What should you know about inhaled glutathione?

Glutathione is a naturally occurring antioxidant involved in protecting cells from oxidative stress. Inhaled preparations are breathed into the lungs through a device such as a nebuliser. This is different from swallowing a supplement or receiving an injection, and the body handles each route differently. The intended use, formulation, device and preparation quality all affect what a person is actually receiving.

Discuss the reason for use with a licensed clinician who can review your symptoms, lung health, allergies, current medicines and pregnancy status. Ask for the exact product name, ingredients, route, device instructions, storage requirements and cleaning method. Do not put a household supplement or an unlabelled liquid into a nebuliser. Use only a preparation intended for inhalation and follow the prescriber's directions. Stop and seek advice if the treatment causes wheezing, chest tightness, persistent cough, throat irritation or dizziness.

Seek urgent help for severe breathlessness, blue or grey lips, swelling of the face or throat, fainting, chest pain or rapidly worsening wheezing after inhalation. These symptoms may represent a serious airway or allergic reaction. A cosmetic goal should not delay assessment of a breathing problem.

Ask what outcome is realistic for your reason for use, whether inhalation is suitable for your lungs, how the preparation is quality-checked, and what side effects require stopping.
