Flonase (fluticasone) is a synthetic steroid of the glucocorticoid family of drugs and is prescribed for the control of symptoms of allergic and non-allergic rhinitis. Flonase is available as a generic drug, and dosing is usually administered as two sprays in each nostril once daily, or one spray in each nostril twice daily.
The most common side effects of Flonase (fluticasone) include:
- back pain,
- sore throat,
- menstrual problems,
- loss of interest in sex,
- sinus pain, and
- sores or white patches inside mouth or around your nose.
Flonase has also been associated with hypersensitivity reactions (for example, skin rash, itching, facial swelling, and anaphylaxis).
The recommended starting dosage of Flonase in adults is 2 sprays (50 mcg of fluticasone propionate each) in each nostril once daily (total daily dose, 200 mcg). Drug interactions and warnings include Norvir (ritonavir) and Nizoral (ketoconazole). Taking either one of these drugs with Flonase may increase the blood concentrations of Flonase and potentially increase its side effects. Flonase should only be used during pregnancy when it is absolutely necessary. There have not been adequate studies of Flonase and concentrations in breast milk; therefore, Flonase should be avoided while breastfeeding unless it is absolutely necessary.
