Certain Antibiotics and Antifungals
Some antibiotics and antifungals can increase the level of
Flonase in your blood, perhaps increasing your risk of
Flonase side effects. In particular, too much Flonase in your blood can suppress your body's ability to produce natural steroids, which can cause serious consequences. This interaction is most likely to be a problem for people who take both antibiotics and antifungals on a long-term basis. Your healthcare provider may need to decrease your
Flonase dosage.
Protease Inhibitors
Protease inhibitors can greatly increase the level of Flonase in your blood, potentially causing serious side effects. In general, taking these medications together is not recommended, except in extreme circumstances. Talk to your healthcare provider before taking Flonase with a protease inhibitor.
