Fluticasone
Salmeterol is a member of the drug family known as long-acting, beta-adrenergic
bronchodilators (also called beta-agonists). It is inhaled by mouth, into the lungs, to treat
asthma and prevent bronchospasm. Salmeterol is
also used to prevent exercise-induced bronchospasm.
Fluticasone is a type of corticosteroid that is
inhaled by mouth to treat and prevent
asthma, as well as other inflammatory conditions of the lungs that restrict breathing.
Oral corticosteroids 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, not
fluticasone specifically. 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 (a drug similar to fluticasone) is actually
swallowed, which may lead to reduced absorption of calcium.1 Health practitioners
may recommend calcium supplementation to individuals using beclomethasone inhalers.
DHEA
A group of women with asthma who had been
taking inhaled beclomethasone were shown to have low levels of DHEA (dehydroepiandrosterone)
compared to women with asthma who were not taking beclomethasone (a drug similar to
fluticasone).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.
Interactions with Herbs
Coleus
(Coleus forskohlii)
A test tube study demonstrated that the bronchodilating effects of salbutamol, another
beta-adrenergic bronchodilator drug, were significantly increased by the addition of
forskolin, the active component of the herb Coleus forskohlii.3 The
results of this preliminary research suggest that the combination of forskolin and
beta-agonists might provide an alternative to raising the doses of the beta-agonist drugs as
they lose effectiveness. Until more is known, coleus should not be combined with fluticasone without the supervision of a doctor.
