Discuss whether a change in controller medication or decrease in the dose or strength of the inhalant would be an option. Some health experts have reported a reduction in hoarseness after backing down the dose, but this is not always effective. There is a particular inhaled steroid which is inactive until it reaches the surface of the lung (after inhalation). It seems to be an ideal inhalant for people who have adverse effects which are localized to the throat or tongue. The brand name of this unique inhaled steroid is Alvesco. It is only available by prescription. Unfortunately no currently available steroid based inhaler, (including Alvesco) eliminates the risk of dysphonia. One study referenced below suggested reduced risk with some dry powder inhalers.
Just as taking prednisone can cause side effects, reducing the dose may cause problems as well. Prednisone is not addicting like a narcotic, but many patients experience withdrawal symptoms as the dose is reduced. These often include muscle soreness, joint pain, fatigue, and depression. Know that these effects are also temporary and worth bearing to allow a cutback in your dose. If you experience any unusual symptoms as your prednisone dose is reduced, contact your doctor. It may be necessary to temporarily increase your steroid dose until you are feeling better and then taper the dose more slowly.
