Corticosteroids are inhaled by mouth to treat and prevent asthma, as well as other inflammatory conditions of the lungs that restrict breathing. They are inhaled into the nose to treat and prevent symptoms of hay fever and other allergies. In addition, some agents may be used to prevent recurrence of nasal polyps following surgical removal.

The information in this article pertains to inhaled corticosteroids in general. The interactions reported here may not apply to all the Also Indexed As terms. Talk to your doctor or pharmacist if you are taking any of these drugs.

Interactions with Dietary Supplements

Calcium
Most of an inhaled dose of beclomethasone is actually swallowed, which may lead to reduced absorption of calcium.1 Health practitioners may recommend calcium supplementation to individuals using beclomethasone inhalers.

Dehydroepiandrosterone (DHEA)
A group of women with asthma who had been taking inhaled beclomethasone were shown to have low levels of DHEA compared to women with asthma who were not taking beclomethasone.2 The authors speculated that this effect may partially explain how corticosteroids can cause osteoporosis. However, more research is needed to confirm these suspicions and to evaluate whether supplemental DHEA is beneficial to patients taking inhaled corticosteroids.
