@erasmus- Welcome to America and Mayo Clinic Connect. It must be scary and frustrating to be so far from medical help. We are not doctors or medical professionals We are patients helping other patients with similar difficulties. We can't give you any medical advice. I suggest that you might call your pharmacy with questions regarding dosages. Also perhaps, see if you can call and speak with your doctor.
Here is an explanation regarding nebulizers.
Nebulizer treatment works by atomizing liquid medicine into an inhalable gas form, which can then be easily breathed in by the patient as they wear a nebulizer mask. Nebulizer medicine also dissipates into the lungs faster, so it can enter the bloodstream more quickly to provide relief as fast as possible. So in short, your nebulizer is a delivery system for medicine that was prescribed for your problem. Are you experiencing more discomfort, pain or difficulty breathing? Do you think that liquid has filled your lungs out more since your last procedure?
