Thank you very much for the comment. It was of great help.
No you want to use the salmeterol/fluticasone mix. Part of asthma is the inflammation which ventolin does NOT treat at all. If you end up abusing it, you could get to the point of having so much inflammation and muscous in your lungs that you can't breathe, even with extra medication.
The study will salmeterol that showed the increase in death gave salmeterol to the patients in addition to their current medication, thus some were not taking anything other than ventolin. Salmeterol has the same affect on the lungs as ventolin, opening up the airway but the affect is longer. So by opening up the airways, by the time you are having problems you are so full of muscous there is nothing that would help and the person ends up suffocating. This is way salmeterol should always be given with a corticosteroid that helps with inflammation.
The risk of osteoprosis and everything else is a small risk for how much the puffer helps. Look up the side affects of ventolin use, if you are abusing that medication you are much more likely to have problems then if you use the maizar and ventolin properly together.
You will feel a lot better then having to take ventolin all the time. Use one inhaler properly (try not to miss any doses) and see how you feel at the end. Use a journal (or the asthma tracker on here) to keep track of symptoms and peak flows if you have a meter. Assess at the end of one inhaler (probably 2-4 weeks) and then talk to your doctor if you don't feel like you want to continue using it. But make sure any change in medication is passed through the doctor so they know what is going on and what you are/are not using.
Let us know if you have any other questions and how the inhaler is working.
