mobic

my question is...... My son has asthma, i took him to the doctor today with acute broncial infection,which is close to walking phenomia. She gave him this samples along with a presciption for methylprednisolone which is a steroid. is it ok to take both of these together. He was prescibed with the steroid , biaxin,methocarbam,benzonatate, the things from the office that he recieved is bidex dm, singulair, nasacort, mobic, and azmacort. I need to know if it is okay for the steroid and the mobic along with the inhailer .

Thank you for your help,
