When should you seek professional treatment for laryngitis?

A person should seek out medical assistance for laryngitis if it has lasted for more than two weeks, claims MedlinePlus. A child should see a doctor for laryngitis if it lasts for more than one week.

Laryngitis may be prevented if people avoid others who have upper respiratory infections, explains MedlinePlus. People should also ensure that hand washing occurs throughout the day. Avoiding straining the voice and stopping smoking are also good ways to prevent laryngitis. In almost all cases, laryngitis clears up on its own, but occasionally is serious enough for immediate medical attention. If the laryngitis is causing severe respiratory distress, a person is advised to go to the emergency room.
