Bad Effects of Steroid Inhalers for Asthma Patients

Asthmatics use inhaled corticosteroid inhalers, sometimes daily, to reduce inflammation and swelling in the airways. While inhaled corticosteroids don’t have as many negative side effects as oral or injected corticosteroids, if high doses are long-term, a small amount is systemically absorbed and can cause side effects, some severe.

Adrenal Gland Suppression

Cortisol also maintains cardiovascular function, slows the immune response, maintains glucose levels in the body and regulates fat, carbohydrate and protein metabolism. Without it, symptoms of adrenal insufficiency occur, which include:

  • fatigue
  • muscle weakness
  • loss of appetite
  • weight loss

Fatalities can occur from adrenal crisis, the NIDDK warns.

Bone Thinning

Studies have been inconclusive on whether inhaled steroids cause bone thinning, Consumer Reports states. High doses of inhaled steroids taken long-term, however, may decrease bone density, which increases the chance of bone fractures. People older than age 50 should have regular bone density scans and take calcium and vitamin D supplements.

Oral Effects

When steroids are inhaled, a small amount may enter the mouth and throat 2. Side effects in the oral cavity include hoarseness, sore throat and dry mouth. Yeast infection known as thrush may develop from suppression of normal bacteria and overgrowth of yeast. Cough may also occur. Rinsing the mouth right after using the inhaler helps decrease symptoms, MayoClinic.com explains.

Skin Symptoms

Inhaled corticosteroids can cause skin to become thinner and to bruise more easily than normal.

The Wrap Up

High doses of inhaled steroids taken long-term, however, may decrease bone density, which increases the chance of bone fractures. Rarely, taking corticosteroids and then stopping them or lowering the dosage can cause secondary adrenal gland suppression. Inhaled corticosteroids can cause skin to become thinner and to bruise more easily than normal.
