From the Guidelines
Hoarseness from viral causes typically lasts between 1 to 3 weeks, and most cases resolve spontaneously within this time frame. The duration of viral hoarseness can vary, but symptoms usually last around 1 to 3 weeks 1. It is essential to note that antibiotics are ineffective against viral infections, and their misuse can lead to unnecessary costs, side effects, and contribute to antibiotic resistance 1.
Supportive Care
Instead of antibiotics, supportive care is recommended for viral hoarseness:
- Rest your voice (avoid whispering, which strains vocal cords)
- Stay hydrated with 6-8 glasses of water daily
- Use a humidifier to moisten air
- Avoid irritants like smoking or alcohol
- Try warm saltwater gargles (1/4 teaspoon salt in 8 ounces warm water) Over-the-counter throat lozenges may provide temporary relief.
When to Seek Medical Evaluation
If hoarseness persists beyond three weeks, worsens significantly, or is accompanied by difficulty breathing, severe pain, or blood in saliva, medical evaluation is necessary as these may indicate a more serious condition 1. Certain patients, such as professional voice users, may require more immediate evaluation due to the significant impact of dysphonia on their work or quality of life 1. Visualization of the larynx is the principal method to refine the differential diagnosis for a patient with dysphonia and allows for appropriately directed treatment 1.
From the Research
Duration of Hoarseness from Viral Causes
The duration of hoarseness from viral causes is not explicitly stated in the provided studies. However, some studies provide information on the treatment and management of hoarseness, which may be relevant.
- Hoarseness lasting more than three weeks should always be taken seriously and be examined laryngoscopically 2.
- There is no specific information on the duration of hoarseness from viral causes, but it is known that viral laryngitis can cause hoarseness 3.
- Corticosteroids may be beneficial in treating some infections, including viral infections, but their use should be limited to less than 3 weeks 4.
- A study on oral prednisone therapy in experimental rhinovirus infections found that steroids reduced kinin levels, but did not significantly reduce symptoms, and may even enhance viral growth 5.
Treatment and Management
The treatment and management of hoarseness from viral causes may involve:
