inhaler. At eight, he should be old enough to tell you if he feels better after using it. However, if you continue to have concerns, it's always a good idea to contact your doctor.
