Probably. If the post nasal drip is caused by allergy, this is a very effective combination. However, it is most likely caused by some degree of chronic sinusitis; if mild, the meds will work, but if you have severe chronic sinusitis, they may not. This combination is a very reasonable place to start, but be sure to followup with your doctor if it's not helping within 2-4 weeks.
One or the other. Depending on the cause of post nasal drip, either azelastine or fluticasone can be beneficial for allergic or non-allergic rhinitis, vasomotor rhinitis. All can cause post nasal drip, as can a cold. Saline nasal spray or rinses are also beneficial to improve post nasal drip.
See Below. Post nasal drip is most often caused by allergies, although there is a syndrome called non-allergic rhinitis that can sometimes cause it. Flonase treats allergic inflammation which will reduce stuffiness and drainage. Azelastine will treat drainage, sneezing, itching, and it treats the non-allergic rhinitis if it's there as well.
The dr. Prescribed azelastine and fluticasone nasal sprays. 1. Can I use both at the same time? 2. If not, how long do I wait between each?
Yes! I generally use the Astelin (azelastine) first, as it is a decongestant. Inhale gently, it tastes yucky, but works well! Then do the fluticasone at night or a couple minutes after the astelin (azelastine).
Yes. Should be effective.
Nasal sprays. Azelastine- a nasal antihistamine spray. This is like claritin/fexofenadine and should not make one sleepy fluticasone- a nasal steroid spray. This is usually intended to decrease the symptoms of nasal allergies. While the main indications for both relate to nasal congestion related to allergies, sometimes docs give them for things like ear dysfunction.
