@drzackmd: Nebulizing hydrogen peroxide to treat a common cough is dangerous medical advice that can cause severe respiratory and systemic toxicity. Inhaling aerosolized oxidizing agents destroys the delicate epithelial lining of the trachea and bronchi, triggering acute chemical pneumonitis, direct mucosal caustic burns, and permanent disruption of mucociliary clearance mechanisms. Beyond severe airway inflammation and bronchospasm, systemic absorption of peroxides into the pulmonary capillary bed induces methemoglobinemia, oxidizing ferrous iron to ferric iron and preventing hemoglobin from releasing oxygen to vital tissues. Household disinfectants belong on external surfaces, never inside human airways. Never aerosolize toxic oxidizers into your respiratory tract. #DrZackMD #Pulmonology #PatientSafety #MedicalDebunk #EvidenceBasedMedicine
