Inhaled steroids can deposit on your throat, causing you to develop thrush. It doesn’t matter what delivery device you use, be it a regular inhaler or a DPI (dry powdered inhaler) such as Advair® or Pulmocort Turbohaler®). All have been shown to cause this side effect. Thrush is caused by the steroid upsetting the balance of bacteria in your mouth, allowing Candida (fungus) to thrive. Thrush can present with you having a sore throat and white patches on your soft palate and tongue. You need to speak to your healthcare provider if this occurs and get medical attention. Additionally, many patients complain of painless hoarse voice after using an inhaled steroid after several months. This is also caused by the inhaled steroid affecting the muscles near the vocal cord. If this occurs, you also need to get medical attention. Spacers such as RiteFlo™ can decrease this chance from occurring
