Nebulized hydrogen peroxide is a treatment in which hydrogen peroxide is misted into the upper respiratory tract to act as a local antibacterial agent. Nebulizer units can be rented from the clinic for a week or more depending on your specific needs. With treatment at the clinic, other nebulized ingredients are also available – such as NAC, which helps to break up mucus so it can be cleared from the nose/sinuses, and Glutathione, which is used to treat chronic respiratory problems.
