Inhalation may cause a raspy throat?


Dear Doctor, my husband was hospitalized for nearly a week at the end of March this year due to an asthma attack.
Upon his discharge, the doctor prescribed a bronchodilator for him to manage his asthma.
However, he has been experiencing a persistent scratchy sensation in his throat, and during an examination, small white spots were found on the inner part of his throat.
He has been rinsing his mouth after using the inhaler.
Is this normal?

Hello: Regarding your mention of a scratchy throat, it indicates that even though you have been rinsing, it may not have been done thoroughly.
In more severe cases, it can lead to a hoarse throat or even the development of white oral thrush.
Therefore, it is recommended to rinse your mouth at least five times after inhalation and then spit it out.
Thank you for your inquiry.

More Info


It is not uncommon for individuals using inhalers, particularly corticosteroid inhalers, to experience a scratchy or irritated throat. This sensation can be attributed to several factors related to the inhalation process and the medication itself.

Firstly, inhalers deliver medication directly to the lungs, but some of the medication can deposit in the throat and mouth. This can lead to local irritation, which may manifest as a scratchy or dry throat. The presence of small white particles in the throat could be indicative of medication residue, especially if the inhaler used is a corticosteroid. These medications are designed to reduce inflammation in the airways, but they can also cause irritation in the oral cavity and throat if not properly rinsed away after use.

Rinsing the mouth and throat after using an inhaler is a recommended practice to minimize this irritation and to prevent the development of oral thrush, a fungal infection that can occur due to the immunosuppressive effects of corticosteroids. If your husband is rinsing his mouth after each use and still experiencing discomfort, it may be worth considering a few additional strategies:
1. Technique: Ensure that he is using the inhaler correctly. Improper technique can lead to more medication being deposited in the throat rather than the lungs. A spacer device can be helpful in this regard, as it allows for better delivery of the medication to the lungs and reduces the amount that settles in the throat.

2. Hydration: Encourage him to stay well-hydrated. Drinking water can help soothe the throat and keep the mucous membranes moist, which may alleviate the scratchy sensation.

3. Humidification: Using a humidifier in the home can add moisture to the air, which may help reduce throat irritation, especially in dry environments.

4. Consultation with a Healthcare Provider: If the scratchy throat persists or worsens, or if he develops additional symptoms such as pain, difficulty swallowing, or persistent cough, it would be advisable to consult with a healthcare provider. They may want to examine his throat further to rule out any other underlying issues, such as an allergic reaction or infection.

In summary, while a scratchy throat after using inhalers can be a common side effect, it is important to monitor the situation closely. Proper inhaler technique, good oral hygiene practices, and adequate hydration can help mitigate these symptoms. If concerns persist, seeking medical advice is always a prudent step to ensure that there are no other complications at play.
