Corticosteroids
What are CorticoSteroids?
Corticosteroids are synthetic hormones that mimic a naturally occurring hormone called cortisol.
Cortisol and corticosteroids suppress our immune systems resulting in reduced inflammation.
Corticosteroids are used to treat inflammatory diseases like asthma and psoriasis, in addition to treating vocal fold swelling.
Corticosteroids are different from anabolic steroids which are often used and abused in athletics.
CorticoSteroids prescriptions
Prednisone
Cortisone
Hydrocortisone
The most common treatment is a corticosteroid pill. Injections are another option, albeit much more rare, as the steroid will be injected directly into the vocal fold. You may be more familiar with steroid inhalers, which treat the lungs and esophagus for conditions like asthma. Inhalers are not a common treatment method for the vocal folds.
Effects of corticosteroids on the voice
Positive:
Lessens vocal fold swelling (edema)
Improves mucosal wave
Negative:
Increased risk of vocal fold hemorrhage
Increased risk of glottic thrush
Increased risk of steroid dependency
Non-vocal Side Effects
High blood pressure
High blood sugar and increased risk of diabetes
Weight gain
Psychological effects like mood swings, memory loss, and behavioral changes
Cataracts and glaucoma
Osteoporosis
Increased bruising
A slower immune system response leading to an increased risk of infection and slower healing
Recommendations
Consult a specialist, be aware of the risks, and weigh the factors.
Receive imaging (video stroboscopy) before taking corticosteroids
Use corticosteroids only for emergencies and when diagnosed
Do NOT use long-term
Steroids only treat symptoms and do not treat the underlying cause
Postpone or cancel performances, if possible
INSTEAD, TRY:
Combining intermittent voice rest with moderate voice use
Full voice rest is often not necessary or as effective as moderate voice use
Incorporate semi-occluded vocal tract exercises (bubble phonation, straw phonation, lip trills, etc.)
Alleviate other symptoms
Take guaifenesin (Mucinex) to loosen mucus without dehydrating the vocal folds
