Does Flovent (fluticasone propionate) cause side effects?
Flovent (fluticasone propionate) is a glucocorticoid which is related to the naturally-occurring steroid hormone, cortisol or hydrocortisone, produced by the adrenal glands used to treat asthma in patients four years of age or older.
Glucocorticoid steroids have potent anti-inflammatory actions. When used as an inhaler, Flovent travels to the airways in the lung. In asthmatic patients, the suppression of inflammation within the airways reduces the spasm of muscle cells that surround the airways as well as the accumulation of fluid and cells that accompanies the inflammation which lead to narrowing of the airways.
The narrowing makes it difficult to get air into and out of the lungs. When used in lower doses, very little Flovent is absorbed into the body. When higher doses are used, Flovent is absorbed and may cause side effects elsewhere in the body.
Common side effects of Flovent include
- headache,
- upper respiratory infections,
- throat irritation,
- nasal congestion,
- nasal discharge,
- hoarseness or difficulty speaking,
- bronchospasms (wheezing), and
- oral candidiasis or thrush.
Serious side effects of Flovent include
- weakening bones and promoting fractures,
- suppression of the body's ability to make its own natural glucocorticoid in the adrenal gland,
- allergic reactions (such as swelling of face, throat swelling, tongue swelling, rash, hives, and breathing problems),
- suppression of growth,
- weakened immune system,
- increased risk of glaucoma (increased eye pressure), and
- cataracts.
Drug interactions of Flovent include ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nelfinavir, and telithromycin, which may increase levels of Flovent in the body by reducing the breakdown of Flovent by liver enzymes. This may increase side effects of Flovent.
Adequate studies of Flovent during pregnancy have not been done. Flovent use during pregnancy should be avoided unless the potential benefit justifies the potential but unknown risk to the fetus.
It is unknown if Flovent is secreted in breast milk. Other medications in the same class as Flovent are secreted into breast milk. It is not known whether the small amounts that may appear in the milk affect the infant. Consult your doctor before breastfeeding.
What are the important side effects of Flovent (fluticasone propionate)?
The most common side effects of fluticasone are:
- headache,
- upper respiratory infections,
- throat irritation,
- nasal congestion,
- nasal discharge, and
- hoarseness or difficulty speaking.
Fluticasone may also cause bronchospasms (wheezing). Bronchospasms should be treated with a rescue inhaler.
Oral candidiasis or thrush (a fungal infection) may occur.
High doses of inhaled fluticasone may decrease formation and increase break-down of bone thereby weakening bones and promoting fractures.
Higher doses of fluticasone also may suppress the body's ability to make its own natural glucocorticoid in the adrenal gland. People with suppression of their adrenal glands (which can be diagnosed by a testing performed by doctors) need increased amounts of glucocorticoids, probably by the oral or intravenous route, during periods of high physical stress when glucocorticoids are particularly important.
Inhaled steroids may suppress growth, weaken the immune system, and may increase the risk of glaucoma (increased eye pressure), and cataracts.
Flovent (fluticasone propionate) side effects list for healthcare professionals
The incidence of common adverse events in Table 1 is based upon 7 placebo-controlled US clinical trials in which 1,243 patients (509 female and 734 male adolescents and adults previously treated with as-needed bronchodilators and/or inhaled corticosteroids) were treated with Flovent (fluticasone propionate) Inhalation Aerosol (doses of 88 to 440 mcg twice daily for up to 12 weeks) or placebo.
Adverse Event | Placebo (N = 475) % | Flovent 88 mcg Twice Daily (N = 488) % | Flovent 220 mcg Twice Daily (N = 95) % | Flovent 440 mcg Twice Daily (N = 185) % |

Neurological | ||||
Headache | 14 | 17 | 22 | 17 |
Average duration of exposure (days) | 44 | 66 | 64 | 59 |
Table 1 includes all events (whether considered drug-related or nondrug-related by the investigator) that occurred at a rate of over 3% in groups treated with Flovent (fluticasone propionate) Inhalation Aerosol and were more common than in the placebo group. In considering these data, differences in average duration of exposure should be taken into account.
These adverse reactions were mostly mild to moderate in severity, with £2% of patients discontinuing the studies because of adverse events. Rare cases of immediate and delayed hypersensitivity reactions, including urticaria and rash and other rare events of angioedema and bronchospasm, have been reported.
Systemic glucocorticoid side effects were not reported during controlled clinical trials with Flovent (fluticasone propionate) Inhalation Aerosol. If recommended doses are exceeded, however, or if individuals are particularly sensitive, symptoms of hypercorticism, e.g., Cushing syndrome, could occur.
Other adverse events that occurred in these clinical trials using Flovent (fluticasone propionate) Inhalation Aerosol with an incidence of 1% to 3% and that occurred at a greater incidence than with placebo were:
- Ear, Nose, and Throat: Pain in nasal sinus(es), rhinitis.
- Eye: Irritation of the eye(s).
- Gastrointestinal: Nausea and vomiting, diarrhea, dyspepsia and stomach disorder.
- Miscellaneous: Fever.
- Mouth and Teeth: Dental problem.
- Musculoskeletal: Pain in joint, sprain/strain, aches and pains, pain in limb.
- Neurological: Dizziness/giddiness.
- Respiratory: Bronchitis, chest congestion.
- Skin: Dermatitis, rash/skin eruption.
- Urogenital: Dysmenorrhea.
In a 16-week study in patients with asthma requiring oral corticosteroids, the effects of Flovent (fluticasone propionate) Inhalation Aerosol, 660 mcg twice daily (N = 32) and 880 mcg twice daily (N = 32), were compared with placebo.
Adverse events (whether considered drug-related or nondrug-related by the investigator) reported by more than 3 patients in either group treated with Flovent (fluticasone propionate) Inhalation Aerosol and that were more common with Flovent (fluticasone propionate) than placebo are shown below:
- Ear, Nose, and Throat:
- Pharyngitis (9% and 25%),
- nasal congestion (19% and 22%),
- sinusitis (19% and 22%),
- nasal discharge (16% and 16%),
- dysphonia (19% and 9%),
- pain in nasal sinus(es) (13% and 0%),
- Candida-like oral lesions (16% and 9%),
- oropharyngeal candidiasis (25% and 19%).
- Respiratory:
- Other:
Observed During Clinical Practice
In addition to adverse events reported from clinical trials, the following events have been identified during postapproval use of fluticasone propionate. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made.
These events have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to fluticasone propionate or a combination of these factors.
- Ear, Nose, and Throat: Aphonia, facial and oropharyngeal edema, hoarseness, laryngitis, and throat soreness and irritation.
- Endocrine and Metabolic: Cushingoid features, growth velocity reduction in children/adolescents, hyperglycemia, osteoporosis, and weight gain.
- Eye: Cataracts.
- Non-Site Specific: Very rare anaphylactic reaction.
- Psychiatry: Agitation, aggression, depression, and restlessness.
- Respiratory: Asthma exacerbation, bronchospasm, chest tightness, cough, dyspnea, immediate bronchospasm, paradoxical bronchospasm, pneumonia, and wheeze.
- Skin: Contusions, cutaneous hypersensitivity reactions, ecchymoses, and pruritus.
- Eosinophilic Conditions: In rare cases, patients on inhaled fluticasone propionate may present with systemic eosinophilic conditions, with some patients presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, a condition that is often treated with systemic corticosteroid therapy.
- These events usually, but not always, have been associated with the reduction and/or withdrawal of oral corticosteroid therapy following the introduction of fluticasone propionate.
- Cases of serious eosinophilic conditions have also been reported with other inhaled corticosteroids in this clinical setting.
- Physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients.
- A causal relationship between fluticasone propionate and these underlying conditions has not been established.
What drugs interact with Flovent (fluticasone propionate)?
- Fluticasone propionate is a substrate of cytochrome P450 3A4. A drug interaction study with fluticasone propionate aqueous nasal spray in healthy subjects has shown that ritonavir (a highly potent cytochrome P450 3A4 inhibitor) can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations.
- During postmarketing use, there have been reports of clinically significant drug interactions in patients receiving fluticasone propionate and ritonavir, resulting in systemic corticosteroid effects including Cushing syndrome and adrenal suppression.
- Therefore, coadministration of fluticasone propionate and ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects.
- In a placebo-controlled, crossover study in 8 healthy volunteers, coadministration of a single dose of orally inhaled fluticasone propionate (1,000 mcg) with multiple doses of ketoconazole (200 mg) to steady state resulted in increased mean plasma fluticasone propionate exposure, a reduction in plasma cortisol AUC, and no effect on urinary excretion of cortisol.
- Caution should be exercised when Flovent (fluticasone propionate) Inhalation Aerosol is coadministered with ketoconazole and other known potent cytochrome P450 3A4 inhibitors.

COPD vs. Asthma (Differences and Similarities)
COPD (chronic obstructive pulmonary disease) and asthma both have common symptoms like coughing, wheezing, shortness of breath, and a tight feeling in the chest. COPD is caused by tobacco smoking, while asthma is caused by your inherited genetic makeup and their interactions with the environment. Risk factors for asthma are obesity, exposure to cigarette smoke (even secondhand smoke), and personal history of hay fever. There is no cure for either disease, but symptoms can be managed with medication. A person with asthma has a better prognosis and life expectancy than someone with COPD.

Asthma
Asthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
-
Asthma Over-the-Counter Treatment
Patients who have infrequent, mild bouts of asthma attacks may use over-the-counter (OTC) medications to treat their asthma symptoms. OTC asthma medicines are limited to epinephrine and ephedrine. These OTC drugs are best used with the guidance of a physician, as there may be side effects and the drugs may not be very effective.
