allergic rhinitis
"My PCP prescribed Azelastine 7 days ago for my nasal congestion. It worked like a charm on day 1 and I was able to have a good night's rest finally after 2 weeks of pre-allergy season nasal congestion. But a few days later, not sure what happened. I am more congested than ever.  It keeps me awake at night and then when it does kick in several hours later that's when it's almost time for me to wake up for work.  And that bitter taste it leaves behind is horrible. I'm always trying to cough it up before it gets down my throat. I would not recommend this drug. Hasn't worked for me since day 2."
