Q. What are the side effects for the regular asthma inhalers? I am taking an inhaler (non-steroid one) for my asthma and I wanted to know what can be possible side effects to this treatment.
A. Simple inhalers that contain a material that helps with keeping the bronchi not constricted, have side effects that are related to the sympathetic nervous system- such as slight tremor, small increase in heart rate or blood pressure, but these are all in greater risk when taking in a not-inhaled way. Patients must be cautioned against using these medicines too frequently, as with such use their efficacy may decline, producing desensitization resulting in an exacerbation of symptoms which may lead to refractory asthma, meaning that the attack might not be relieved by these medications anymore.
Q. Are long flights dangerous? I'm flying next week to my vacation, and the flight is going to be rather long (almost 16 hours non-stop). Several years ago, my 75 years-old aunt had blood clot in her lung after a flight of similar length. I also heard that during flight the blood in the legs clots and that it can cause after that problems with the lungs and breathing. Does this mean it's dangerous for me to fly? Should I change my ticket to shorter connection flights? A. Do other relatives of yours have blood clotting problems too, like your aunt? You should tell a doctor about the problem your aunt had and ask if it's genetic.
