I take 4 different inhalation s and am wondering which, if, any of the 4 should not be taken at the same time as the others, in other words, combining all 4 at the same time or how they should really be combined if they can be. Abuterol 2.5 mg, Brovana 15 meg, Budesonide 0.5 mg, Ipratropium 2.5 ml. This is the vials Quantities.
